Conventional permanent magnet assisted synchronous reluctance motors (PMaSynRels) are characterized by flux barriers partially filled with rectangular sintered ferrite, resulting in barrier shapes constrained to various rectangular combinations. For PMaSynRels with bonded ferrite, flux barriers could be completed filled, but the inferior magnetic properties of bonded ferrite restrict the performance of these PMaSynRels. Thus in the paper, two PMaSynRels with non-rectangular sintered ferrite are investigated and compared to explore the maximum torque potential. Through parameterization and optimization, the final two PMaSynRels are evaluated on torque, power factor, and efficiency across diverse operating conditions. The results prove that PMaSynRel with fluid-shaped sintered ferrite has lower torque ripple than PMaSynRel with circularshaped sintered ferrite. In terms of power factor and efficiency, the two PMaSynRels do not differ significantly.

Abstract
Conventional permanent magnet assisted synchronous reluctance motors (PMaSynRels) are characterized by flux barriers partially filled with rectangular sintered ferrite, resulting in barrier shapes constrained to various rectangular combinations. For PMaSynRels with bonded ferrite, flux barriers could be completed filled, but the inferior magnetic properties of bonded ferrite restrict the performance of these PMaSynRels. Thus in the paper, two PMaSynRels with non-rectangular sintered ferrite are investigated and compared to explore the maximum torque potential. Through parameterization and optimization, the final two PMaSynRels are evaluated on torque, power factor, and efficiency across diverse operating conditions. The results prove that PMaSynRel with fluid-shaped sintered ferrite has lower torque ripple than PMaSynRel with circularshaped sintered ferrite. In terms of power factor and efficiency, the two PMaSynRels do not differ significantly.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
