Design of Switched Reluctance Machine - I — Lesson 3

This lesson covers the design equations for the stator of a switched reluctance machine. It explains how to calculate the volume of a machine, the number of turns per phase, the stator phase current, and the cross-sectional area of the conductors. The lesson also discusses how to select the number of phases and poles in a switched reluctance machine, considering factors such as power, torque density, fault tolerance, starting capability, and cost. It further elaborates on how to calculate the slot height, pole height, slot area, and back iron thickness. The lesson concludes with the calculation of flux densities at different parts of the iron.
