Really well explained process and I like your "random information" like "almost every motor out there is 24volts". AND... you keep the fluff words to a minimum. THANKS, DAN! WELL DONE!
Thanks! Was wondering how this motor was constructed. Now I know.
Yet again.... Thank you so much for these videos. You've saved me so much money in regards to buying suitable parts for my Jive M.
So again. Much appreciated!!!
I would like to hear your ideas on removing a gearbox and plugging motors to hubs? TIA
Wrap some medium motor grade wet and dry sandpaper around the armature where the brushes run ! (use dry ) so you can bed brushes into the right shape Never put them in without bedding them to the armature as you will get arcing due to the high amperage if there not seated correctly
Great job ,you show you are a master mechanic and you speak clearly and distinctively-thank you!
Your videos are great, thanks for your time!
I have learned so much from you. I am looking forward to repairing my chair, when the motors need replacing, or repairing..
very educational
I"m working as a mecanic for the society in my city (Holland) wheelchairs bikes and scootmobils, your video's are very inspiratied for me..
Thanks mate for concise briefing
thank you for showing every thing i learned a few things thanks again .
Been looking all over for one of those hex pieces between the brake and the motor.
Thank you. Im Learning. Great knowledge imparted here
great job
Excellent video...nicely explained
BRO, THANK YOU!
Thanks for bringing this home!! I think my jerking motors are dirty brakes after seeing your video. Maybe wear, cause I do have over 1800 miles on mine and never replaced batteries in 5.5 years!!
I was able to work on my Jazzy HD motors and gearboxes and now I will clean them up from carbon from the brushes. and the Gear Boxes need grease replaced and gear boxes flushed out.
Then I should have a good backup pair.
Thanks for the help.
Also thought on bolts with
super locktite on them.
Try getting a 450 watt solder iron and heat the bolt head up really good and the lock tight stuff should not hold so tight.
It should not take to long to do it on the short bolts. Long bolts that is a different thing. you could heating the other ends of the long bolts. Hope this helps.
Thanks this was fun to watch !
Aluminium and and metal screws seems to weld together bit of copper slip prevents this that's probably why the snapped off
Dan that's a great video, I was saying WOW at most every step. Have never seen the inside of a motor or had it explained before either so this was really eye opening for me. I love seeing stuff like this! Man you really had this set up too..what with a brand new table and all that, very fancy! Used to love watching my step dad doing stuff like this on his cars and such, every once in awhile he'd let me get in there and help him, but I had no idea what I was doing, I'd just follow his instructions, but it was so fascinating to me. Always was a tomboy, lol. Home Ec classes bored me, I instead signed up for wood shop, lol. And super glad to know what's making that infernal clicking noise on my chair, hate that, can't even sneak up on anyone :(
I interspersed my 'wows' with several 'ahs'. Probably the best and most useful video I've seen for some time on TH-cam.
I used to own an Invacare Storm 4 X-plore with Tru-Track motors that was brushless and didn't make a clicking with the application of the holding brake.
Got the 7F00 bad wire error code for M1 on my daughter's Permobil M3 along with a 1505 M1 motor brake error, so now I'm armed with just enough knowledge to shred the brake and wiring for her chair! Ha! I just hope that it's the microswitch needing cleaning or something like that for the brake or a frayed wire or something I can fix or easily source locally. Anyway, so helpful your superlative videos are! Thank you so very much!
double check the connections on the main controller under the back cover on chair.. sometimes they wiggle loose - the hardshell connectors dont always get plugged in all the way :^)
also sometimes some crud can get into the brake mechanism.. i like to grab the brake/neutral levers and flip them 15-20 times like you're ANGRY at them! it can help knock dirt and stuff loose in there
just be careful with the plastics.. on the M-series chairs they like to try and escape sometimes!
