Rotating electrical machine and method for producing such a machine

Rotating electrical machine and method for producing such a machine

A rotating electrical machine has a rotor ( 11 ), which rotates about an axis ( 13 ) and is surrounded concentrically by a stator ( 12 ) having a stator winding ( 30 ) inserted into a stator body ( 21 ), the stator winding ( 30 ) including, in a concentric arrangement, a lower layer ( 16 ), which is...

description A rotating electrical machine has a rotor ( 11 ), which rotates about an axis ( 13 ) and is surrounded concentrically by a stator ( 12 ) having a stator winding ( 30 ) inserted into a stator body ( 21 ), the stator winding ( 30 ) including, in a concentric arrangement, a lower layer ( 16 ), which is more remote from the axis, and an upper layer ( 17 ), which is closer to the axis, of axially extending winding bars ( 14 ), which emerge from the stator body ( 21 ) at the ends of the stator ( 12 ) and are arranged, within an end winding ( 15 ), with their bar ends ( 23 ), on two concentric circles in pairs one above the other in the radial direction. With such a machine, simplified production of the stator winding ( 30 ) with, at the same time, a high dielectric strength is achieved by virtue of the fact that in those winding bars ( 14 ) of a pair which belong to different phases within a phase segregation, radial spreading ( 18 ) of the bar ends ( 23 ) is provided so as to increase the radial distance between the different phases.
