高速电机振动故障影响因素及控制措施

Influencing Factors and Control Measures of High Speed Motor Vibration Fault

振动超差是电机特别是高速电机例行试验过程中遇到的最常见的不合格项之一。影响电机振动的因素非常多,通过试验测量得到的数据分析,无法精确地找到引起振动的根本原因,往往需要反复的试验及电机解体、复装等过程。文章依次介绍了试验、装配、配件等三类影响电机振动的因素及振动故障处理方法。

Vibration tolerance is one of the most common nonconforming items encountered during routine testing of motors, especially high-speed motors.There are many factors that affect the vibration of the motor.Through the analysis of the data obtained by the test,the root cause of the vibration can not be found accurately,and it is often necessary to repeat the test and the process of disassembling and disassembling the motor.This paper introduces three factors,such as test,assembly and accessories,which affect the vibration of the motor and the vibration fault treatment method.