I really appreciate the time you took for dismantling the motor it gave me a new look inside. I was always thinker my my old power chair jazzy 600.cause the labor they charge to fixed it is outrageous thank you again
Great video!!! You saved me a lot of time, since I am rebuilding, trying to modify, my Quickie Groove with strong&fast brushless motors (prefarebly of the same (German AMT) brand as you showed?). Lead-acid batteries will have to become lithium-ion in my beter Groove. Permobile should give you a modern/experimental future model to test, take apart and make videos of, like every creative wheelchair user should do to understand how new 'leggs' work and function. It remains hard to explain why innovations are kept out of wheelchair manufactoring (like omni wheels on indoor chairs). I would love to see you climb mountains!
Keep up the good work and thanks again. Wolter (Haren, The Netherlands). P.S. Please don't feel any pressure to make videos, your are doing great, your fun and playing the way you do now gives positive energy to many!
i wouldn't have guessed it would have a plastic gear. All the motors i have use a brass gear the worm runs onto. I love using wheelchair motors they are super high quality. ive made 2 rc lawnmowers with them and just finished retrofitting a mini bulldozer to run on battery.... i wish everything was built as nice as these motors
Ive been a tech for 16 years. Permobils motors are the best in my opinion. They almost never fail.
I had to watch this video again. you really seem to have an endless pool of knowledge. I might be able to pull that apart...but I'm not sure it would still function when I was done hahaha. I've been kind of lucky with stuff like that (broken screws, crossed threads, etc). Hand the broken item off to a machinist and it comes back with a short story....oh, no problem, I just used an easy-out . or I just drilled out the screw and chased the threads with a 10-24 tap.... Then I think back to shop class in high school and my inside voice says "YEAH RITE !!! it was just that easy".
yea - RE the broken bolts.. apparently they intentionally use soft metal "screws" and PERMANENT thread locker to mate the motor to gearbox. provides a shear point, or planned failure mode - kinda like breaking a U-joint in your truck, instead of shearing off the input shaft on the rear differential haha.
permo peeps said -"Don't expect to take a motor off of a gearbox without breaking bolts!"
4:34 take all screws out by heating up de metal, redrill the others, save the motor.
normally that's what could be done.. but these motors are pretty sensitive to heat. there's no way to use a torch, or otherwise without setting fire to/melting the nearby components. the screws are intended to break for uninstallation. if it was going to be re-used, the broken parts can be pulled out, and threads cleaned up. this motor has bad windings however. that why i used it for this video :^)
Excelent my Friends
SUPER EDUCATIONAL VIDEO! Everything covered and in detail. I have 3 wheelchairs, 1 is really Heavy Duty, and the others are regular duty. I have plans to use the motor(s) on a 3 Wheel bicyclic.
24v which I also have 24v Solar Panel to Supplement the Charge of the batteries.
i actually made a trike conversion thing a while back.. BUT i used bicycle chains to drive it, and the gear ratios i picked, the chain couldn't hold up to the torque haha! i think hub motors are the way to go! use one in the front wheel, and youre done!
I made an electric 2 wheel bicycle when i was younger using a wheelchair motor. Drove the pedals with the motor so I could use the gear ratios. Bug mistake. Nearly broke my leg when the motor kicked the pedal around and hit my ankle! Chain had slipped loose of the back end and the motor suddenly gained a lot of speed, couldnt move quick enough. Whatever you do, be careful!
Damn, I was going to make an offer on the table and the broken bits of screws!!!!! 🤪🙃🤪
Thanks a lot for this video, I have been trying to work out what's wrong with my wife's electric wheelchair motor before taking it apart and your video gave me the answer just by seeing what's inside.. I think we will just wait until she gets her new wheelchair.. eventually.. I'd love to see more videos like this, it was very interesting.
awesome - glad it helped!
The battery of the chair needs to be shipped quickly and a new one. I do not know where the problem is. One of them said that it is possible that there is a short circuit that causes a decrease in the battery charge. It does not receive electricity for more than one and a half hours. The chair moves approximately 1 kilometer
very good video ,
Just opened invacare tdx sp2 SSD motor , using angle grinder just splitted whole thing in half to have better view
Thank you very much. The best review on youtube. Next episode we expect some Quickie motor to dismantle :)
kidna funny.. i WAS going to take apart some quantum motors but then i saw this permobil one lying on the workbench! the gearboxes on other brands aren't nearly as nice... will be interesting though to do at some point!
