5-Phase Stepper Motors


RKII Series 5-Phase Stepper Motors (AC Input)

5-Phase Stepper Motors - RKII Series

The RKII Series Stepper Motors are designed to provide high performance and energy savings combined with a high performance, low cost AC Input driver. To achieve constant maximum torque output with lower heat generation and save energy, the motor losses have been substantially reduced allowing them to be operated for longer hours at high speed which is not possible with conventional stepper motors.  For use with RKII Series AC Input Drivers.

  • High-Efficiency
  • 0.72° (500 pulse/rev)
  • Wide Range of Gear Types for Inertia Matching & Higher Torque
  • New Pentagon Winding
  • Encoder and Electromagnetic Brake Types
  • 5-Phase RKII Series Drivers Required*


PKP Series 5-Phase Stepper Motors (DC Input)

5-Phase Stepper Motors - PKP Series

The high-torque PK/PKP series stepper motor offers balanced performance enhanced by high torque, low vibration and low noise.
