Characteristics of superconducting magnetic bearings for 50kWh-class flywheel system
نویسندگان
چکیده
We are developing a 50 kWh-class flywheel energy storage system as a national project, using a new axial superconducting magnetic bearing (Ax_SMB) technology. The project has started in FY2005 and will continue to FY2007. The Ax_SMB is composed of Fe core and superconducting coil, which are simply torus-shape. It generates strong restoring force in axial direction. It can realize non-contact levitation of 25t mass of flywheel, combined with active controlled magnetic bearings for radial direction (Ra_AMB). Ax_SMB Superconducting magnet Movable core Fixed core Ra_AMB (Lower side) Ra_AMB (Upper side) Motor/Generator

Magnetically Suspended VSCMGs for Simultaneous Attitude Control and Power Transfer IPAC Service
This paper presents the theory and numerical results of utilizing four gimbaled, magnetically suspended, variable speed flywheels for simultaneous satellite attitude control and power transfer (charge, storage, and delivery). Previous variable speed control moment gyro models and control algorithms assumed that the flywheel bearings were rigid. However, high speed flywheels on spacecraft will b...

H∞ controller for active magnetic bearings (AMBs) with flexible rotor system was designed in this paper. The motion equations of AMBs and flexible rotor system are built based on finite element methods (FEM). Weighting function matrices of H∞ controller for AMBs are studied for both the sensitivity and the complementary sensitivity of H∞ control theory. The simulation shows that the H∞ control ...
متن کاملDevelopment of a Passive Magnetic Bearing System for a Flywheel Energy Storage
Magnetic bearings are an attractive alternative to mechanical bearings in flywheel energy storage systems since they greatly reduce friction and wear. However, new problems are introduced in terms of stabilization; particularly the magnetic bearing must provide enough damping to reduce excessive vibrations. Two novel configurations of passive magnetic bearings are introduced to meet system requ...
