  • This contribution suggests an approach to determine the optimal parameter values of permanent magnetflux linkage and saliency ratio of Permanent Magnet Synchronous Motors with multi-phase windingsand coil configuration switching. Therein, their influence on volume is calculated analytically for bothmotor and power electronics in a unified manner identifying promising designs. Of the exemplary designparameters, a maximum volume reduction of 27% can be achieved. An experimental validation supportsthe analytic calculation of the motor torque vs. speed behavior.
