Document Type and Number:
WIPO Patent Application WO2010110082
Kind Code:
A1
Abstract:
Disclosed is a bus ring which is fixed along the axial end face of the stator of a dynamo electric machine, wherein the stator (3) has a plurality of stator teeth (7) arranged in the circumferential direction, and a winding (17) which is wound around the stator teeth (7), the bus ring (5) has a conductive wire (9) curved in the shape of an arc having a diameter smaller than the diameter of the stator (3), and a gate-shaped bend (11) projecting in the axial direction, and the winding (17) is connected with the bend (11). A fixing structure (23) of a bus ring is configured in such a manner that an insulator (25) interposed between the stator teeth (7) and the winding (17) is projected in the axial direction from the end face (1) of the stator (3), and then the insulator (25) is made to advance to the inside of the conductive wire (9) of the bus ring (5).
