I just came back to this video as a lot of people have been asking me "do you need to balance the can after you do this?" The short answer is no, you dont. The longer answer is as long as you were careful to avoid any gaps and you smoothed it out afterwards you do not need to balance the can. Obviously, if it was easy to balance afterwards we would do it, but in reality it makes little to no difference. This method and the liquid epoxy method has been done on many motors and has proved to be a good reliable way of battle hardening. Some manufacturers have started to battle harden in the factory which is a great selling point, and as an esk8 community we welcome that development!
Hey bro, thanks for the vid. I'm pretty keen to find out how this lasts long term. Have you kept and ridden these motors lots? Would love to see if any has chipped out etc from vibration or shock over time

Great video brotha! Always wanted to do one like this as I have 2 motors with magnets that need reattaching. LOL, but for some reason your narration had my head in the gutter. Take care my friend!
A much appreciated education on brushless motors, Lee. Know I finally know what a Hall Sensor is! I read on Reddit just a few hours ago that another disadvantage of brush motors is letting up on the accelerator is like applying the brakes, not slamming on the brakes, just enough to create more drag then you would certainly like. Don't know if that's true, but it is interesting. That motor puller is brilliant. I have read of people having problems changing hub motors and rear wheels on the Meepo NLS Pro because of the powerful magnetic force. I am sort of dreading the day I have to do it. Something like your invention would be perfect! No skating here, as we received 15-20 cm of snow on Easter Sunday.
No problems David! You are welcome! I didnt know that about brushed motors but can see how that is possibly true actually. Everyday is a school day mate! Shame about the snow, I've stopped riding full stop because of Covid 19,.not worth injuring myself at the moment. Hope you are well mate
I'm trying to build my own motor and i want to know if the gap between the magnets is the same as the gap between the motor stator slots or no these would help me a lot also thank you for the impressive demonstration and your informative videos
@@LeeWright Not that I know of... the problems that the motors incur is bearing seizure, which then leads to the axle being chewed away. At that point, the magnets would get scraped from misalignment. At which point...you have to submit yourself to Bid Daddy Future Motion. Motor replacements are usually about $600ish. Some folks just open up the motor and put in better bearings to avoid that whole scenario.
Lee Wright Yeah... Burris Racing has ceramics that people seem to like, and SKF are used also, but they're very expensive. Future Motion are... Very interesting with how they do things. Many riders can't stand them, and I don't blame them. Most their parts are made in house, including their motors still I believe. But they make sure that the repairs of their boards are also profitable. It's the main thing that makes me look either back at Eskate, or to getting an EUC.
Nice one mate! Very interesting video. I did not know you have broken your arm mate... glad that you are all healed up. Are you planning on putting the mesh around the vents to stop any particles from getting in?
@@LeeWright So sorry to hear that.... esk8 fall ? I knew quite a few people ( in my young boxing days) who did break hands and they were using a tennis ball with a small hole in it to train the hand ( squeezing the ball ). An idea for you online shop, plus i would need one so will order :) Could you please design and make available a cell holder for 21700 cells? Need one for my new battery build for when i spot weld and solder. Thanks mate!
Love it mate - class as always! Question, When protecting the stator, is there a reason not to just protect all of it? Would it cause a ventilation issue? Thanks bro! This is going to be my next project! Ordering miliput now!
Hi lee 😁 thanks for the great video. I just got a set of turnigy sk8 6374 and drilled 4 5mm holes in the end cover (to make vented like yours) put in screen to cover holes then battle hardened with epoxy putty. That set in 25 min. Had huge blister on end of finger 🤣🤯😉 anyways i ended up with some putty on magnets. Nothing over .5mm thick. Motor turns freely. Do you think a thin coating over magnets will hurt performance? Should i sand off all on magnets before putting together? I am very happy with them as is, i just don't want to get them together and have them weak or something 😉 replacing the maytech motors i put on my newbee drives. Those suckers overheat in 4 mi ☹️ will save those for winter 😉
Great tutorial Lee! I have been wanting to try this for a while now and seeing it done in a video makes me feel way more confident about undertaking the process myself. One thing I am curious about; do you think that protecting the hall sensor PCB with epoxy putty has thrown off the balance at all? I am thinking about using a donut of putty on that end to try to keep the weight evenly distributed.
Great video , I had a prob recently with a direct drive board ,it lasted 5 mins before something was obviously wrong with one motor ! Well I pulled it apart to find on the rotor (can) a couple of magnets had started flaking or chipping away ? Sending metal into the motor,maybe the electro plating was breaking down? Secondly the magnet spacing was not even with just on large gap in in the placement around the rotor Maybe 4 mm bye a guess , what’s your opinion on this , at the moment I’m in the opinion that I’m going to un glue all the magnets & reglue them with even spacing , but I’m worried about the damage to the 2 magnets ?
