Abstract
A bus bar extended end portion of a bus bar that projects from a main body of a bus bar module and a coil conductor extended end portion extend in the same direction, and are disposed adjacent to each other. The respective distal ends of the coil conductor extended end portion and the bus bar extended end portion are welded to each other. The coil conductor extended end portion and the bus bar extended end portion are also fixed to each other at a position away from the weld.
Claims7
A stator for a rotary electric machine, the stator comprising:
- a stator core;
- a plurality of partial coils made from coil conductors, the plurality of partial coils being mounted on the stator core;
- and
- a plurality of bus bars connecting the coil conductors of the partial coils to form a coil group, the plurality of bus bars being integrated with each other to form a module main body, and the plurality of bus bars including end portions extending from one side surface of the module main body and a side surface of the module main body opposite to the one side surface;
- wherein the module main body is disposed adjacent to the coil group in a rotational axis direction of the rotary electric machine;
- the coil conductors include a conductor extended portion provided at end portions of the coil conductors to extend in the rotational axis direction and in a direction away from the coil group;
- the bus bars include a bus bar extended portion provided at the end portions of the bus bars to extend in the rotational axis direction and in the direction away from the coil group;
- the conductor extended portion and the bus bar extended portion are disposed adjacent to each other;
- the conductor extended portion and the bus bar extended portion include a weld provided between the conductor extended portion and the bus bar extended portion;
- and
- the conductor extended portion and the bus bar extended portion are adhered to each other with a resin at a position away from the weld, or brought into tight contact with each other with a resin solidified in conformity to a surface of the bus bar extended portion at a position away from the weld to support the module main body by the conductor extended portion.
