Rare earth permanent magnet (PM) motors have high efficiency and torque density, but they have the drawback of a high material
cost. There is a great interest in designing PM machines without adopting such rare earth PMs. Thus, this paper proposes the use of
ferrite instead of rare earth PMs to decrease the material cost. The models with structures are discussed that increase the Torque density.
Discussed model is considered efficiency, reduce costs and winding temperature of the motor using scale factor. Thus, a motor using
ferrite with the proposed structure can replace a motor using rare earth PMs. And the motor is fabricated and tested in order to verify
its feasibility.
