Flywheel Energy Storage System with Homopolar Electrodynamic Magnetic Bearing*
.Abstract – The goal of this research was to evaluate the potential of homopolar electrodynamic magnetic bearings for flywheel energy storage systems (FESSs). The primary target was a FESS for Low Earth Orbit (LEO) satellites, however, the design can also be easily adapted for Earth-based applications. The main advantages of Homopolar Electrodynamic Bearings compared to more conventional Active...
متن کامل2 MW 130 kWh Flywheel Energy Storage System
The Center for Electromechanics has developed and is currently testing a 2 MW, 130 kWh (480 MJ) flywheel energy storage system (FESS) designed as a load leveling energy management device. The flywheel energy storage system consists of the energy storage flywheel, a high speed induction motor/generator, and a bidirectional power converter. The FESS is a key element of the Advanced Locomotive Pro...
متن کاملCharacteristics of superconducting magnetic bearings for 50kWh-class flywheel system
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 le...
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...
متن کاملEddy currents in a passive magnetic axial thrust bearing for a flywheel energy storage system
Two types of passive magnetic lift bearings were evaluated in terms of thrust force and eddy current losses. The first type of bearings were based on two sets of segmented Halbach arrays mounted in repulsive mode, and the second type was based on ring-magnets. The eddy-currents studied arose in the bearing due to manufacturing variations of magnetic remanence, and due to non-radial magnetizatio...
