| Abstract |
In this paper, a new configuration for a three phase Switched Reluctance (SR) Machine is introduced. The proposed machine consists of two magnetically independent stator and rotor layers, where each stator layer includes six salient poles with windings wrapped around them, while the rotor comprises of four salient poles with different arc lengths and no windings. There is a stationary reel, which has the field coils wrapped around it and is placed between the two-stator sets. The distinctive point of this proposed machine is its ability to work in motor and generator modes, which leads to hybrid operation. The mathematical model is carried out to obtain the characteristics of this motor. The torque ripple reduction is done as well by shifting the rotor in one of sets. In a proposed method the rotor angle shifting is used to increase overlap between rotor and stator poles. Subsequently, machine operation as switched reluctance motor is simulated by Finite Element Method (FEM). |