Hey great video...
Hi, thanks for the video, I really liked it. Have you ever disassembly 4-pole Pride hammer motor?
I am trying to revive a Jazzy 1121 chair. it keeps making a clicking noise whenever i hit the 70 amp controller, just clicks and doesn't move at all. I noticed the underside of both motors are covered in oil. Installed new batteries and cleaned male and female 9 pin connectors. Connectors in female side of the 9 pin connector, have proper amount of physical resistance. I removed the motor/gearbox assembly. It was 102 degrees in my workspace and full humidity. I've had enough for today. I may get rid of the 9 pin connector and just hard wire it, thus bypassing rusty, corroded, unseen areas. I'm going to rehydrate and sleep on it and make a decision tomorrow.
A lot of the engineering plastics are self lubricating and exceptionally strong, often stronger weight for strength than many metals. They should last the lifetime of the motor.
I’d love to see what’s in an Invacare GB motor. But it would hurt to see you take one apart because I need a right GB motor. Plus they must be in demand since they discontinued them. Their selling for hundreds on eBay.
yea.. and I still haven't had a chair with them either!!
BTW i was able to drill, and use an EZ out to remove those broken bolts on the motor housing! were back in business!
ever try 48 volt using used Nissan leaf battery bet you could get more range
I have over 6300 miles on my M300 motors and a couple of weeks ago one of the brushes finally gave out
NICE!! thats impressive!! did it stop moving, or let the smoke outta the box or anything?
Thanks for the great video! The lube for the gear reducer is on the label on the side, I believe, long with the ratio, and maybe the torque rating (scratched up?)....interesting! Those chairs cost $35K? How would you remove the bearing(s) either from the gear box or of the motor or armature, if you happen to know? Thank you for showing all you did!
thanks!
I'd assume some sort of press.. or maybe a small brass mallet.. never removed the bearings - maybe they just fall out easily? lol haven't been able to find any specs on the load ratings etc.. they don't usually stamp these things for some reason. would be nice for those of us that want to rebuild things instead of replacing!
Totally Normal then, how would they make their $$$$ lol 😏
You wouldn't know where to get new brushings for a Permobil M3?
Do you have told motor parts?
I rebuild them to give away to people that need 0 turn chair
5 minutes 30 that's what I pulled out 😆😆😆🤦♂️ NOOOOOO🤦♂️
great video...just took my daughters old wheelchair apart..i would like to use the motor to make a sliding gate...any idea howto do it..thanx
Hey man, if youre still interested, just remove the motor lock, and the motor itself runs off 24v. I would recommend a couple of small UPS batteries wired in series for 24v, use the original tire as friction against the ground, and then you run the voltage red wire to +24v black wire to -0 v to go one direction, and just reverse the 2 wires to go the other direction. If you want a controller, thats a bigger topic.
Hi )) How do i adjust the brakes on those motors ? i apply neutral but the brakes click the solenoid and take to long for the chair to stop ? it used to be nearly right away but over time it got worse and worse , thank you )) Also just got an Magic Mobility X8 for fishing in the highlands of Tasmania Your thoughts on them ?
Oh no the screw broke on you 🤦♂️
Great Video Dan! would love to see a gear-less/bruhless. Have Yet To Come Across One That Dont Care About Wrecking. Ive Learned About Green thread lock after Wrecking a couple of my own motors.
Good video. At least I know where the oil leak will most likely be coming from on my Puma 40 but unfortunately I still haven't found the answer as to why my Salsa M2 brakes sharply (as is required) but my new Q500M rolls for a while before stopping which makes using it in central London very problematic.
there's a setting in the programming called 'forward deceleration' that should help... requires a handheld programmer to change though... OR is it coming almost to a stop, then there's a delay before the brakes actually click on?
@@TotallyNormal- The holding or parking brakes (as shown in the video) engage normally once the chair finally comes to a rest. I suspected that the problem could be in the programming but I have no idea how to even get hold of a wheelchair programmer, let alone how to do it as I usually limit myself to mechanical issues only. I once had a technician make some adjustments to the VR2 ECU on my old Salsa and he did it through a program on his PC; although I would imagine 'end users' aren't trusted enough to do it themselves. I once had an Invacare Storm 4 X-plore with Tru-Track motors, an amazing wheelchair, however, Invacare in the UK refuse to supply parts outside of their dealer network and dealers, of course, refuse to sell parts without service.
