Abstract

This paper presents a simplified unbalanced force calculation for switched reluctance machines (SRM) developed based on an electromagnetic circuit model (EMC). Derived from the EMC model, a set of analytical equations for predicting the rotor unbalanced force is achieved as functions of design parameters, which directly provides an intuitive relationship between estimated unbalanced force and design parameters. The accuracy of the developed model was verified by finite-element simulation (FE) and compared with an existing method. It was found that switched reluctance machines with different configurations could have different flux path characteristics. Therefore, an EMC model for unbalanced force calculation should be individually formed and developed for each machine configuration
