Thank you. I know its late but I thought these motors were seized up and I was going to scrap them. I removed the brake and tested them. They will now have a new life as a boat motor.

[@purplepenguinproductions2552]

Man I looked all over KZbin and this is the best video I found for this

[@neuromonkey]

Thanks, man! This was really useful for me. A friend just gave me power chair hardware, and I didn't realize that there was a magnetic brake.

[@HsingSun]

Thank you for your video. It is the 1st one that I watch how to rewire the "power chair motor to robotics."

[@Harrzack]

Thanks! Would you believe I found a whole chair, discarded by the Demster Dumper in our complex! I got the motors/gearbox/wheel AND the joystick control as well as the front wheels. Didn't keep the batteries as they were swelling along their sides. THANKS for the break explanation - as well as that they seem to go on 12v

[@automationgroup2652]

Just what I needed thanks!

[@mot6021]

It is a worm gear, to make it go faster modify the low speed shaftr to fit in place of the high speed shaft and gear so the worm gear drives the wheel directly without reduction

[@GizmoGuy620]

I don't think by using 12V you would damage these motors. Since I will be using them for a relatively slow robotic car, the 12v is good. The motor is rated for 24v so basically it would use less current at that voltage. An example would be: if I need 100 watts of power @ 24v it would draw 4.166 amps. That same 100 watts of work @ 12v would draw 8.33A from the batteries. That's why I will use 2 Gel cels in parallel rated @ 8AH for a total of 16AH @ 12v

[@RetreatfarmFarmvilleVirginia]

I Advertise on Craigslist for broken or unwanted power chairs and get about three average per year. I just picked one up yesterday with HMC Motors in fair running condition. I build handicap gardening carts for people to do rowcrop gardening.

[@theronwinsby]

Can you contact me please. I want to make a garden cart like you do.!

[@TheMotorgoat1]

@fcord23.....I was just reading through the comments and saw that you're running them at 12v (parallel) instead of the 24v (in series) like they were designed/built to be run at. I just wanted to say that from what I know about electronics and especially motors, if you must, it's better to run them at a little higher voltage then they're rated at opposed to a lower voltage. When you do the latter, it draws more amps (double the amount in this case) then what it was designed for and depending on how much extra amps/how hard your working them, will result in straining, overheating and or even frying out the internals. All of which will definitely shorten the motors lifespan. Just figured I'd mention it and either way, good with everything..peace

[@GizmoGuy620]

Hello Motogoat1 and thanks for your input. I am sorry I do fail to mention the motors would not be run directly from a battery, but thru a motor driver (such as a Sabertooth 2X12) or some other PWM power circuit. This will help to reduce any large current drain and or over heating.

[@lucasgreer5796]

Good video but just for reference that brake is called a "active low" brake basically if you want to keep the brake for some reason apply voltage to the 2 white wires and it will disengage it's the same type you see on alot of industrial equipment

[@GizmoGuy620]

Removal of brake was just to save on battery power.

[@scannaunderscore1]

this has been handy because ive been trying to test an electric bike hub which will not work without the controller box which i think is blown

[@georgeman948]

Good video, I liked how you explained it.

[@GizmoGuy620]

These are standard power wheel chair motors. The label says "Motion Tech Motors" 24VDC / 3A max (but I think they draw more than that)

[@rcbif101]

Did this for my sumo robot in highschool, but now that I think about it, the brakes would have been better to keep in place. Our robot coasted way too much! Made it too easy to overshoot a turn :(

[@GizmoGuy620]

I think you wouldn't have that problem with these motors, they pretty much "lock up" when there is no power. In other words they would not roll down a hill if no power.

[@dudet9662]

2:18 I live on the edge bro.. I'm not here to make robots lol

[@GizmoGuy620]

The brake is pretty heavy duty, I think it would draw a lot of current just to bypass the brake. This would reduce the the power of your on board batteries. I just eliminate the brake.

[@harounabdelali8800]

Hi ... I have the same two motors and trying to build a robot with embedded PC-screen, so I'm willing on saving the most of the two 12V batteries, if you had meanwhile access to their datasheet I'd like to have it to ... Great video by the way the only info I found on the SRG0131motor.

[@GizmoGuy620]

I would keep the engagement lever just in case you have a problem with your creation and need to have it roll freely to another area...

