Derivation method of torque and voltage equations based on the structure of synchronous motors

Abstract

For the research and/or development of motors and their control methods, it’s necessary to obtain torque and voltage equations of the motors from their structure. This paper presents the derivation method of torque and voltage equations of IPMSM (Interior Permanent Magnet Synchronous Motor) and FMSM (Flux Modulating Synchronous Motor) from their basic structure. Fleming’s law is applied to derive torque equation.
