Abstract:
Electrical and mechanical benefits, simple manufacturing and maintenance of switched reluctance motor make it suitable in industrial and home applications, but the most important drawbacks of switched reluctance motor are discontinuous torque and no self-starting in some rotor positions. In this paper a novel rotor structure is presented and optimized in order to increase positive torque region and eliminate dead-zone in high loads. The torque produced in this proposed SRM is divided in two regions and overlapped in two phases periodically. In order to find the best output character and optimal design, two factors, position and angle of cut edge are optimized. To verify the proposed rotor, torque characteristic, flux path and torque ripple has been analyzed by finite element method and compared with conventional 4/2 switched reluctance motor. The proposed motor has a continuous torque characteristic.
Index Terms: Switched reluctance motor; Continuous torque; Finite element method; Dead-zone region.
