چکیده :

Consequent-pole flux reversal permanent magnet machine (CP FRPMM), featuring low consumption of rareearth materials, high torque density, and efficiency, has captured increased attention over recent years. However, prior evaluations of CP FRPMMs have largely been confined to intra-family comparisons, leaving their potential relative to other CP machine variants underexplored. To address this gap, this paper compares the electromagnetic performance of two CP FRPMMs with their consequent-pole Vernier and flux switching counterparts. For a fair analogy, all topologies are designed under the same geometrical dimensions, number of stator slots and rotor teeth, winding configurations, input current density, and rotational speed. In addition, the torque characteristics of all models are optimized globally via multi-objective genetic algorithm (MOGA). The performances of all machines are assessed under no-load and on-load conditions using finite element method (FEM). It is revealed that the flux reversal machine with quasi-halbach arrays of PMs outperforms other designs in terms of torque density, efficiency, overload capacity, power factor, and field weakening capability.
