Switched Reluctance Motor (SRM) are widely used in drives market because of its elegant features such as simple arrangement, manufacturing cost, minimal maintenance and wide speed range. Significant investigation has been conducted to lengthen the feasibility of SRM drive technologies in various aspects such as control strategy, torque ripple minimization, an optimal winding arrangement, etc. Even though it has numerous virtues, there are few noticeable issues that occur in SRM. In this paper, the issues like phase open circuit fault, phase-phase short circuit fault, power switch failure, dc link capacitor failure, and encoder faults are discussed using Wavelet Transform (WT) with their experimental results. A multi-phase (10/8 pole) SRM motor is considered to investigate the fault tolerance proficiency and other performance parameters. Initially, a healthy condition of multi-phase SRM is simulated then faults are injected at different phases which are analyzed and validated using MATLAB simulink tool and the same is validated through experimental results. The performance parameters of SRM drive during various faults conditions are analyzed and the impacts of speed and torque are illustrated.

开关磁阻电机（SRM）凭借其优雅的功能（如简单的布置，制造成本，最少的维护和较宽的速度范围）而在驱动器市场中得到广泛使用。已经进行了大量研究以延长SRM驱动技术在各个方面的可行性，例如控制策略，转矩脉动最小化，最佳绕组布置等。尽管SRM具有许多优点，但在SRM中很少出现明显的问题。本文利用小波变换（WT）讨论了开路故障，相线短路故障，电源开关故障，直流母线电容器故障和编码器故障等问题，并给出了实验结果。考虑使用多相（10/8极）SRM电动机来研究容错能力和其他性能参数。原来，模拟多相SRM的健康状况，然后在不同阶段注入故障，然后使用MATLAB simulink工具进行分析和验证，并通过实验结果对其进行验证。分析了SRM驱动器在各种故障条件下的性能参数，并说明了速度和转矩的影响。
