The aim of the present paper is the evaluation of the performance of PM-assisted synchronous reluctance (PMAREL) motors with bonded magnets. Such magnets allow to fill completely the rotor flux barriers obtaining better performance, in terms of torque density and flux weakening capability, with respect to synchronous reluctance (REL) motors and PMAREL with the common magnet typologies. Several neodymium iron boron bonded magnet typologies have been made in laboratory and proposed as alternatives to the most common ferrite bonded magnets. The rotor geometry has been optimized with the multiple aims of achieving the maximum average torque with the lowest torque ripple and to simplify the PM insertion. The motors performance have been evaluated by means of finite elements analysis considering the rotor with and without the PM effect.

Abstract
The aim of the present paper is the evaluation of the performance of PM-assisted synchronous reluctance (PMAREL) motors with bonded magnets. Such magnets allow to fill completely the rotor flux barriers obtaining better performance, in terms of torque density and flux weakening capability, with respect to synchronous reluctance (REL) motors and PMAREL with the common magnet typologies. Several neodymium iron boron bonded magnet typologies have been made in laboratory and proposed as alternatives to the most common ferrite bonded magnets. The rotor geometry has been optimized with the multiple aims of achieving the maximum average torque with the lowest torque ripple and to simplify the PM insertion. The motors performance have been evaluated by means of finite elements analysis considering the rotor with and without the PM effect.Pubblicazioni consigliate
