Some motors may experience a change in friction loss until the bearings reach a stabilized operating condition. In grease lubricated antifriction bearings, stabilization will not occur until there is no excess grease present in the path of the moving parts. This may require a number of hours of running to completely stabilize the no-load input power. 0 e* B- U2 ]3 V: K # R) i; z. e |2 z是否翻译为:空载输入功率。6 J6 I: @: Z: U! A* N
