摘要： In a rotating machinery having armature windings constituted by a lot of strands, when the armature winding is constituted by four layers, a step number of the strands becomes half with respect to two layers of armature windings so as to facilitate manufacturing an armature winding of 540 degree transposition in which a transposition pitch is elongated and a circulating current loss is reduced, but since an output voltage becomes twice, for securing a voltage limit value caused by an isolation resisting force, one layer of armature windings are constituted by sub windings separated into at least two layers in a vertical direction, a transposition is independently applied to each of the sub windings, the sub windings are connected to the armature windings of the other slot while keeping an isolation of the sub winding at an armature winding end region by at least two connecting methods, and the sub winding constructs a parallel circuit by the armature windings of a plurality of slots.

摘要： In a stator core support structure in a conventional rotating electric machine, it has been difficult to set the circumferential and radial stiffnesses with which elastic bars support a stator core, to appropriate values in view of a relationship between transmission of torque and vibration prevention. In order to solve the above problem, sectional shape of elastic support bars is formed as rectangular, elliptic, rhombic or the like, and accordingly, the ratio between circumferential and radial stiffness of the elastic support bars can be changed.
摘要翻译：在传统的旋转电机的定子铁芯支撑结构中，考虑到扭矩传递和防振动之间的关系，难以将弹性杆支撑定子铁心的周向和径向刚度设定为适当的值。为了解决上述问题，弹性支撑杆的截面形状形成为矩形，椭圆形，菱形等，因此可以改变弹性支撑杆的周向和径向刚度之间的比例。
