摘要
This paper provides a performance comparison between three-phase and five-phase ferrite-based permanent magnet assisted synchronous reluctance motor (PMa-SynRM). Recently, research on PMa-SynRM has got significant attention, especially in vehicular applications. They can meet the performance requirements of electric vehicles with reduced or no use of rare-earth-based permanent magnets (PMs). However, these motors face the challenges of lower torque density, irreversible demagnetization tendency, and intolerance to the augmented stress due to the relatively higher amount of PM. These challenges can be mitigated by employing five-phase winding which can develop higher power density with lower torque pulsation compared to the conventional three-phase motor. This paper compares the electromagnetic performance of a three-phase and five-phase Ferrite magnet based PMa-SynRM. A thorough finite element analysis (FEA) has been presented to validate the superior demagnetization preventing capability, and stress tolerance capability of the five-phase PMa-SynRM over the three-phase PMa-SynRM. Experimental results of the induced voltage for fabricated three-phase and five-phase PMa-SynRMs will be provided to validate the FEA results.
