PERMANENT MAGNET RELUCTANCE MACHINE AND CONTROLLER FOR USING THE SAME WITH A SYSTEM

摘要

A permanent magnet reluctance machine (PMRM) uses electromagnetic interaction and the minimum reluctance principle to generate a developed torque that has wide constant torque to speed characteristics and a higher torque to weight ratio. The PMRM uses an axially laminated rotor with interleaved or alternating layers of permanent magnet and minimum reluctance areas that are separated by flux barriers. In this fashion, the PMRM has the characteristics of a permanent magnet machine and a synchronous reluctance machine.
