Abstract

The steady state magnetic and thermal performance of a wound-field cylindrical rotor synchronous motor under loss minimization control is investigated. The calculated magnetic field waveforms are presented and it is shown that loss minimization control decreases the magnetic saturation. It is also proved that although the optimal stator current is increased, the temperature is decreased in all parts of the motor. Theoretical and experimental results are presented to verify the operational improvements
