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 motors available
  • Resolution - 0.72º ~ 0.0.00288º [16 steps] (Microstep)
  • Single-phase 100-115 or 200-230 VAC or Three-phase 200-230 VAC
  • RoHS Compliant
