Why this course?


Switched Reluctance Motor is one of the oldest electric motor that is competing since 180 years. Availability of sophisticated and economical power electronics technology gave rebirth to the most efficient and robust motor -SRM. Due to higher efficiency, magnet-less operation and simple mechanical structure, SRM becomes most preferable electric motor for latest electric vehicle applications. Recently advanced version of SR technology have been used to power Tesla Model 3 electric car and claimed significant increased in range (efficiency) compared to induction motor used in Model S.

SRM offers numbers of benefit like higher efficiency, less weight, mow cost, reduced manufacturing process time, wide constant power region, fault tolerant operation and superior performance even at comparative higher temperature.

This course explains each and every fundamental detail about switched reluctance motor and drive. Starting from fundamental operation of SRM, it covers extreme detail about each parameters and terms related to Motor, converter as well as controller. It includes SRM geometries, magnetic characteristics, inductance profile, angular parameters, torque equation, torque speed characteristics, converter topologies, speed control, closed-loop control, braking, regeneration, torque ripple, acoustic noise etc.

Animation and visualization developed for this course will help in learning with easy.


I am Dr. Jignesh Makwana. I am working of SRM since 2005 and my first research paper on SRM converter was published in 2008. Then after I have published numbers of research articles on SRM in various journals, conferences and books. Other than theory and publications, I have worked intensively on SRM hardware as well as simulations. I have also provided consultancy service to the industry for designing and manufacturing SRM, converter and controller.

This fundamental course is compilation of all the important aspects of switched reluctance motor drive in very well organized manner and easy to understand with visual animations. It will give you the initial boost by clearing your all doubt about switched reluctance motor and drive. Even if you know few basic things about SRM ,I assured that you will learn so many more important things.
