In general condition,it should be allowed that eccentric error is larger than ±10% of average air-gap,but over-large eccentric value can produce very much unbalanced magnetic pull,and then increase the deflection of motor shaft,thus critical speed is influenced.
在一般情况下,气隙偏心误差不超过气隙平均值的上下10%是允许的,但过大的偏心值会产生很大的单边磁拉力,导致电机转轴挠度的增加,进而影响电机的临界转速,但许多电机设计人员在计算电机转轴的挠度时,往往忽略单边磁拉力对于挠度的影响,为此,介绍了单边磁拉力产生的原因及对电机转轴挠度影响的计算过程。
