Analytical Inductance Calculation of an Outer Rotor Switched Reluctance Motor

An analytical method to effectively calculate the inductance of a switched reluctance motor (SRM) with an outer rotor has been presented. The winding inductance of both the active section and the end section is evaluated by using the analytical method, which accounts for the influence of core saturation. Results obtained by this method are in close agreement to those obtained by the finite element analysis.
