Abstract: This paper investigates eddy current and proximity losses in windings of different high speed brushless permanent magnet machines. Several papers have already addressed this but in this paper different topologies and winding connections are investigated to give a comparative study. This is done different operating speeds and loadings. This is important because more machines are being developed to address the requirements of applications such as automotive electric drives. These often operate at the thermal limits of the machine at high current density during the transient torque cycling.
