Ironless Arc Motor (ARC Series)

  • Ironless Motor
  • High force output
  • Peak force up to 5366N, Continuous force up to 1073N
  • Ideal for high precision/smooth motion
  • Integrated with hall sensor

Optimally designed for low profile high precise arc applications.

PBA ARC Series is specifically designed for angular motion with constrained Arc motion, 360 degrees or multi-turn rotation motion. Powered by high-torque low-profile Ironless arc motors, the PBA ARC Series Motor can be arranged in a large centre hole of up to 1504 mm wide. Coupled with large-diameter circular encoder scale and arc or angular bearings PBA ACR Series motor can achieve exceptionally smooth, precise motion with higher accuracy & repeatability.
