【Abstract】 In this paper,the analytical expression of the phase current of high-speed permanent-magnet brushless DC motor(HSPMBLDCM) was formulated considering the current commutation,as well as the structure of artificial neural network of the real back electromotive force.On the basis of these,a precise steady-state model of HSPMBLDCM was built.With this model the performance of motor are analyzed accurately and widely.更多还原
