3M660 is a bi-polar three phase micro-stepping drive applying pure-sinusoidal current control technique. It had the potential of delivering more torque with smoother stepping motion with a three phase motor. This results in lower vibration and higher performance as compared to the two phase type. It is best suited for applications that desire extreme low speed smooth motion, especially in multi-axes linear and circular interpolated application, or application that is sensitive to vibration, at extreme slow speed.
With precise current control technique and optimization in speed control, this three phase PowerStep drive is well suited for three phase hybrid step motor, producing a performance close to a brushless DC servo operation.
