可逆轧机主电机的振动分析和抑制研究

Study on Vibration Analysis and Suppression of the Main Motor of Reversible Rolling Mills

在鼠笼型异步电动机转子磁势与振动分析的基础上,结合可逆轧机主电机的实际振动数据,分析得到可逆轧机主电机的异常振动是由转子磁势与电机的定子主板外侧侧板共振引起的。根据现场实际情况,提出了抑制振动的策略方案。

Based upon the analysis on the rotor mag-netic potential and vibration of the squirrel cage asynchro-nous motor and combined with the actual vibration data of the main motor of the reversible rolling mill,the analyzed result is achieved that the abnormal vibration of the main motor of the reversible rolling mill is caused by the reso-nance between the rotor magnetic potential and the outer side plate of the stator main plate of the motor.According to the actual situation of the site,a strategy for suppressing vibration is put forward.
