Abstract

This paper presents summarized electromagnetic and thermal design of interior permanent magnet motor for a low-floor tram TMK 2200. Motor geometry is optimized for maximum torque density using differential evolution algorithm. The influences of winding configuration on power losses and thermal transients in the motor during one driving cycle of the tram have been analyzed. The results indicate that an optimal number of turns per slot and parallel paths can be found to yield minimum temperatures in various parts of the motor considering the intermittent character of the load.
