Abstract

Introduced the structure of a magnetic bearing reaction wheel for stabilization of spacecraft attitude, its rotation speed is from -5000rpm to 5000rpm (rating angular momentum is 20Nms). The main scope of this paper is to calculate and analyze the performance and parameters of the hybrid thrust magnetic bearing with permanent magnet bias for the magnetic bearing momentum wheel. Its magnetic force, current stiffness, and position stiffness are derived by using the equivalent magnetic circuit and their non-linearity are shown by the curves of force-current-position characteristic. The ranges of bearing capacity is obtained.
