摘要：

The paper presents the field-circuit and circuit modelling of the no-load and load losses in the core of high-speed induction motor. The machine parameters and load characteristics are calculated at supply frequencies of 50, 100 and 200 Hz. In the field-circuit approach the distribution and changes of magnetic flux density in the motor are computed using a time-stepping finite element method. The Discrete Fourier Transform is used to analyze the magnetic flux density waveforms in each element of the motor model. The influence of load condition on core losses has been observed. The results are compared with measurements.
