Comparison of Switched Reluctance Motor and Double Stator Switched Reluctance Motor A Thesis Submitted to the Graduate Faculty of the University of New Orleans in partial fulfillment of the requirements for the degree of Master of Science in Engineering Electrical Engineering by Nirdesh Neupane B.Tech. Dehradun Institute of Technology, 2014 December, 2018 Acknowledgements I would like to extend my sincere gratitude to my thesis advisor Dr. Ebrahim Amiri for all his support, guidance and encouragement. Without his help this research was nowhere possible. I would like to thank my parents, my parents in laws, my beloved wife Asmita, brothers Sandesh and Aayush, and my sister Prakriti for all the continuous support, motivation and always believing me. Lastly, I would like to extend my appreciation to my friends Bikrant, Rochak, Jyoti and Mahesh for all the encouragement, help, support and giving me extra push whenever I needed. ii Contents List of
