portanav Posted May 23, 2020 Report Share Posted May 23, 2020 Hello, I am looking for advice on replacing a capacitor for my 1/3 HP 2.8 Amp induction motor (bench-top grinder). I do not have the original capacitor that came with the motor, and need a replacement. What size capacitor should I purchase. Thanks, Michael.

paulengr Posted May 24, 2020 Report Share Posted May 24, 2020 You can’t just guess. It might be printed on the name plate. If you don’t have the information it takes a lot of experimentation to find out. It is cheaper to just buy another motor. Plus many motors have two capacitors or one with both inside. What you have for information is just the start. Small single phase motors are ridiculously complicated things compared to three phase ones.
