Design of Axial Type Switched Reluctance Motor Considering Magnetic Characteristics of Soft Magnetic Composite Material

Abstract

In this paper, a design of an axial type switched reluctance motor (SRM) is presented that considers the magnetic characteristics of soft magnetic composite (SMC) material. These characteristics are changed by the press and cutting processes for producing the motor core. It is shown that the magnetic characteristics of the vertical and the parallel flux direction differ according to the direction of the press, and are degraded by the cutting process. The proposed design method can be accurately simulated by using the magnetic characteristics in both the vertical and the parallel flux direction in an axial SRM motor.
