Re: [TCML] wheelchair motor



It could be done with steppers, but steppers don't make a lot of sense (these days as far as costs). The wheelchair is obviously 12Vdc or maybe even 24Vdc. The motor is obviously a gear motor. Likely a brushless DC motor but maybe even a brush DC motor. The torque is in the gearbox. The motor itself is probably rather low on torque and maybe 1500 to 3000 rpm (likely the lower range). Why pay the expense of a stepper when a brush or brushless will do the job?

Easy to tell the difference. A standard DC motors has 2 wires attached to it. A typical brushless uses 3 hall effect sensors plus power and ground and the 3 motor leads. Likely 8 or 9 wires coming from the motor if brushless.

Take care,
Bart
