Title:
COIL SEGMENTS, METHOD FOR MANUFACTURING COIL SEGMENTS, WIRE ROD FOR COIL SEGMENTS, AND STATOR
Document Type and Number:
WIPO Patent Application WO/2013/061904
Kind Code:
A1
Abstract:
Provided are coil segments that can improve motor efficiency and prevent flux leakage and eddy currents effectively. Said coil segments (4a, 5a) are placed in the radially innermost parts of slots (3) formed in the inner surface of the annular core (2) of a stator (1) in a dynamo-electric machine, said stator comprising said annular core and a plurality of layers of rectangular-wire coils. Said coil segments, which face a rotor, are each divided into a plurality of wire parts (11, 12, 13) in the circumferential direction of the annular core. In each coil segment, said plurality of wire parts are joined together into a single unit in coil end parts (E1, E2) that protrude from those slots.