Thanks for your reply, at least I have a name for the matter now, forward deceleration, I'll try to figure out how to go about altering the settings. Thanks again.
i think the Q500m has R-net controls..? thats the closest setting to it..BUT the VR2 stuff has a specific setting for the time before applying the brakes.. R-Net however doesn't have a specific delay setting for 'holding brake' engagement...does your chair slow down fairly gradually when ya let go of the joystick? the brake engagement is baked into the setting for deceleration.. it slows the chair with the motors, then after ya get close to stopping it clamps them on. (pretty sure it uses current monitoring to determine when you're actually stopped) so i think making it 'stop faster - or decelerate faster' should net the same end result of them turning on sooner.
@@TotallyNormal- The problem isn't the time taken for the holding brakes to be applied but the length of time it takes for the chair to decelerate and come to a stop after the joystick is released. On the Salsa it's fairly quick to slow down and stop upon release of the joystick (and then the holding brakes click on), of course, if I put the joystick in reverse (on the Salsa) it comes to a halt even quicker, thereby avoiding collisions with pedestrians or getting squashed by cycling extremists. But on the Q500M even after the joystick is released it rolls to a halt quite slowly; putting the joystick into reverse makes no difference and it still continues to roll for 3 to 4 feet, then once it stops the holding brakes come on. What I want to do is reduce the time it takes for the chair to initially stop.
Incidentally, the Q500M is available with VR2 or R-NET, I don't know which my chair has but I suspect that it's the VR2 as this chair appears to have 2 pole motors although Sunrise claims to supply it with 4 pole motors. I'm basing this on my newly acquired knowledge from the video that two brushes is two pole and the Sunrise website shows a Q500M with motors having four brushes, two more than mine!
I'll take a look tomorrow to see exactly which controller has been fitted.
ah! ok then yes - the deceleration setting is what ya need then! make sure that they change the setting for forward AND reverse! 2 separate settings! yea that's not safe!! also does the E-stop mode work on the chair? if you need to slow down quickly, pulling joystick in the opposite direction briefly activates a higher power braking mode.. (dont worry its not bad for the motors).. its actually a secondary setting called "hard braking rate"
I've purchased another rascal pioneer it's solid but the speed is restricted and only going 6 mph can you tell me what's restricted it I've checked tires everything. My old rascal went upto 16mph but the axcel broke...It come like that should I switch the motherboard inside?
hello good afternoon! I'm Brazilian and I really need information. I use a motorized wheelchair, model Millenium C from the Freedom brand. If you google it you will see which wheelchair I am talking about. This wheelchair is imported and assembled in Brazil and sold by the Freedom brand. I need to know what model of wheelchair is sold abroad. I will be very grateful for your help.
An old Rhapsody power chair goes for a foot or two, then quits. What could be the problem with the motor?
Trying to make a gocart with two wheelchair motors. Looking for electronic speed controller. Any products you can recommend? Looking for tank style control. Each back wheel has one motor and controller.
youll need something that supports differential thrust, or vector steering.. there's dual motor ESC's out there for it! or some ESC units can link together. im actually looking for a couple myself.. but havent bought anything just yet..
I’m trying to upgrade a quickie pulse 6 to add some speed I’d like any advice
Wondering why my Pronto M91 drips what looks to be grease occasionally. Is there a convenient way to resolve this? Thanks Doug
there's a seal between the gearbox, and the motor - those can go bad.. theres another video ya can skip around thru - i replaced that seal in a different chair :^) th-cam.com/video/F9kt9PG911Q/w-d-xo.html
Of course that gear is made from plastic. Just not a cheap plastic (one would hope). Plastic is simply "a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc., that can be molded into shape while soft and then set into a rigid or slightly elastic form." Thanks for making that video.
turns out its Delron! a SUPER durable composite :^)
@@TotallyNormal- - Probably Delrin actually. DuPont's trade name for polyoxymethylene, a synthetic polymer. AKA, plastic! Strong stuff with low coefficient of friction and great for injection-molding gears. :)
Btw, I’m planning on riding a mobility cart “Across Florida” from Tampa to Daytona Beach...
sweet! when ya planning on doing this??
