Abstract
In order to study the distribution of the vibration problem caused by the air gap magnetic field in the process of brushless DC motor speed regulation, the finite element method was used to calculate the air gap magnetic field and electromagnetic force excitation at different times and at the same speed and the duty cycle was 1 and 0. 5 respectively. The natural vibration parameters of motor stator core were obtained by structure field calculation, and the vibration of the motor was analyzed. This calculation and analysis method can provide reference for the motor designer.关键词
