Design of SRM considering dual drive modes

Due to the requirement of two operational modes, washing and spinning modes of the washing machine, design of the motor to meet the required torque and efficiency in each mode is not an easy task. To achieve the requirements, a 24/16-pole outer rotor type switched reluctance motors (ORSRM) are proposed. To choose the most suitable design parameters for the washing machine, the static toque of the SRM is compared based on the FEM analysis. The selected motor is obtained for high and wide toque than other types of the motor. Further, the pole shape and arc is optimized to get higher torque and lower torque ripple. To verify the proposed structure, the prototype is manufactured. Finally, the simulation and experiment results verify the validity of the proposed structure.
