Title:
POWER COLLECTION AND DISTRIBUTION RING AND ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP2015046957
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power collection and distribution ring which allows for easy connection of a bus ring and a winding, without using a connection terminal for connection with the winding.SOLUTION: A power collection and distribution ring 4 includes first through third bus rings 41-43. Connections 41a, 42a, 43a arranged in the axial direction, and connected with a winding 32 by bending a linear conduction member, and coupling parts 41b, 42b, 43b for coupling the connections 41a, 42a, 43a in the circumferential direction are provided in the first through third bus rings 41-43. The distances in the axial direction between the connection positions 41c, 42c, 43c with the winding 32 and the coupling parts 41b, 42b, 43b are differentiated, respectively, in the first through third bus rings 41-43, so that the connection positions 41c, 42c, 43c with the winding 32 are equalized in the axial direction at the connections 41a, 42a, 43a.
