Please help electronically challenged person to pick a suitable speed control. :) for this DC motor:
I am not very familiar with DC motor/Speed Controller stuff so any educational information/links is appreciated.
Thanks
hello!I'm a student majoring in electronic.I think your circuit need a PWM singal generator and a driving amplifier.With ordinary IC like KA7500b ,we can get a PWM signal,and it's output is strong enough to drive MOSFET or IGBT. Is 40A too big for this 2 HP motor?According to this value,we can select a proper transistor or use some parallel MOSFETs.
