Flywheel Energy Storage System Using SMB and PMB

A new energy storage flywheel system using a superconducting magnetic bearing (SMB) and a permanent magnet bearing (PMB) is proposed. The superconducting magnetic bearing (SMB) suppresses the vibrations of the flywheel rotor. The permanent magnet bearing (PMB) passively controls the rotor position....

Description
Summary:A new energy storage flywheel system using a superconducting magnetic bearing (SMB) and a permanent magnet bearing (PMB) is proposed. The superconducting magnetic bearing (SMB) suppresses the vibrations of the flywheel rotor. The permanent magnet bearing (PMB) passively controls the rotor position. The energy storage flywheel system is characterized by using the two different type magnetic bearings of permanent magnet bearing (PMB) and superconducting magnetic bearing (SMB). Dynamics of the new energy storage flywheel system are discussed in this paper.
