摘要：
An improved analytical model for predicting the rotor eddy current loss in brushless motors equipped with surface-mounted permanent magnets, with due account of the eddy current reaction field, is presented. The model is applied to a brushless dc traction machine, and the predicted rotor loss is compared with the losses deduced from thermometric measurements and from the magnetostatic analytical model. Improved agreement between the predicted and measured rotor loss is achieved over the complete operating speed range.
