ABSTRACT:
A momentum wheel energy storage system employs a semi-passive magnetic bearing. The system provides advantages over chemical electrical storage batteries including enhanced storage life. The use of passive permanent magnetic bearings for radial control in combination with active axial control results in a flywheel energy storage system which eliminates several components of conventional flywheel energy storage systems. The energy storage system can be employed in orbiting spacecraft to provide the dual functions of storage of energy from a spacecraft solar collector and control of spacecraft attitude and attitude stabilization.
