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

Steppers actually sound like an interesting possibility for RSG motors,
if they'll spin fast enough. Anybody tried it?
