Electric Wheelchair Motor Test & Brake Removal by VOG (VegOilGuy)


Hi YouTube, my name’s Geoff and I’m the
Veg Oil Guy. Today I’m going to be looking at electric
wheelchair motors. It’s an unusual thing to look at I know, but these motors are very
versatile. They’ve got bags of power and can be used for all manner of purposes. I’ve
got a project coming up that I’ll share with you soon but for now I just want to test
this motor and remove the electronic brake. As I bought this second hand on eBay, I don’t
want to make any modifications until I’m sure it works as the seller has guaranteed
he’ll take the motor back if it doesn’t work correctly.
This is a 24 volts, brushed unit and you should be able to see there are four wires… but
that doesn’t mean it’s brushless. It’s not a magmotor. Two of these wires are for
the motor but the other two are for an electronic brake. It’s critical this brake is not left
on as the motor is tested as it will damage the motor. Now I don’t want to keep the
emergency brake but for now I need to circumvent it to test the motor – then I’ll remove
it. Doing this is very easy. Just undo the two
main screws on the top. What you can now see is the emergency brake.
It’s basically an electromagnet. With the electromagnet off, the brake is one and vice
versa. Electromagnets use a lot of power and I don’t need the emergency brake, so I’m
getting rid of mine. But for the moment let’s just remove it.
Again it’s just a matter of two screws. Off comes the magnet coil assembly, along
with a couple of metal plates. To power the motor I’m going to be using
an ordinary 12 volt car battery charger. The motor is 24 volts but 12 volts will be fine
for testing. Here I’m inserting a couple of probes into the motors power connector. Here I’d realised there was still a couple more parts of the emergency brake to pull
away. No tools are needed here. Now I apply the power and success, the motor
is turning clockwise. It works. But I want to reverse the motor as well, so
it’s just a matter of changing the polarity… swapping over the positive and negative connections.
With that done we can now see that the motor happily turns anti-clockwise as well. That
means I bought a good motor on eBay. This lever acts a like a clutch. When engaged
the motors spins but the driving spindle doesn’t turn. Useful feature… I think I’ll keep
it. Now I’m safe to permanently remove the emergency
brake as I don’t want it. If you want to keep yours, you’ll need to apply 24 volts
to the black wires to power the electromagnet. Anything less probably won’t do it.
With the power disconnected for safety, it’s simply a matter of cutting these two thin,
grey wires that attach to the electromagnet. There aren’t any bare wares showing, but
I’ll add a little insulation tape just in case.
Now I can reassemble the motor cover without including the electromagnet as it’s not
needed. I’ve reduced the weight of the motor slightly and certainly reduced the amount
of power needed to use the motor. With the cover in place and the power reconnected,
it’s time for another quick test… Yes, that works a treat. Job done.
No doubt things will vary slightly between makes and models, but if you need to remove
the emergency brake from an electric wheelchair motor, hopefully you now know how. If you’ve
got any questions, just drop me a line. And that’s it guys. A very short video,
but one that I hope will be useful to someone. If you enjoyed watching this video, please
like it. If you didn’t like it, then why not let me know why. I’m always eager to
improve my videos. Your comments and questions are always welcomed
as I really love to hear from you so do drop me a message below.
Please do check out my YouTube channel and of course my other videos. I’ve got 40 plus
videos out there now and I’m receiving some fantastic feedback and I’m seeing a real
interest from Subscribers, so thank you all for that, and if you haven’t subscribed
yet, please do. So that’s it for now folks, and thanks very
much for watching.

  1. Useful video. I have a couple of these motors and am hoping to use one of them to power a ball mill, the slow speed and power of the motor should be ideal.

  2. I enjoy your video's do you know a way I can get the 24 volts dc to power it for a left to left very havey stuff  or is the reduction not good enough to handle 600 pwonds     sorry for the bad spelling .

  3. I have a Jazzy 600 power chair and I want to disable the left and right turn ability of the motors. I’m using the electronics to push a heavy cart forward and back. I don’t want to use casters to steer it. Any suggestions would be greatly appreciated.

  4. Extremely helpful. I'm using a pair of similar motors for a project and they weren't working right, but I had no idea there was a brake in them. Removing the brakes first thing in the morning! Thanks for the video.

  5. Thanks very much for posting. If you have data on max RPM and torque, can you please include in your description.

  6. I was on my way Home from the Market and all the sudden the Motor on the right Side Stoped , Do you Think it's the Brake ?
    It look's like it want's to Move

  7. my pride gogo traveller elite has new batteries and it can run for hours but get on a steep grade or hill and it becomes such a load that the circuit breaker shuts down the whole scooter and we have to reach down and reset it, and walk the scooter up the hill. very discouraging. what can i do to solve this. if i can replace the motor to solve this it will be simple i think. any
    help is appreciated…thanks

  8. Hi Jeff, i just got a couple eletric wheelchair motors for a remote controlled robot project… Do i really have to deactivate the breaks on them, Or can i just use the way they are?
    Good videos
    Thanks in advance

  9. Thanks! I have just been given a whole set up and wish to build a simple Locomotive using them! The brakes are off TOMORROW!!
    Lots of Love
    David and Lily.

  10. I want to build an electric motor powered cart to haul several hundred pounds. Would one of these motors work well? I am very new to this so can I just attach a sprocket and chain to attach to motor to the axle? Can I email some questions?

  11. so is it correct to say that varying the voltage beneath 24v affects the travel speed? how low of a voltage does it still function at?
    I'm surprised that a wheelchair motor consumes under 80 watts. I thought these things are supposed to push a 500lb american up hills.

  12. Hi just found your site …..fantastic I would like to power a fishing trolley , I'm an engineer but I wary about electrics , I think I can sort out everything except the principle of switches and converters etc I'm probably blowing hot air can you help me ?

  13. I have a similar motor. When I removed the brake and tested it at 12V, it is only consuming 0.1A of power. That seems minimal for the function it provides so I'm leaning toward keeping it.
    What I don't understand is why are there separate wires in the connector for brakes? They could've merged the motor and brake wires together. Am I missing something? Are brakes to be powered on 12V and motor on 24V?

  14. Great video, but would be greater if you add the voltages, ampereres, watts, horsepower, ohms, etc. Also, make your sideline comments twice bigger to read and leave them on for twice as long. Thank you for the video as i learned a lot from it.

  15. thanks for your upload – is that the maximum speed the rotor spins around ? i was planning somehow to use a mobility motor to power up a kayak …
