Abstract :
The characteristics of MW-class high speed induction motors are analyzed by 3-D finite element methods. First, several approximations are applied to the analysis in order to reduce the computation time without the deterioration of accuracy. Then, the calculated characteristics are compared with the experimental results in order to verify the proposed method. Finally, the loss generation mechanism of the motor is revealed by analyzing the harmonic electromagnetic fields. It is clarified that the combination of the 2-D and the one rotor slot 3-D finite element methods is suitable for the analysis of the motors. By using this method, the largest harmonic loss component of the motor is successfully specified.
