汽车爪极发电机定子模态分析和固有频率计算

摘要

建立爪极电机定子结构的三维有限元模型,利用ANSYS软件对其进行模态分析,计算爪极电机定子的固有频率.结果表明,定子6阶模态对爪极电机噪声和振动的贡献最大.%A 3 D FE model for the stator of claw-pole motor is built, a modal analysis is performed on it u-sing software ANSYS and the natural frequency of motor stator is calculated. The results show that the 6th order mode of stator has the most contribution to the noise and vibration of claw-pole motor.
