Switched Reluctance Machine Design — Lesson 1

This lesson covers the design principles of a switched reluctance machine, focusing on specifications like power, torque, speed, efficiency, electric loading, and magnetic loading. It explains the working principle of switched reluctance machines, which is based on electromagnetic attractions and repulsions of magnetic fields. The lesson also discusses the sizing equations used to analyze the volume product for a given power rating. It further elaborates on the torque equation and the structural view of a switched reluctance machine. The lesson concludes with an explanation of the power equation in relation to electric loading, magnetic loading, volume product, and rotor speed.
