Structure Comparison and Performance Analysis of Multi-Layer Flux-Barrier Hybrid-Pole Permanent-Magnet Synchronous Machine

As its numerous excellent performances., multi-layer flux-barrier hybrid-pole permanent magnet synchronous machine (MLFB-HP-PMSM) is applied in a lot of fields., for example electric vehicles., aerospace., home appliances and so on. In this paper., the comparison of structure and performances of MLFB-HP-PMSM are investigated. First of all., two structures of different PM arrangements of two layers hybrid poles are established and recommended. Then., on the premise of ensuring consistent use of permanent magnets of two structures., the electromagnetic performances of two motor structures are compared. After that., the better performing motor structures have been used for further research., involving the influence of motor structural parameters (flux-barrier angles) on electromagnetic torque.
