Abstract
A magnetically suspended energy storage flywheel named as FW15-B with very low power loss, has been developed which employs new kinds of permanent magnet-biased radial and axial magnetic bearings (MB), and a new kind of permanent magnet brushless direct current machine (PMBDCM). Before FW15-B, another flywheel named as FW15-A with normal MB and structures has been fabricated just being used to validate the basic flywheel function of magnetic suspension at high speed and to analysis the power loss sources. The two prototyped flywheels and their main components are given. It is stated out by experiment that FW15-B only needs MB power amplifier power of 3.59W when the flywheel is in statically state, and needs PMBDCM input power of 10W when it runs at speed of 25974r/min, compared with 29.6W and 20W respectively for the FW15-A at the same operating states.
