Rotor Cage Losses of an Inverter-Fed PMSM investigated with FEM
2003 (English)In: Proceedings of the European Conference on Power Electronics and Applications, EPE´03, 2003Conference paper (Refereed)
In the design of a compact inverter-fed buried permanent magnet synchronous motor, the high-frequency losses of the sparse rotor cage - which are difficult to predict - were assumed to be small. To investigate these ohmic high-frequency losses of the rotor cage, fixed-speed time-stepping 2D-FEM calculations have been carried out. The losses due to only the magnets, magnets and sinusoidal currents, high-frequency currents etc., and the actual currents are presented. The actual current wave-forms were obtained from measurements on the manufactured prototype motor.
