Title:
DYNAMO-ELECTRIC MACHINE STATOR
Document Type and Number:
Japanese Patent JP2015050912
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the axial length of the coil end of a stator coil formed by bonding conductor segments, in a dynamo-electric machine stator.SOLUTION: A stator 10 includes a stator core 12 having a plurality of slots 18u, 20u, 18v, 20v, 18w, 20w, and a plurality of stator coils 22u, 24u, 22v, 24v, 22w, 24w formed by bonding a plurality of conductor segments 26, 28 inserted into the plurality of slots 18u, 20u, 18v, 20v, 18w, 20w on the outside of one end face of the stator core 12 in the axial direction at joints C1, C2, and wound around the stator core 12 side by side in the circumferential direction, in distributed winding. The joints C1, C2 of stator coils 22u, 24u, 22v, 24v, 22w, 24w inserted into slots adjacent in the circumferential direction are arranged differently from each other in the radial direction.
