Hey I'm trying to figure out how to make a Speed Controller for a DC motor.
It is a 1200 Watt, 48v motor capable of 27 max continuous amps. I'm powering the motor with (4) 12v 12ah SLA batteries.
All of the speed controllers I've seen marketed for my setup seem to be pretty expensive 90+ dollars.
So is it possible to just use a 555 timer to switch on and off a mosfet driving the motor?

- What would be the ideal frequency? I heard that some frequencies make audible tones??
- How exactly can I drive the mosfet? Is the 5v output enough to drive a power mosfet? If not how can I amplify it?
