Modeling and Simulation of Switched Reluctance Motor with Internal Fault Capability

Abstract

Switched reluctance motors (SRMs) are attaining increasing interest as they are powerful candidates for several industrial applications, especially electric vehicles (EVs). And since, SRMs cannot run directly from AC or DC supply. SRMs require a commutation process that includes a closed-loop current control accordingly to the rotor position. Internal faults in motor coils directly affect the control system and output power. This, in turn, causes overheating and lower efficiency. Besides, it causes fast degradation of motor life. Therefore, this paper presents a modeling and simulation for SRMs, including internal faults. The simulation of SRM is not a simple task to achieve. Hence, the involvement of internal faults increases the challenge. Besides, this paper gives a detailed analysis of machine performance with internal faults. The analysis gives a very good help in understanding the problem and seek for solutions.
