Injected Current Effects on Magnetic Field and Torque Characteristic of Home Appliance Switched Reluctance Motor

Switched Reluctance Motor (SRM) has been gaining popularity as a feasible alternative to a brushless dc motor. The injected current on the winding of SRM will have a significant effect on the magnetic field distribution and torque characteristic. This paper discusses multiple current setups to be injected into the winding and observe their effect on motor behavior. The finite element method is applied to analyze both of the magnetic field and generated torque in the motor. The 8/6 450 W SRM commonly utilized for home appliances is investigated as a test machine. The effect on the generated magnetic field and torque control from injected current with variation of phase shift and duty cycle is observed.
