Stator Winding Design and Optimization of an Induction Reaction Sphere for Microsatellite Attitude Control

Reaction sphere is a novel and promising actuator of microsatellite attitude control system. Winding arrangement is an indispensable part in reaction sphere design and can largely influence its speed and torque performances. This paper provides different winding arrangement design schemes for an induction reaction sphere based on its special stator structure. The optimal winding arrangement design scheme is provided with the assistance of FEA method and slot-vector star graph. Finally, the experimental prototype and ground test system are developed to verify the proposed design scheme.
