It is available with two cable orientation, in a 42 mm or 60 mm mounting face and in AC input only driver control. Optional electromagnetic brake type is also available.

The AlphaStep AR Series stepper motors offer high efficiency, low vibration, and continuous operation with the security of closed loop performance without hunting or gain tuning. Available with a built-in controller or pulse input driver, the system substantially reduces heat generation from the stepper motor through the use of high-efficiency technology. The RKII series are 5-phase AC input stepper motors designed to provide high performance and energy savings.
