- In this video I show different servo motors which I have. One of them is very powerful (3kg.m), but it has a very high backlash. Still it is very nice actuator for its low price.

CAN U DO SOMETHING ABOUT THE SPEC REQUIRED FOR A ROBOTIC ARM
please how to control super 300 servo with arduino?
Where can i buy the D50024MG SERVO OR its best alternatives
You all probably dont care but does anyone know a way to get back into an instagram account..?
I was dumb lost my account password. I would appreciate any tips you can offer me
Awesome job explaining, and showing the inside of the servo motor
Thank you for your great explanation 👍🏻
Wow! that super 300 is really a monster! A very beautiful monster! Thank's for this video, you know, you are the boss!!!
Always looking forward for your videos. Thanks!
Thank you for inspiring comment!
this is great, thanks for info.
And your excellent methodology continues. Thank you.
Thank you very much for always kind and inspiring comments!
Your videos are awesome! Thanks for sharing such knowledge with us
Thank you for your kind comment!
I like ur explanations coz they ate so real and applicable
Thank you! Just a note though: Torque is measured in kg.m or kg.cm in these examples. These should be read as “Kilogram Meters” or “Kilogram Centimeters” - not “Kilograms PER Meter” or “Kilograms PER Centimeter”, which would imply kg/m or kg/cm (measures of linear density).
Very informative video, like all your videos! Thank you. The end was funny 😀😀
New subscriber.🔔 This is a great Channel and your topics are on point for what I want to learn about. Thanks!👍
Thank you taking that apart. 👍🏻
Thank you for your comment!

Great stuff as always!
I love your videos. You teach us a lot. Thank you so much.
Thank you for this inspiring comment!
Your videos are awesome and so informative! keep it up
Thank you!
THANKS, MAN FOR ALL THE INFOS
Thank you for your comment!
Your video helped me a lot
Beautiful review 👍 Thanks
Thank you! And thank you for your comment.
interesting, I think I'm more impressed with the open source 3D printed assemblies now I've seen what's in the commercial servos, would be neat if they can be bought pre-made, either printed, or injection molded, or cnc, especially if you could get them with precision made metal gears
you should do a video on that huge rc servo motor... ;)
Your videos are great! Could you talk about serial bus servos? There are some Dynamixel clones like LX16A or some Feetech servos with magnetic encoders and RS485 that look quite interesting for the price point.
It would be great if you could test the torque of each servo to determine if the rated torque is accurate. I often find these are rated much higher than they can achieve
Your video is hard working effort
NICE!👍👍👍
I very like your channel.
Thank your for this nice video. Best servos in Market are made by Futaba I think (brushless, backlash...). They also have +30kg Servos. I you use two servos for one axis (left side, right side), I think you can preload the servos, to reduce backlash and double the torque. Savox is a low cost alternative. I made a lot with servos in past. I would ask the futaba support, maybee they can provide more data. Best regards
thank u
Hi sir; thank you very much for you work; we need more videos about servo motors torque test for these servos.
and why is the written torque is different from the actual?
I've recently subscribed to Your channel and so far I love it.
I'm so looking forward for your new reducer design! Can You tell us just a little bit about it? What will be reduction ratio? Will it be 3D printed or machined? Planetary or other type?
Thank you for kind words! The first version would be 3D printed, and I will see if this would be enough or if I should use aluminum. The reduction ratio will be somewhere from 30 to 90. The type: mix of planetary drive and cable system. I hope it will have a good performance.
Watching this wonderful video here four years after. At 9:41 Is it just me or does that Super 300 has a plastic gear right after the motor itself?
Is that perhaps to protect the motor itself by letting the plastic gear to break when overloaded?
If you look for decent power servo on PWM with top quality you can try Futaba HPS series like HPS-CB700. It is expensive but worth the price. It comes in two wariants fast one but weaker and more powerful but slower (still quite fast). The torque is 50kg/cm and 70 kg/cm. They are standard size servos.
excellent demostration,
please, can someone tell me what small servo is the noiseless?
Nice review never new there was such a big servo. Very interesting do you have a link for that monster? I’d like too tear into one 🤓
Thanks, informative as always, learning a lot.
Do you want to use servo in base joint of an arm? Or last joint (aka "hand")
Thank you for your comment. I for the future robotic arm I plan to build the joint by myself, using the brushless motor.
I found this big servo very interesting: it is powerful and cheap (70 USD). Thus I decided to buy it and to test it. Two main disadvantages of this servo is high backlash and absence of bearings (which will reduce the life time).
holly cow .thats a stump pulling servo.
This is a very interesting video. I had no idea you could buy such big servo's. The big one is only $66 so that gives us great options. I think you can make it even stronger by changing the motor to a bigger one from a drill. IKEA sells really cheap cordless drills which are quite powerful. Combine that with the magnetic position sensor and you have a great setup for a robot arm.
