Analysis of the Influence of Material Parameters on Efficiency of Switched Reluctance Motor

The paper deals with analysis of an influence of rotor magnetic materials on the efficiency of switched reluctance motor. Considered were composites, electrical sheets and ferrite. The characteristics inductance and losses as a function of the rotation angle for these materials were presented and compared. For identification of the parameters of the switched reluctance motor, a test bench was constructed. Parameters of electric motor as a function of rotor rotation angle were identified. The equivalent resistance and inductance of the motor as a function of the rotor rotation angle was determined. The least squares method was used to determine the parameters. To measure the efficiency of the reluctance motor, the test bench was constructed. This test bench consist of also a torque sensor and an additional motor as a load.
