Motor controlers?

I have a 24 volt motor from an old mobility scooter and I want to control it with my arduino but I have no idea what motor controller to use. I presume that I will need to use PWM to control it but what hardware to use I have no idea. Any help I would really appreciate.

Get the drive from the old scooter if you can !
Agree, but if u cant get it anymore, what you will need is an high power Mosfet H-bridge. PWM goes into the mosfet gates, there's plenty of information and schematics on that. You will probably need to use arduino PID library too in order to get a smooth control.

+1 Don't reinvent the wheel, just use the system that was already in place to control it.
