Document Type and Number:
WIPO Patent Application WO/2017/153925
Kind Code:
A1
Abstract:
There is provided a dynamo-electric machine that can provide excellent insulating properties by downsizing coil ends (140). A dynamo-electric machine includes a stator (20) and a rotator (11). The stator (20) has a stator iron core formed with a plurality of slots (420) arranged in a circumferential direction, and a stator coil inserted into the slots (420) of the stator iron core. The rotator is rotatably disposed on the stator iron core with a predetermined gap. The stator coil is provided with an insulating film. The stator coil includes a main coil and a lead wire with an alternating current terminal. The main coil has a plurality of segment coils (28) connected to one another. The segment coil is a conductor in a rectangular cross section formed in advance in a nearly U-shape. The lead wire is led from the slot. The tip end of the segment coil is formed in a trapezoid cross section.
