Performance evaluation of synchronous reluctance motors with and without permanent magnets

摘要

Nowadays, a growing interest in the efficiency andthe cost of electrical machines has been noticed. Therefore,Synchronous Reluctance Motors (SynRMs) have become moreattractive, thanks to their higher efficiency and neverthelessacceptable cost compared to induction machines. The rotordesign of SynRMs with or without permanent magnets (PMs) hasa huge effect on the motor efficiency, torque density and powerfactor. This paper introduces an evaluation for the performanceof SynRMs with and without PMs in terms of efficiency, torqueand power factor maps. Three different rotor designs for thesame machine have been compared. For one machine, theexperimental measurements have been obtained and thevalidation of the simulation results have been confirmed
