Abstract

In a stator, a coil is wound around a stator core. A guide member is provided on one side of the stator core in the axial direction and guides the terminal line of the coil in the circumferential direction at a position overlapping the coil in the axial direction. The terminal line of a first coil includes a first axial extension part led out to one side in the axial direction. The terminal line of a second coil adjacent to the first coil on one side in the circumferential direction includes a second axial extension part led out to one side in the axial direction. A first position, which is a base end of the first axial extension part, and a second position, which is a base end of the second axial extension part, are set to the positions where are different in the radial direction.

Claims (17)

1. A stator comprising:

a stator core;

coils of multiple phases that are wound around the stator core via an insulator, and including a plurality of terminal lines;

a guide member that is disposed on one side of the stator core in an axial direction, and being configured to guide for guiding the plurality of terminal lines of the coils in a circumferential direction at a position overlapping with the coils in the axial direction, wherein

the coils includes a first coil and a second coil adjacent to the first coil on one side in the circumferential direction,

a terminal line of the first coil includes a first axial extension part led out from the first coil to one side in an axial direction of the guide member, and a first routing part routed from a tip end part of the first axial extension part to one side in the circumferential direction by the guide member,

a terminal line of the second coil includes a second axial extension part led out from the second coil to one side in the axial direction of the guide member, and a second routing part routed from a tip end part of the second axial extension part to an other side in the circumferential direction by the guide member,

a first position, which is a base end of the first axial extension part, and a second position, which is a base end of the second axial extension part, are set to positions where are different in a radial direction.

2. The stator according to claim 1 , wherein

the guide member has a notch that includes a guide part extending radially inward from an outer end in the radial direction of the guide member, penetrates in the axial direction, and guides the first axial extension part and the second axial extension part to one side in the axial direction, and

a first holding part cut out on one side in the circumferential direction and a second holding part provided on the other side in the circumferential direction are provided at an inner end in the radial direction of the notch.

3. The stator according to claim 2 , wherein

the guide part has an inclination guide part that is inclined toward the circumferential direction other side while being extending to radially inner side from radially outer side.

4. The stator according to claim 2 , wherein

a partition part extending in the axial direction is provided outside in the radial direction of at least one of the first holding part and the second holding part.

5. The stator according to claim 1 , wherein

a position of a base end of the first axial extension part and a position of a base end of the second axial extension part are set to a position of end part in the radial direction of the coil.
