Abstract

This paper addresses the thermal network improvement in a 315 kW high-voltage solid rotor permanent magnet synchronous motor, with a hybrid air-cooling system, by the proposed thermal barrier. The multi-coupled fields, as electromagnetic fields, fluid field, and thermal fields of the machine are investigated via the finite-element analyzing. Looking at the reduction of magnet working temperatures, a thermal barrier approach is proposed to re-regular the heat transmission network, so as to control the temperature rise in magnets. The variations of loss and temperature distributions in machine affected by the thermal barrier are studied. The obtained results, be verified by the test date, shows that the thermal barrier has of effectiveness in reducing magnet working temperature, which is up to 15 °C in case study.
