摘　　要：电机变频使用的特殊性,使得变频调速电机启动过程中容易出现共振现象,应充分考虑电动机构件及整体的刚性,预防电动机出现振动及噪声问题,变频电机的设计能否满足用户的要求显得尤为重要,所以定子固有频率的计算是不可缺少的环节。The particularity of the frequency conversion of the motor makes the resonance phenomenon prone to occur in the starting process of the frequency conversion motor.The rigidity of the motor components and the whole should be fully considered to prevent the vibration and noise of the motor.The variable frequency motor designed to meet the requirements of users is particularly important,so that the calculation of inherent frequency of the stator is an indispensable link.