Better mount a large solar panel on it I used a 48vdc section of a Chevy volt battery and split it paralleled it and I only get 24 miles of range with 94ahr
where can i get the brushes for a motor right /left for a mvp5 and the name and where i can get them
ok, so they're using an O ring to seal up the gear box instead of a gasket? Cuz I saw that cast aluminum and thought to myself, well they have the bottom is metal and the top is metal and it's got gear oil in there so they're probably using a gasket between them but I didn't see one when Dan opened it up....Interesting....Question though, how do you know how much gear oil to put back in there once you've opened it up? Just wondering...
you can see the O-ring flush mounted into the top half of the lid.
thats easy! dont spill it and ya wont have to put any back in! LOL
seriously though.. usually 1/3 to just under 1/2 full is how most gearboxes need to be
I really liked the part you do it so we don't have to. LOL.. You have to keep a sense of humor or life can turn your guts into knots.
Nice video! First, between a 6 and and an 8 (or 6.5/8.5) motor package on most chairs - What's the difference, usually? Motor? Gearbox? Both? Second, how hard would it be to mod the 6.5 motors into the 8.5 MPH package, unofficially? I've seen Burgerman's 15 MPH BM3 custom chair, but that's just too much, especially since I'm no engineer, nor do we in the US get lump sum amounts like him to buy/build our own chairs.
hey hey! its *usually * the gearboxes that are different.. ive chatted with at least one person that's swapped gearboxes over from a different motor set.. haven't tried it myself at this point. in the case of the older quantums, (6000z) the motors also appear to be different as well as the gearboxes. but larger tires.. thatll get ya more speed! - of course causes other problems.. like the geometry of the front and rear castor wheels.. and the suspension getting all weird. but yea,.. once you get over 7.5 or 8 mph.. its a whole different world!
Thanks. Such mods are beyond me at the moment, as I don't even have a spare chair, but it's nice to know. Also, I wouldn't take Quantum's gear as much of an example on anything, their chairs are cheap crap. I can't name anyone I know that's specifically chosen their chairs, especially the higher end models, and been happy with the quality.
yea.. LOL mostly they're just REALLY HEAVY haha
I'm on my second set of motors on my F3 as they warm up they start clicking really loudly. What is the clicking that I'm hearing and why is it keep happening?
Any idea why wheelchair motors (particularly the faster ones - 6mph plus) sometimes bump or judder?
It can happen as wheelchair motors get older. The brushes he showed are a wearing item and get shorter over time. When they get short enough the spring does not push them hard enough against the armature, and they can bounce which makes the motor lose power, and therefore speed.
You mentioned the price for one of these wheelchairs. Was it a slip of the tongue when you said they cost $35000?
rehab chairs are expensive!
I have a action track wheelchair have u worked on them?
Hi. Great video. Thank you. I'm here as I took the motor off my Westminster as had a breakdown caused by a brush breaking inside. I took it all apart cleaned all the carbon out, replaced everything, put it back on and now it's running in reverse!! Help. 😊 What have I done wrong and is there a way I can rectify it? Many thanks.
if the brush housing gets put back in in the wrong orientation that can happen! (usually 1/4 to 1/2 turn off)
@@TotallyNormal- thank you. Took it all off turned it half a turn and hey presto. Thank you.
AWESOME!!
Hi, What is the name and brand of this grease you are using to lubricate the gearbox? Thank you!
its whatever permobil loaded in there from the factory :^) i just tried not to spill too much of it lol
@@TotallyNormal-, Thank you so much. I have a permobil c-300 and i was in doubt which grace i should use in the gearbox! I bought it in 2008 and never oiled it! I make little use of it too! Thanks again!
@@TotallyNormal- I'm written on your TH-cam channel!
