Closed-loop performance of a six degree-of-freedom precision magnetic actuator

  title={Closed-loop performance of a six degree-of-freedom precision magnetic actuator},
  author={Zhaohui Ren and L. S. Stephens},
  journal={IEEE/ASME Transactions on Mechatronics},
The slotless permanent-magnet self-bearing motor (SBM) technology is used to fully provide radial bearing and motoring functionality simultaneously in a six degree-of-freedom magnetic actuator for potential precision pointing and tracking applications in space such as intersatellite laser communications. This novel precision magnetic actuator incorporates two SBMs to produce both radial bearing forces and motoring torque, and one active magnetic bearing to provide axial support, and thus allows… CONTINUE READING
