In flywheel system, rotor is supported by mechanical bearing. In the cases that the weight of the rotor is heavy and the rotational speed is high, mechanical loss is large. Superconducting magnetic bearing (SMB) is introduced to support with contact-less and control-less. The rotor is supported by the pinning effect in SMB. Pinning force depends on the specification of the HTS. In this paper, the...
The magnetic bearing using the high temperature bulk superconductor (HTS) has been developed. In this system, the ring shaped permanent magnet is installed in the rotor. It has two poles. This configuration realizes increment of the linkage flux of the surface of the HTS on the stator. Pinning force of the HTS is used to support the rotor weight and keep the rotor stability. Pinning force depends...
