Modeling and simulation of 8/6 pole switched reluctance motor with closed loop speed control

A switched reluctance (SR) motor has a doubly salient pole structure. A stator has concentrated windings on each pole, while a rotor is only made of iron core. Therefore, the SR motor is expected as a low cost, extremely robust, variable speed motor. The performance of the SR motor greatly depends on magnetic properties of core material since it consists of only laminated-core and windings. However, some of its disadvantages are noise, torque ripple and low torque per unit volume. In this paper mathematical modeling of switched reluctance motor is carried out various equations of SRM are clearly described. In this paper we have developed simple SRM model without nonlinearities and saturation effects. The proposed model is operated in open loop and further it is operated in closed loop. PI controller is employed for closed loop operation. Finally MA TLAB/Simulink based model is developed and simulation results are presented.
