Abstract
In a V-phase stator component in which a plurality of V-phase insulators are separate from each other, the V-phase insulator corresponding to a second V-phase winding includes a flange portion which is provided with a first guide groove for guiding a winding start portion led out of the second V-phase winding and connected to a crossover wire portion, and a second guide groove for guiding a winding end portion led out of the second V-phase winding and connected to a crossover wire portion. The first and second guide grooves are provided with respective retaining portions formed so that an opening width is smaller than the diameter of the conductor wire.

A stator comprising:
- a stator core including a plurality of core segments annularly disposed in a circumferential direction;
- a plurality of stator components, wherein
- each of the stator components comprises:
- a plurality of separated core elements that are not adjacent to each other in the circumferential direction, at least two core segments among the plurality of core segments serving as the plurality of separated core elements;
- a plurality of insulators that are provided to the respective plurality of separated core elements, elements;
- and
- a plurality of windings that are concentrically wound around the respective plurality of separated core elements via the corresponding insulators, and are supplied with currents having the same phase as each other,
- in each of the stator components, the plurality of windings are formed of a single conductor wire, with the plurality of windings being connected to each other via a crossover wire portion which is part of the single conductor wire,
- at least one of the plurality of stator components is a first stator component in which the plurality of insulators are separate from each other,
- the insulators of the first stator component each include a guide groove for guiding a leader led out of a corresponding one of the windings and connected to the crossover wire portion,
- the guide groove includes an opening in which the leader is inserted in the guide groove in a direction orthogonal to a longitudinal direction of the leader,
- the guide groove includes, at at least a part of the guide groove in a direction in which the guide groove extends, a retaining portion in which a width of the opening is smaller than a diameter of the leader, and
- a part of the plurality of stator components is a second stator component, the second stator component including an integrated molded member in which the plurality of insulators are integrally formed with a connecting portion connecting between the plurality of insulators,
- wherein a remaining part of the plurality of stator components is not integrally formed with the connection portion.
