The RK series incorporates new functions and state-of-the-art technologies to achieve the ultimate performance of a stepper motor. The RK Series offers both the high resolution and smooth motion of a microstepping system with improved response characteristics found in a high performance stepping motor solution. The RK series "Smooth Drive" function achieves low vibration without the need for a higher cost pulse generator.
  • Lowest vibration motor performance
  • Smooth Drive function
  • Geared options
  • IP65
