Abstract

In this paper, a six-phase switched reluctance motor for applications such as vertical transportation in a linear elevator is considered. The driving force ripple in a linear switched reluctance is high and the use of these machines in low speeds are accompanying with high speed ripple. In fact, the proposed construction consists of the combination of two 3-phase series linear switched reluctance motors which make a 6-phase structure in order to provide a better torque specification. In this paper we tried to reach a better speed profile in low speeds (0.5 m/s up to 1 m/s) which is normally the case in elevators. The simulation results show the superiority of the proposed structure over conventional structure of the switched reluctance motors. The proposed structure reduces the speed ripple from 16.8% to 1.24% at 0.5 m/s. This result shows the high performance improvement of the 6-phase structure of the motor.