Highly Appreciated learned a lot ....... Is there any way i could get my chair go any Faster ?????
programming is the only thing - but it wont usually get ya much.. typically its mechanical limitations that set the top speed. ...bigger diameter tires maybe.. but then that kinda throws off the geometry of the chair.. aftermarket motor controllers.. but that's a whole big deal.. if the brand / model of chair has a high speed motor option.. sometimes ya can find used high speed motors on ebay. the difference is the gearing typically.
@@TotallyNormal- Thank you so much bro your reply means a lot to me.... And you're videos have already helped me lot in resolving my wheelchair problems 😘😘😘 Thanks Once again......
Do the manufacturer use grease inside the motor? yes I also took my stuck motor apart 😀😉
depends on the brand.. they all use something different - i just try and identify what was inside the gearbox, and use the same when putting back together
@Totally Normal Maybe you can help me. I think I may need a new motor. Recently I'm noticing if I want to go straight, I'm having more and more to favor the joystick to the left. Can you tell me which motor is going bad left of right? My guess is the right side (as I'm sitting in the chair). But I'm not absolutely sure if that's correct. Thanks!
What brand/model of chair do you have? Pushing to the left means usually means the right motor isn’t turning as fast as it needs to. Have ya checked the brush housings for excess debris? (And brush wear)
@@TotallyNormal- Thanks for the response. I have a Jazzy Elite HD. Motor code# end in 11 and 12. I forgot which is left and right (you probably know). I'll check the brushes first ( making sure to keep the same orientation, as you mentioned in your video). And if that checks out O.K. then I'll need to pull the motor and dismantle and clean it? I use this chair as my workhorse to do garden and yardwork and I can say the motors have gotten really cruddy at times.
cool
do you have experience with dimantling the magnetic brakes and can you instead simulate an electronic equivalent load in the electronics ?
yes! i did that once with an old invacare chair.. used a few 3 watt resistors, and a cooling fan to simulate the load :^)
@@TotallyNormal- can you tell me please deatails , we want also make so with storm 3 10km/h
i looked at the sticker on the side of the brake modules, and also you need to determine the voltage they operate on (some are 12volts and others 24v - usually also printed somewhere on the sticker) they can be different voltage between models on the same brand as well.. then you measure the resistance of the coils, do some math, and you have your resistor values! i dont remember the equation right off.. BUT they WILL get hot! i mounted mine on a metal plate with a cooling fan... send me a DM on twitter and i'll see if i can dig up the details. ya can also use the email submission form on the website (brokenwheelchairs.com) replies will take a bit though.. im in the middle of moving
I need brushes for my jazzy 614HD pride doesn’t list them seperatly they have merIts motors
aside from having custom brushes made (insanely expensive) i haven't been able to find a supplier for motor brushes :^/ i usually just get whole 'new' motors from ebay or whatnot...
I would put money on the manufacturer used crappy metal for those bolts to get their cost down as much as possible for a number of years the Chinese were famous for using a Powdered metal it was pure crap with very little strength at all okay for cases and housings but not for nuts and bolts thanks for all the details you know and shared in this video m onmy 7th or 8th mobility chair and I just like learning as much as I can
At least the lady came after you were done ll...
What is the rated power of motor??
I've got a Permobil C500 ESP. It's a used chair I purchased. I'm having a problem. All the seat functions work but there is times my seat tilt doesn't work. Never had any problem with the leg lift, the seat elevator, or the back going down. Usually if it stops working during the day by the next morning it works again. It's getting more often that it doesn't work. Any thoughts on what might be my problem? Thanks in advance
do any red lights flash on the seating buttons when it happens? also have you tried using the mode button on joystick, and operating the seat functions via the joystick directly to see if it works that way?
On this chair everything works off the joystick. There's a on/off switch and another switch you push when you want to adjust the seat. When you hit the switch for the seat functions you move the joystick sideways to get the the seat function you want then move the joystick forward or backwards to adjust the seat. When the recline quits working if I hold the joystick sideways trying to get it to work the lights will start blinking. When I move the joystick back to the center position the lights stop blinking.
