Hi all,
I was wondering if anybody had a circuit diagram for speed controlling a 12Vdc 10A motor.
Spec:
The motor at 12Vdc has an inrush of 45A for less than a second, then stabilises to 10A at full speed.
I am after a mosfet circuit diagram, which I know will be straight forward for those experienced ones, that will be controlled using a 18F4550 using PWM. I was given a circuit board that was damaged which drove a similiar motor that used IRFZ48N. On the circuit next to the mosfets is an MBR1645. Unfortunately the boad is so badly damaged I cannot make head nor tail of it.
The microcontroller side of things I will handle, it is just a reliable mosfet drive circuit that I need to get going.
Any help will be appreciated.
Many thanks,
Andrew
