Help to choose speed control for a DC Motor
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 |

Check out surplus center in NE... they have a controller that will go to 130
volts... but 18 amps is the big bear and not many controllers I know of will go to 18 amps. BUT.. you will probably never pull a full load -- and if you do, just make sure you are fused correctly so it will blow first Steve "Alex" wrote in message . ..
