My home built motor controller for use on a go kart or other small vehicle. Wanna help support The WorkBench? / theworkbench www.paypal.me/TheWorkBenchYT
I'm able to use either a pot or a hall sensor with my controller because they both use 5V and output a voltage between 0 and 5V. It depends on how your motor controller works. If it relies on resistance between two points and not a voltage, then the hall might not work.
I built the controller from parts I had around. I'll be doing a video sometime soon on how it's built and how it works since I have so many people interested in it.
The pot you're using is a logarithmic(audio) taper like the volume control on a stereo. What you want to use is a linear (taper) potentiometer. That will give you a reasonably 'linear' increase in speed.
@patchcords It's not actually a pot, it has what's called a hall sensor in there that uses magnetism to change the voltage output. When you rotate the grip, the magnet moves over the sensor.
It looks like you've got it set up for speed control, which, at first thought, would be the way you want to do control for a vehicle (like a go-kart). In actuality, a car uses torque-control instead of speed control. If you use PWM to control motor current instead of speed (voltage), you can get much better response when you're driving the vehicle.
I built the controller from scratch using a schematic I reverse engineered from a cheap Chinese kids scooter controller. Then I just made the output capable of handling a larger load.
Awesome info! im trying to power a tangential Fan, with TAL h60/385/24V. i was wondering if maybe something similiar to what you're doing might work for me i love how you can control the speed! i woould love to get some feedback thanks!!
I have a pwm, but when i want to connect my accelerator (is like your.. type motocycle) doesnt work, but when i connect my potentiometer work perfectly..my accelerator type motocycle do the hall efect.. please help me
Which pwm do you have? What is the voltage range and the amperage. Also what is the voltage, mean ( or rms) amperage and the peak amperage of the motor.
Good work. What kind of amperage the controller can handle? Very much looking forward to your controller build video and/or more info on the circuit. Thanks
I'm going to make a video about how it works and how it's built soon! I've had a lot of interest in this and I didn't think I would so I didn't bother to make the video very detailed.
@@Fans_CristianoRonaldo7 muhammed it really is not worth making it yourself. You can buy a 60amp (peak) , 36 volt one for about £12 on ebay, brand new. If you purchased the components alone, for one of similar spec , it would cost you more than that. Then you have the hassle of building it, and the inherent risk of damaging individual components. So truly, it aint woth the bother of biilding it youself.
TheQwertyCody I don't know who makes this motor. I bought it used and the seller told me it was supposed to be a 500W motor, but other than that I don't really know much else about it, sorry.
@@aaahandy It looks to me like a Chinese Pihsiang 24volt 500watt bldc motor which are commonly used in mobility scooters. If you cannot find one for sale on the internet, which doubt, as they are so commonly available on ebay, let me know. I am almost certain I have a few spares in my workshop. I would not charge you for the motor but you would have to either collect it from my home in west london, or, alternatively, send me the cost of the postage to you. This could be a few pounds as these motors are quite heavy.
anshuman mishra I built the controller completely from scratch by copying a simple motor controller. I'll be doing a video on how I built this, hopefully soon.
Look on ebay. But first decide which motor you need. You state that you need that motor then you contradict yourself by saying you need something totally different , i.e. a 24 volt motor. You can pick up a 24v for about £30 secondhand. But a 36v could cost 3 times that. I suggest you look at your old motor, get the make, modrl, serial number, voltage, wattage and amperage, allof which are on the motor body. Then trawl emay for one.

I haven't actually measured that so I'm not sure, but I think the motor is rated up to 3000 something RPM at 36V
If you're talking about the dark grey thing, with all the cables coming off it, that's the motor controller.

haha "Make sure nothings shorting over here.." I say that to myself all the time when working on my own projects
Nice demo and video.
It is PWM. It's not varying the voltage. It's switching the output MOSFETs on and off.
I built the controller from scratch using a schematic I reverse engineered from a cheap Chinese kids scooter controller. Then I just made the output capable of handling a larger load.
How
The box is the motor controller. It contains the electronics that drive the motor.
@AllAmericanFiveRadio Thanks!
Is there a chance to get your schematic for the controller ?
Thanks,
Malik

What is the black box there? i have a throttle just like that.
What is the resistance of the original pot in the hand control ?
what type of motor controller is that ... operating range of the motor controller is ?
How does this qualify as a home built motor controller when the controller you have is a purchased sealed device?
what type of POT did you use
Donde puedo comprar ese kit?
I was confused when I went back and looked at the video, but then I remembered. it's a small metal shelf rack.
I think the pot was a logarithmic one.
Where can I get one of those motor controllers? What is the name/brand of it?
tienes mas videos amigo con detalles del producto.
Where can i get that black motor controler, whats the name black controller?? Please
It is a 36volt bldc motor control module. You an get then om ebay secondhand, for about £100
I have a pwm, but when i want to connect my accelerator (is like your.. type motocycle) doesnt work, but when i connect my potentiometer work perfectly..my accelerator type motocycle do the hall efect.. please help me
Obviously either you have the wrong pwm or you have wired it incorrectly.
Which pwm do you have? What is the voltage range and the amperage. Also what is the voltage, mean ( or rms) amperage and the peak amperage of the motor.
what's the upper right thing at 0:05?
Good work. What kind of amperage the controller can handle? Very much looking forward to your controller build video and/or more info on the circuit. Thanks
It needs to be able to carry 50 amps peak
what's the brand/model of the actual controller? thanks
Ola onde poso compar esta controladora!
Onde posso comprar um motor igual a este?
I know you made this video 9 years ago just wanted to know if it would be possible to make this run on an Rc style wireless controller
how many amps can it handel?
I need a muy kit 24 vlt
were can i bay thies
what is the diameter of motor
Does it matter if the batteries are lipo like 3 12v 3000kv?what woul happens?:)
James Doornewerd
James Doornewerd it would die fast but it would still work
Your pot could be a log pot wired backwards.
will you bw so kind in order to put the names of the components?
thanks
How to make it remote control.
I'm going to make a video about how it works and how it's built soon! I've had a lot of interest in this and I didn't think I would so I didn't bother to make the video very detailed.
awesome project but they cost next to nothing online. thanks for sharing. did you make an ebike?
This video is old they were nowhere near cheap back then
Did you build that motor controller yourself? It doesn't look homemade...
I used a case from an old amplifier and made the PCB, and end plates. So other than the aluminum casing, the rest is homemade.
The Workbench
Can you introduce or give the wiring diagram of PMW

Please can you provide circuit diagram
hello what are you using to control the motor? What is the box you switch on and off?
The control module
How much ????
We expect circuit for making controller not to make connectins
Sweet
It should be a 22k potmeter.
Where did you get the accelerator?
Off an old electric scooter. They are pretty cheap and easy to find on ebay by searching for "electric scooter bike grip".
@kore464 Thank you for the info :-)
Can you send me schematics and list of components you use??
You will save me
i mean the one u connected with the wires 0:06 (where your finger was pointing and above the wires)
You mean 0:06
10 years ago, Wow😶
Where did you buy all of these pieces

Reverse the white and black
what is the battery capacity?
These were just common 12V, 7Ah batteries.
from where i can get these components ?? can you provide me any link or circuit or any other thing by which i can design this .
