Induced Eddy Currents by BLDC Machine Stator Reluctance Variation

摘要

Stator slot openings are causing the magnetic flux density changes in permanent magnets (PM) of outer rotor HI.IK* machine. The results of these changes are induced eddy currents and with them power losses in permanent niii'Micts. The magnetic flux density distribution and peiiel ration into the rotor are described.
