Hi everybody. I currently have an induction motor bench grinder/buffer that is a single speed (3450 RPM). I also have a voltage regulator laying around.
Does anyone know if using the voltage regulator to lower the speed would harm the motor?
I am aware of the possibility of harming the motor if the RPM goes to low because this would lower the speed of the cooling fan to an unacceptable speed. However, I don't plan to go really slow (maybe 1500 RPM).
It's an 8" Grinder/Buffer 120 Volt, 4.8Amps, 60Hz, 3/4 HP
Thanks in advance.
