Design of a Hybrid Permanent Magnetic Flux Switching Machine with compound rotor configuration

Abstract

Hybrid Permanent Magnet Flux Switching Machine (HPMFSM) is a machine that uses two permanent magnets which are Ferrite Permanent Magnet (FPM) and Rare Earth Permanent Magnet (REPM). The REPM had being implemented widely in HEV nowadays. So, HPMFSM is created in order to reduce the volume of REPM itself. Three designs had created which are PM, PMH and SMH design. PM only consist of REPM, meanwhile PMH and SMH consist REPM and FPM. The difference of the PMH and SMH is the arrangement of permanent magnet. The machine can generate higher performance by combining FPM and REPM. The HPMFSM load analysis is conducted in order to verify the 7pole/6slot/7pole HPMFSM machine performances. Through the analysis, the performances of the machine are able to identify. The PMH design can compete with the PM design which gives higher torque density.
