What's the difference between that and modern cordless drill motor?
Size and weight? Obviously cordless drill motors are smaller/lighter. Is that due to higher quality and miniaturization? Or do scooter motors have to be big/heavy?
Power and efficiency?
I'm wondering why a scooter motor has a DC motor controller with a big aluminum heatsink. What sort of motor controller does a modern cordless drill include? Why doesn't it require the same?
Apparently cordless drill motors are powerful, at least the way they are geared. Scooter motors use a belt/chain.
As far as I can tell, given the revolutions per minute, the speed using either motor would be about the same (the scooter motor as assembled and the cordless drill motor driving a wheel directly from the chuck).
What about back pressure on the drill motor? Usually that doesn't happen like with a scooter motor.
I don't necessarily need all that answered, any comments or insights are welcome.
