Determining the Volume Optimal Parameter Values for Multi-Phase Permanent Magnet Synchronous Motors with Switchable Coil Configuration

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.
