Abstract
The design and performance of a permanent magnet assisted synchronous reluctance motor (PMASynRM) is investigated using finite element method. The motor is called PMASynRM when the share of reluctance torque is significant compared to the PM electrical torque. The advantages of adding PMs to the synchronous reluctance motor rotor construction are the increased motor power factor and thus reduced motor stator ohmic losses. The ohmic losses represent the majority of the motor total losses. The advantage of reluctance torque is the decreased need of expensive permanent magnet (PM) material, which makes this solution thus cheaper than the respective permanent magnet motor. The advantages of PMASynRM compared to the induction motor (IM) are the synchronous rotation speed, possibility of sensorless rotation control, higher power factor and better efficiency.