I wonder how much weight these can handle I'm thinking of put it on a dolly to make an electric dolly to move heavy stuff

[@GizmoGuy620]

You need to clarify "heavy stuff". I do know power chairs move some pretty overweight people around.

[@kenh9508]

@@GizmoGuy620 I agree. Could move 350 pounds with years of service. But 1000 pounds probably won't last long.

Good video. How in the world did you not get gear grease on that white carpet?

[@GizmoGuy620]

I didn't open the gear box side :)

[@chop98]

Newb question here for the 24v wheel chair motors. You're simply turning the motor with a 12v battery. Could you actually put a load on the motor for pulling and just run it off a 12v battery permanently? Would there be any damage to the motor itself? I'm just curious. That would save having two batteries in there or one expensive 24v battery. Thanks for the answer when you get around to it. :)

[@motorsandvoltsandrobots7162]

Can your tell me if all these motors use the same mount for the wheels ?

[@chase-hancock]

Mr. @fcord23 do you have any suggestions as to how to engage the worm gear? I understand the lever dictates that, but whenever it is engaged, the motor arm still won’t spin. I don’t know what I’m doing. Just getting into electronics/robotics. Would cutting the white brake wires as you have here, help with that? Thank you so much!

[@GizmoGuy620]

I believe you must remove the brake as indicated.

[@ppowell1212]

Thanks for the video. I am looking for this motor to drive small piece of scenery/platform on stage. As long as the motor is engaged and it's not getting power, does it act like a break? Effectively preventing the platform from rolling? That's what I want, but if I understand you video correctly, that is what should happen...am I correct? TIA

[@GizmoGuy620]

I wouldn't call it a brake, but it doesn't spin freely either. If you need braking action utilize the brake on the motor, you just need to apply 24VDC to disengage it.

[@ppowell1212]

@@GizmoGuy620 Thanks so much for the reply. So if I got a car battery that was 24 volt, I could get the power for the wheel and it would also act as a brake. I'm not to this area so forgive me for asking such basic questions. But how I would I go about controlling the motor, i.e "Go" "Stop" "Go half speed"...in an ideal world...wirelessly, like a RC plane or car. TIA

[@ppowell1212]

If you can point me to some videos that might help, it would be greatly appreciated.

A power PWM controller (such as a Sabertooth 2 X12) can easily control these type of motors.

[@vamphigherextreme4248]

Do you have any idea how to make these motors faster? I'm trying to increase the speed on a powerchair. It won't take more than 28 volts or so and I thought maybe you would know a way around that. Thanks

[@GizmoGuy620]

Sorry I do not. I believe these motors are rated 24v. With the internal gearing, the speed is what it is. Applying higher voltages will most likely damage the motor.

[@vamphigherextreme4248]

@@GizmoGuy620 I had someone in A Quantum chair blow by me like I was standing still yesterday and his motors were no larger than mine. I've already removed the programed restrictions so there must be some other factor governing the power to the motors. These motors could easily handle twice the voltage. The motors are not the problem. I overvolt dc motors all the time. The ratings mean nothing

Thanks for the video.i did the same thing but the 12v and 7 amp battery(D.C) giving only 15 min power to this motor.what is should to increase the time of a battery? can i connect two 12v battery in parallel to this motors? Waiting for your reply...!!

[@GizmoGuy620]

Yes Satish, that's what I am doing for my robot. I have two 12V/ 8Ah batteries in PARALLEL. That still gives me the 12v, but at much higher current (16Ah). I also have a totally separate one for the electronics.

[@satishnamballa3590]

fcord23 thanks for your reply. What is the duration of the battery?How much time the bot/motors can run with 2 batteries? In another video(Robot car) u connected 3 batteries it means one for electronics and remaining 2 for motors right? In my case m designing power wheelchair where one person can sit move move here and there but problem is how much time does two batteries can support this motors to move continuously? Waiting for you reply.

[@GizmoGuy620]

Battery time depends on many things. I am hoping for at least 2 hours. I also hope to make the robot find a charging station on its own

[@lucasgreer5796]

If I'm not mistaken that's a 24v motor so you need to go in series with your batterys because yes you can run a 24v motor on 12v but your going to consume more amps

[@GizmoGuy620]

I needed the robot to run inside a home. I couldn't have it running at 24v because it would be too fast. A slower speed (at 12v) would actually use less amps (by using a Power PWM control).
