Simulative analyses of the rotor for magnetically suspended flywheel with vernier gimballing capacity

Magnetically suspended flywheels provide a number of attractive advantages over ball bearing wheels. As an important executive component of satellite attitude control system, the improvement of flywheel system is spurred by high performance satellite attitude control system. The general situation of the flywheel with vernier gimballing capacity is introduced. To reduce power consumption and augment the outputting torque of the existing magnetically suspended flywheel when the rotor is tilting, a innovative 5DOFs magnetically suspended flywheel with vernier gimballing capacity is proposed also its composition and working principle are introduced briefly. As the most important part of the flywheel, the rotor is analyzed by finite element analysis software ANSYS-Workbench, including mode, harmonic vibration and random vibration simulative analyses. The analytic results indicate that structural design of the flywheel is reasonable. The analytical method takes an important part in designing the flywheel which is not only factualistic but also effective.
