The 3M2060 is one of the few Direct-On-Line Step Motor Drive, available in the industry,
which can be simply power up from the AC power source without the need of a Power Supply.
This makes it cost effective and space efficient.
PSD78AC-3P 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.
The higher voltage input of the PSD78AC-3P make it possible to excite a three phase bi-polar
hybrid step motor, with size from Nema 23 up to Nema 42. 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.
