Abstract :
An improved core loss model of surface mount permanent magnet electric motor for electric vehicle application is proposed, which the loss coefficients are functions of frequencies. The core loss curve under a wide range of frequency between 100-1000 Hz and inductions from 0 to 1.5 T is obtained by means of experimental test. The calculated data are compared with the experimental result. Based on the proposed method, the loss distribution within a driving motor for electric vehicle under complex driving duty cycle is obtained.
