2) motor shaft
电机转轴
1.
Motor shaft will suffer a lot of hidden troubles in course, which is mainly caused by flaws of junction with the shaft and ribs in the process of the manufacture and use, so it is particularly important to detect and analyze these flaws regularly, to assess the defects as well as overall motor shaft can provide decision-makers with the necessary basis for decision making.
电机转轴在使用过程中存在各种安全隐患,这主要是由于在制造和使用过程中筋板与转轴的结合处产生的缺陷造成的,所以定期检测并分析这些缺陷就显得尤为重要。
2.
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。

发电机转子轴承系统
5) bearingless motor with a hybrid rotor
混合式转子无轴承电机
6) axially movable motor
