An Effort to Replace Interior Permanent Magnets Rotors with Assisted Reluctance Rotors
Description
The scarcity and increasing price of rare earth magnets, forces researchers to design permanent magnet machines with a smaller volume of rare earth magnets. The aim of this paper is to propose and analyze a PM-less machine with respect to an interior permanent magnet synchronous machine (IPMSM). The IPMSM considered as reference machine in this paper is used in assisted power steering systems in the automotive industry. The proposed topology has the same stator (lamination, cross-section) and a rotor with flux barriers and permanent magnets.