Hmmmm tricky. I think it sounds like those are cheap magnets and construction but I guess replacing isnt an option. I think you are right to sort the spacing out and then battle harden them so they cant move again. More temps will increase, but if you can live with that I would do it
@@byroncornuel4101 I dont bro, plus you could easily change the kv of the motor by putting different strength magnets in - if I were you I'd glue the standard ones in and then battle harden
Hey Lee wats your experience with filament for 3d Printers. Wat da best to use, ABS, flexible etc. I'm jst getting into 3d printing for my DIY esk8 projects and drones.
I've printed quite a few bits in PLA+ but for esk8 this is far to brittle. I've only just started attempting to print ABS & it's a bit of a nightmare! I have a CR10S & the ABS doesn't like sticking to the build plate & it tends to warp. :( Gonna buy some PETG if it's OK to use on the CR10S & give it a go! Thanks for bringing this up/the suggestion, I kinda forgot PETG existed! :]
A quick question, you've only covered sections off the rotor, wouldn't that potentially cause imbalance and increase vibrations? I'm a total newbie to this so I could be talking hogwash. :D
@@ErnestRamos the rotor does spin, that's why it's called to rotor! I think you mean the stator? The bit I did second? That doesnt spin so all good. I should have mentioned that
@@LeeWright Yeah my noobness is mixing the names of the parts up now. :D Basically the center part where the PCB is (part 2 of the hardening processes). Eventually I hope to build my own mountainboard and your channel and build videos have been most informative. :D
@@LeeWright actually i think i saw u mention it in another video! Ah well ay, we take the risk each time we go out! Wanna be a weapon you will take some damage eventually 😁 Get well friend ✌
@@LeeWright so long as youre alive & not crippled we're smiles ay! 😁 I had a similar incident couple month back. Silly jump led to majorly sprained ankle. Was off for 2 month about. Had done the jump already bout 20 times so figured 1 more cant hurt. 2 guys were standing on top i yelled at them to both move aside i flew between them in a twist n land front wheel first. Yep.. embarrassing lol.
Cool video Lee! A couple quick questions: Do you feel that hardening the rotor magnets alone is sufficient for esk8? I know traditionally battle hardening involves epoxy in between the magnets on the stator as well. Also, do you know what it means when a company says their motors are "factory hardened"?
I don't actually know the answer to your first question. I've never had an issue with a motor myself and this is my first time hardening. When the factories say it they mean they have put epoxy in between the magnets, I dont think they go any further than that.
Having to do something like this never even crossed my mind, thanks for another great/useful video Lee! I assume that not all motors will need this process? I.E dedicated motors for esk8 such as Torquboards etc or am I wrong? Guess I need to do some more research... Are you able to suggest any specific motors that will be a good buy here in the UK for a Trampa build? (It's been years since checking out this stuff myself - I need to get back in the esk8 zone! lol)
I attempted this method and let the putty dry before I put them back together and I don't have free movement anymore , I am sure the error was my own. I cant spin either motor and now I cant get the can off of either of them Im considering getting a pipe wrench with a chain to get the leverage to force the movement. Do you have any ideas?
‘You get a feel for the size of sausage you need’ 😂 sorry but I find the smut in everything hahaha I wish you were my cdt/electronics teacher years ago.
Great techniques, thank you for everything! :) I hope your hand will heal quickly! I know that it is good to protect the magnets, but on the rotor it can also make the motor unbalanced :S I am not sure if they balance the rotor part at all. Or is it too slow to care about that? What is the difference between the V1 and V2 other than they changed the color and the 10 mm shaft to an 8 mm? Also the cooling is a bit different because in the V1 those ribs are thinner. Can you please measure the length of the shaft on the APS V2? It looks like that the V2 have a longer one by a few mm. That would be great if you could share some info about the new motors. :)) At least the brand or the KV specs P:
Hey bro, I told you the brand and kv specs, APS 170kv. Yeah looks like they turned the shaft down to 8mm on the outside, there is a step down in the shaft outside the motor. The protruding shaft length is 30mm. I dont think they balance them and I dont think I made it out of balance, the application is pretty consistent
I don't think the motor includes a thermistor. I've watched the data lines on an oscilloscope and there are three lines which go high and low (kind of like a quadrature encoder but with three lines instead of two) and the other two lines are to power the encoder. There isn't a temperature line.
@@LeeWright I'm not so sure about the temperature sensor now. The motor I looked at with an oscilloscope had five wires. The new skateboard motors I have include a 6-wire sensor lead. Apparently the extra wire is the temperature sensor. I've used brushless motors on robots in the past. I'm new to making my own e-skateboard. I'll try to figure out how the temperature sensor works and update this comment.
@@ddegn Is it possible to add a sensor externally or is it losing the sense that way? I am ordered a V2 now with a closed end cap and I am worried a bit of the temps.
@@hunelektroBF I wouldn't trust any external temp sensor. If you've only got 5 sense wires I'd bet good money there's no temp sensor. Really weird coming from an ebike hub motor background and seeing these motors ship so bare bones.