This is very interesting idea! I should really consider this. It is cheap and probably powerful! Thank you a lot for this idea! I will check this!
@@Skyentific Backlash is a problem though... These drills have a lot of it. But a robot arm also needs a brake to keep things in place when you don't need to move it. So I think if you combine it with a brake it should be ok. It will be tricky though to release the brake at the right moment. Basically combine it with the slow start of the motor. When the motor spins up, gently release the brake at the same time.
Hello,
thank you very much for this video. I recently bought the 500 kg variant and have a problem which I have also seen in your video. The end positions and the neutral position are approached only very slowly (As steering hardly usable) Do you have a solution for this?
so, servo motor is basically just 'normal' DC motor but what makes them 'servo' is a closed-loop system?
The encoder! It gives the feedback about the output shaft position. Thanks to this feedback the servo can precisely move from one position to another.
@@Skyentific i wonder is there any servo but with stepper type motor instead of typical brushed DC motor ?
@@IlhamDefraN using a closed loop system on the stepper motor to measure relative rotation isn't very useful because the stepper motor moves at constant angles per step, but a sensor for calibrating the absolute position of the axis in for example a robot arm would be useful. that's an application problem though and not something that would be included in a motor, so if you wanted something like that you'd most likely have to do it yourself with an external encoder.
@@crazywazy5527 it's common when steppers skip under high load or during acceleration over resonance frequency band etc. When you need accuracy, you need feedback.
@@IlhamDefraN yes it's called "closed loop stepper motoro". There are quite a few systems on the market.
That last servo is a bit of a puzzle. No bearings makes it seem cheaply made but using a magnetic encoder is a huge plus. I wouldn't have thought they'd use a magnetic encoder on a servo without bearing.
My main complaint about most servos is the pots most of them use. Most (all?) servo pots wear out with a lot of use. The pots are usually fine when used in airplanes which are used occasionally but pots in robot servos can be a huge problem. When the pot starts to wear out it makes the servo start to jitter around worn out section of the pot. Once this jitter starts, it makes the problem much worse very quickly since the jitter increases the wear on the pot. I have several hexapod with lots of servos and I have to replace the servos every so often. A magnetic encoder instead of a pot makes a servo last much longer than normal servos.
Here's a link to one of these hexapods.

In case you're interested, I smoothed out the motion of some servos using constant acceleration/deceleration equations. Here's my really poor quality video showing the smoothed motion.
th-cam.com/video/yoy7H21KJS0/w-d-xo.html
Thanks for showing us these servos. I'm tempted to get a couple of those large servos myself.
Awesome video! Lot of servos I never saw before, very well made. Where did you get the servo at 4:15 tho? I couldn't find it anywhere
greetings, you have done very well especially on the super300, by what you shown, it does not
seem possible to add a "wheel" on it, please correct me because of my ignorance;
again, great work, thanks for sharing!!!
Yes. The great problem with this servo is that it does not have bearings. Thus it is better not to connect the "wheel" directly to the motor. Probably it is possible to mount the bearings instead of bushings. I will try to check this. Thank you for your comment!
@@Skyentific sure thing, there are 2 "observations"..00) the back side if the shaft is "slanted", and 01) even if one removes the casing, there is the pcb board...so to build such a free "wheel"...one may have to build a
case external to the motor's housing...
please ignore my ignorance;
But what about the precision of these servos? Especially the super 300? Do the have a good angular precision?
Great question! I still need to test it. I will do this test and will make a short video with the result.
Hello! Can you explain what do you use as accumulator for super300?
Can I power the 2nd servo you talked about with my 3s lipo
Hey there I have question. Can a 14 Kg cm can able to rotate a 14Kg object like panel? because Im planning to put in a solar tracker
Hello. Which servo motor do you recommend for automatically rotating knobs of used electric stove?
your presentation on these servos are with interesting detail, thank you, i also have noticed you used a pot to control
that super500 servo, hence my question, how would you connect this super500 servo to a arduino with or without a controller/driver.shield , thank you for your time and your response;
I wonder if the giant servo has a magnetic encoder instead of a potentiometer, because the torque of the motor would just snap off any physical end points?
Having a non-contact encoder and setting the end stops in software would eliminate risk of damage :)
You are right! This is exactly the case! It does have a magnetic encoder (AS5600 from ams company).
Are you going to replace the brushless actuators for servos or they are just for testing?
As always, thanks for the great videos!
I'm looking forward to see the robotic arm finished, it seems to progress very well!
cud u pls give me the link to buy those servos, especially the smaller ones
I would suggest that u should definitely try out dynamixel pro plus servo motors this are perfect for your arm and definitely fulfilling your requirements..........
