did anyone used this motor succesfully to get any decent speed?
if so what drive did you use and at what voltage..Thanks

Valmet58,

I believe 75 to 80 volts would be about average.

The torque falls off really fast on that motor.

What is the TPI of your leadscrew?

What kind of Driver and power supply do you have?

Im running 4 of them, off a keling 20A 75 or 78V (not sure) power supply. Running them on a rack and pinion router were 1 turn of the motor gets me about 3 inches so my rapids are retarded fast - 2000ipm, I have to run Quantum though because starting and stopping an 8ft travel at 2000ipm nearly knocks my machine over from the momentum :P
