Inductance calculations in Switched Reluctance Machines - II — Lesson 6

This lesson covers the process of calculating the inductances of a Switched Reluctance Machine (SRM) using an analytical approach. It explains the concept of flux paths and how to calculate the length of these paths. The lesson also discusses how to find the cross-sectional area with respect to the stator pole region and how to analyze the magnetic equivalent circuit. The lesson further explains how to calculate the reluctance and the flux with respect to the path. Finally, it provides a detailed explanation on how to calculate the inductance in aligned, unaligned, and intermediate positions.
