I have a DC motor with specs:
3HP
90VDC
RPM 4000
Duty Continuous
Rotation CW
INS. F
That's all that's on the label. It's in a treadmill, the motor control board has burnt out http://forum.allaboutcircuits.com/showthread.php?t=61884 and I'm looking for a simple motor control to replace it with. I'd like to just hook it up and mount a rheostat, the treadmill is very high quality and I would like to continue using it. When I search for 90V DC motor controls on Ebay and the like, I can only find controllers that handle up to 1.5 HP at 120V. Is it o.k. to use a controller that is rated for half the HP as what the motor is rated at? Can anyone recommend a controller to use with this motor? The diameter of the motor shaft that the belt is connected to is 1 5/8" and it is connected to a 4 inch pulley on the running belt. The max speed of the treadmill is 12 mph. http://s1236.photobucket.com/albums/ff448/systemcore7/
