Design of a low-cost concentric winding permanent magnet assisted synchronous reluctance motor drive

In this paper, various key points in the rotor design of a low cost permanent magnet assisted synchronous reluctance motor (PMa-SynRM) are introduced and their effects are studied. Finite element approach has been utilized to show the effects of these parameters on the developed average electromagnetic torque and total d-q inductances. Effect of concentric winding on overall efficiency and design criteria is investigated. Effectiveness of the design procedure is validated by presenting simulation results.
