I’m designing a pitching machine for a friend. I have two 24v 22.5A 400W(.5hp) DC motors (with a diode installed across the leads), and 2SK2529 MOSFETs rated for 60V/50A and high-speed switching, and a 24v 12Ah battery.
I’ve driven DC motors using arduino PWM and transistors before, but they were no where near as high a current load as these.
I’ve seen some DC speed controllers online and they seem far more complicated than the simple set-up I’m looking to use, although they probably include an H-bridge for direction control. But these big robust speed controllers make me think using a MOSFET and PWM are too simple.
So can I use these MOSFETs to drive these motors with PWM from an arduino? Or do I need to look at a more robust speed controller?
