提高端盖刚度降低电机轴向振动

Improvement of Rigidness of Endshields to Reduce Axial Vibration of the Motor

在Y、YKK、YKS系列高压电动机的制造过程中,经常出现振动超标现象,尤其轴向振动突出。通过观察和检测数据分析,电动机的平板式钢板端盖改为盘式铸铁端盖,可提高端盖刚度,降低电机轴向振动。

During production of Series of Y,YKK and YKS high voltage motors,the circumstance that the vibration data exceeded that of the standard occurred frequently,especially the axial vibration. By means of observing the operation and analysis on the test data,the plate steel end shield was replaced by the cast iron disc end shield to reduce axial vibration.
