1. Introduction
3M660 is a constant torque microstepping driver, voltage range from 24-58VDC, it’s suitable for various 3-phase NEMA23 & NEMA34 hybrid stepper motor.  With the build-in constant current chopping circuit similar to servo driver, the motor run stable without vibration and noise in low speed.  The torque in high speed is far better than traditional 3-phase and 5-phase stepper motor because of the high voltage.  The precision can be high to 12800 steps/rev.
