摘要：
When calculating the can loss, the finite element method considering time harmonics needs the working current waveform, and the analytical method considering the harmonic adopts superposition principle. Based on the power conservation law, this paper proposes a method to obtain the can loss that can take into account the time harmonics from inverter and the harmonic loss. The method can obtain the calculation accuracy similar to that of the finite element method without relying the current waveform of the motor, and has the advantages of simple calculation and saving time. In addition, the method proposed in this paper is used to analyze the can loss under different loads, and the influence law of the can parameters on the can loss is explored. It provides a reference for the determination and optimization of the can loss of the canned permanent magnet synchronous motor under non-sinusoidal excitation.
