Abstract
In a method of manufacturing a stator of a vehicle AC generator, U-shaped conductor segments having a turn portion and a pair of forked in-slot portions are formed so that the radial width of each conductor segment can be larger than the radial depth of each slot of a stator core. The in-slot portions of the conductor segments are compressed from radially outside and inserted into each slot in an axial direction of the stator core so that the conductor segments can provide a spring-back force in the slots. Then, the U-shaped conductor segments are welded at ends of the in-slot portions in a prescribed pattern.
Claims5
A method of manufacturing a stator that includes a stator core having a plurality of slots and a stator winding, said method comprising the steps of:
- forming U-shaped conductor segments each having a turn portion and a pair of forked in-slot portions so that a radial width of each said conductor segment is larger than a radial depth of said slots;
- compressing said in-slot portions of said conductor segments from radially outside;
- inserting said compressed in-slot portions of said conductor segments into each of said slots in an axial direction of said stator core so that said conductor segments provide a spring-back force;
- and
- welding said U-shaped conductor segments at ends of said in-slot portions in a prescribed pattern.
