Quality PWM control for 45V/80A

[neutrino 36]

Hello All!
I need a project or schematic for quality PWM control of DC-voltage 45V and max current 80A.
With this control I want to drive DC-motor with 42V and current of 50A.
Thank you !

Couple of questions to get us going:
Is 50 amps the stall current or the running current?
Bi-directional?
What is it for?

Here is an easy way to do PWM for a DC motor. By matching your mosfets to the needs of the motor, it will drive just about any DC motor. **broken link removed**

Hello!
PWM controller need for controlled DC-motor (engine) for DC- voltage 42V/50A, not the DC voltage of 35V.
thank you