I meant to say is when the recline stops working when I move the joystick forward and backwards the lights blink not sideways.
oh - so theres no separate buttons for the seating controls right below the joystick?
No there isn't.
Hi Dan l have a permobil f5 vs has 4 pole motor wheelchait its very smooth powerful for my back up chair l am thinking of getting permobil m3 wheelchair basically same as m3 they have 2 pole motor l was wondering when you compare f5 and f3 or m3 is the power similar as l havnt used a 2 pole motor f3 if you can help me would appreciate it thanks.
the motors on the 5 series chairs are about 2x more powerful - BUT the F3 isnt lacking on power :^)
Thanks mate .
Just a question, I recently purchased a WHILL Ci and really like the way it handles, unfortunately the electric brake clicks rather loudly and bothers my wife, I’d really like to stay married so is there any simple way to minimize the clacking noise. Thanks..love your videos..a new subscriber.
hey hey!! well.. i haven't seen a whill in person yet and have no idea what mystical magic makes it move... theres usually a way to make most controllers ignore the brakes.. BUT its total unknown for me on that chair.. as far as making it quieter.... the brake coils get hot, so ya cant really try insulating them.. sooooo short answer... i dunno *shrugs* id like to check one out at some point! they seem neat!
Totally Normal thanks for the quick response, it’s still under warranty for a year so I really don’t want to be too radical at this time. I wanted to get the electrical schematic, but they only sell those to the retailers. Hopefully in the future someone will post a TH-cam on the innards of this chair. Thanks for taking the time to do your instructional videos. I’ve learnt quite a bit.
Hey there, i did a mod for the invacare motor locks when they switched to a big metal disc with a lever on it probably 5 years ago? I removed the brake release lever and 3d printed a plastic one. This eliminated over 1/2 of the noise. The lever itself was acting as a sound amplifier. Making it out of plastic deadened the sound.
Thanks for the idea. I don’t have access to a 3d printer but it’s an interesting concept. BTW still married..lol
i need a replacement for DL 5.2i DL50UBR12 JOYSTICK. do you know what the best source for it? i appreciate your help
what brand/type of chair is that on?
One question, why do we need an electromagnetic brake while the worm gearbox is self-locking?
you'd think the worm gear locks things.. but it doesn't. ever put your chair in "neutral" and push it around? that's the motors and gears turning :^)
@@TotallyNormal-thanks, Actually I am designing an electrical wheelchair using worm gear motor and have doubt if electromagnetic brake is really necessary.
in this application it certainly is required! but with the right design it could be eliminated im sure :^)
I pulled my old rascal mother apart never again will I do it I couldn't get the long screws back in and was in repair a while 😆 £350 I payed but it was already broken...
6 MPH is standard for a lot of those scooters... a lot of times thats the mechanical limits of the motor itself.. but i havent played around with many of the scooters - most of what i know is only rehab chairs... short answer.. not sure :^/ BUT motors will run on whatever voltage ya feed them! lol more volts = MOAR SPEED!
@@TotallyNormal- Aaaw thankyou 😉☺️ I won't be attempting opening the motor this time 😆
You could have heated the screws probrably would have saved you
Wow nothing for sale? She wacked
Now, how can i make it faster
Makarta gear
You should invent a quiet electric brake. For museums, libraries, nature watching, churches, funerals and other venues that the clicking sound is annoying...
once the supply chain issues settle down, ill be showing a chair with silent brakes :^)
M3 or M300 motor?
same motor works in both chairs :^) i got this one on a pallet of parts
Thanks. Very informative, and entertaining, video. Very interesting to see what we're sitting on. I'll have more respect for my chair now :)
I would bet the big gear is nylon.
Great video! any chance of an email address for advice?
there is contact info info the video description :^)
@@TotallyNormal- thanks: guess i am too old to understand that what came to my email has a twitter icon and i am not set up to do that...email and facebook i have some experience with...but not twitter

You should tell that old bird to keep her nose out of your business.
Motor making noises
Are you. Live 1215
Note to self do not buy a Permobil.
That’s Interesting takeaway…lol these are one of the best designed motors I’ve seen!
My friend tell that woman for me. Go mind your own business
