Please help me to choose a variable speed control for a DC motor I just got an electric DC motor that came from Graco GM5000 air sprayer. I want to use it on my belt grinder to make it variable speed. What kind of speed control I would need for this motor.
Here is the DC motor specs:2 HP 130 Volt AMPS 18.0 / Max AMP 40.0 Type DF Torque 38 F.F. 1.38 Serv. Factor 1.0 Encl. TEFC
Any suggestion appreciated. Thanks
