Hello all,
Required please a circuit for,
24volt dc 100amp reversing motor speed controller with dynamic breaking
slow
speed high torque required for the 750W 24v motor.
This is for a miniature seven and a quarter inch gage railway engine of
the
type used to pull sit upon carriages that will carry several adults or
lots
of kids. Power source will be 2 12volt leisure batteries about 65ah.
Use PWM on a high power MOSFET to control the motor speed forward.
Do PWM to a resistive load for dynamic breaking.
Use a (big fat) DPDT toggle switch for reversing the motor.

Anyway to get the braking to put some power back in to the batteries?
George.
