Nowadays, switched reluctance motors (SRMs) attract more and more attention. Switched reluctance machines have emerged as an important technology in industrial automation. The Switched Reluctance Motor implements a three-phase switched reluctance motor (SRM). The stator has three pole pairs, carrying the three motor windings, and the rotor has several nonmagnetic poles. The motor produces a torque by energizing a stator pole pair, inducing a force on the closest rotor poles and pulling them toward alignment. They represent a real alternative to conventional variable speed drives in many applications. It not only features a salient pole stator with concentrated coils, which allows earlier winding and shorter end turn than other types of motors but also features a salient pole rotor, which has no conductors or magnets and is thus the simplest of all-electric machine rotors. Simplicity makes the SRM inexpensive and reliable, and together with its high-speed capacity and high torque to inertia ratio, makes it a superior choice in different applications. This design attempts to create a MATLAB model 2007b version(available in Matlab toolbox) of SRM. Simulation results also prove the exactness of the model.