They're great but they're staggeringly expensive. On some of his other videos he's been building custom robotic servos with brushless motors which achieve much the same thing as dynamixels.
What is the name of the smallest servo motor? I need it for my project please
Sir 3.5 kg servo motor is it works on DC current sir plzz reply🙏🙏🙏🙏
Great video! I’m not sure which motors move 180° I need a servo that moves 180 and somewhat fast. And wondering how I can make it move with a push of a button, and then return with another push of the button... I’m guessing I’d need an arduino to control it or something like that? If you could help me out that would be awesome! You seem to know your servos 😁
You might be better off with a geared motor and two limit switches if you only need two positions.
To get more movement you can open the servo and remove the end stops from the output gear.
What about the operating voltage of Super 300 servo motor, whether it's an AC supply or DC supply i.e (12-24)AC or DC?
Can i use futaba nes517 in 1/10 scale rc?
can i connect the big one (300) with an arduino to control it?
Which servo motor is best
Hey what is the device which you are using to test servo motor??
smallest servo motor how yo buy please given a link ???
Hello
Is there greater than 3kg.m , i want bigest servomotor for use it in industry ?
Where did you get your super 300 servo?
where do you buy them?
What are you using to control the servos? Arduino? I'm quite new to this stuff and I'm quite interested.
It's just a standalone servo controller used for testing the servos, but an arduino would work just as well.
8:00 where to buy the purchase link
Hi. What is the name of the unit that have potentialmeter you rotate that make the motor rotate backward and forward? Thanks
This is called servo tester. It is very cheap, and you can find it almost everywhere.
I would like to buy these for sound design. Where did you find the thing that plugs in and controls these?
If I am not mistaken, it called “servo tester”. You can find them on amazon, or hobbyking website.
Skyentific Awesome I found!! But how can I find the wire that connects to the servo? And also a power supply... sorry I am a total beginner because I just wanna record the audio hehe.
You didn’t say the size of each servo. This is information that is hard to find. I need to know every single size servo made.
someone can tell me the diffences between Mg996r and nema 17? except of the torque..
What does it mean to write 10kg/cm on a DC motor?Will it be measured from the center of the shaft or above it
This is torque. It is 10kg.cm. It means that at 1cm away from axis it can lift 10kg. At 2cm away from axis it can lift 5kg. At 10cm away from axis it can lift only 1kg.
Hey, I was wondering if I could ask you a question?
Yes, of course, you can! Even you should :)
Which one is the quietest?
I am trying to purchase VSD-11AYMB SERVO but I am having a hard time navigating their website. Where did you get yours?
You can share servos links? I need 300kg servo web site
'
i use very good HiTec / Traxxas servos are good on my any R/C tamiyas / traxxases...
few futabas servos
Which servo can fit in my ironman suit?
my apology for troubling you ,
since i have already obtained the dimensions of your super300 from that hobby website;
any chance you can tell me the size of the screws that will go through the holes on that
super300( the 3kg/m torque)??? the information is for building a 3d structure for this super300
motor, so you can see whether one can build a "dummy" shaft on the opposite side of the
REAL SHAFT;
at your convenience let me know
The output shaft is 8mm in diameter. The holes on the servo body is well suited for the M5 screws.
@@Skyentific thanks !!!
Hello bro ..
Using RC how can I make servo go from 0 to 30 degree and return back to 0 ... only by one click on the RC
connect an arduino to RC receiver, then arduino does the job (after programming it)
Exactly! I would also choose this solution.
@@rodstartube but sorry bro I want it on RC not aurdino
@@user-rl7vb6vw3bto say in simple words... in your hands you will still have your RC, however, your servo connected to an arduino, and the arduino will be connected to your RC receiver, to obey your RC transmitter commanded by your fingers, and your fingers commanded by.... Allah ??
Some advice on the terminology: it's not kilogram PER centimeter (kg/cm), it's kilogram centimeters (kg*cm). The first one has a totally different meaning, maybe you'd use it to specify the weight of some metal profiles per length.
I'd like it more if people would use the Newton meter (Nm) more, because that's the scientifically correct unit for measuring torque (ounce inch in the US). But maybe it's easier to understand for people with no technical background that way.
Thank you for advice. English is not my native language. I do know the difference between kg/m and kg.m. I have PhD in physics. But when I try to talk fast, I do a lot of mistakes.
@@Skyentific english isn't my native language either. Don't worry, I just wanted to clarify it for other viewers because many get confused by this.
Лайк, подписка )
50kg per cm? What does that mean in real life example
Sir i want servo motors
6:06 That's a big glockk
nice video. but no talk about precision or accuracy
Damn that servo is as big as your head :D
:))))
8:07 that is not a servo, it's a car engine :))
Awesome ...make a sentry gun with these servo*
Also put an artificial intelligence on it. And make it go crazy :)))
