Abstract :
This paper investigates the influence of stator slot shape on magnet temperature in a permanent magnet synchronous machine (PMSM). A formal numerical optimization approach using an evolutionary strategy is coupled with time-stepped finite element analysis (FEA) to minimize losses in a surface mounted PMSM. The loss predictions from the FEA model are the used in conjunction with a thermal analysis model to investigate the temperature of the magnets.
