Stator and motor
First Claim
1. A stator comprising;
- a cylindrical-shaped stator core including a plurality of teeth projecting in a radial direction of the stator core;
a plurality of coils formed by a plurality of wires being wound around each of the plurality of teeth;
a plurality of bus rings arranged at an axially end portion of the stator core and each electrically connected to predetermined coils of the plurality of coils;
a plurality of wire pulled-out portions formed on both ends of the coil and pulled out towards the bus ring; and
a plurality of connection terminal portions integrally formed on the respective bus rings in such a manner that the connection terminal portions are arranged at respective predetermined intervals in a circumferential direction of the stator core and each extending towards the wire pulled-out portion;
a tip end portion of the connection terminal portion being bent so as to form a substantially U-shape for pinching the wire pulled-out portion.

Abstract
A stator includes a cylindrical-shaped stator core including multiple teeth projecting in a radial direction of the stator core, multiple coils wound around each of the multiple teeth, multiple bus rings arranged at an axially end portion of the stator core and each electrically connected to each of the multiple coils, multiple wire pulled-out portions formed on both ends of the coil and pulled out towards the bus ring, and multiple connection terminal portions integrally formed on the respective bus rings in such a manner that the connection terminal portions are arranged at respective predetermined intervals in a peripheral direction of the stator core and each extending towards each wire pulled-out portion. A tip end portion of the connection terminal portion is bent so as to form a substantially U-shape for pinching the wire pulled-out portion.

11. A stator core comprising:
-
a cylindrical-shaped stator core including a plurality of teeth projecting in a radial direction;
a plurality of coils formed by a plurality of wires being wound around each of the plurality of teeth;
a first bus ring including a first connection terminal portion electrically connected to a first wire pulled-out portion on a winding start side of the coil;
a second bus ring including a second connection terminal portion electrically connected to a second wire pulled-out portion on a winding end side of the coil;
an insulating member disposed between the coil and the stator core and including a turning portion that includes a turning point where the first wire pulled-out portion and the second wire pulled-out portion are turned to a circumferential direction of the stator core, a first holding portion for holding the first wire pulled-out portion turned to the circumferential direction of the stator core in an opposite direction to a winding direction of the coil by means of the turning portion, a second holding portion for holding the second wire pulled-out portion turned to an opposite direction to a direction in which the first wire pulled-out portion is guided by means of the turning portion;
wherein the first connection terminal portion extends towards the first wire pulled-out portion from a main body of the first bus ring while a tip end portion of the first connection terminal portion forms into a substantially U-shape opening towards the stator core, the U-shaped portion engaging with a portion of the first wire pulled-out portion arranged between the turning portion and the first holding portion, and the second connection terminal portion extends towards the second wire pulled-out portion from a main body of the second bus ring while a tip end portion of the second connection terminal portion forms into a substantially U-shape opening towards the stator core, the U-shaped portion engaging with a portion of the second wire pulled-out portion arranged between the turning portion and the second holding portion. - View Dependent Claims (12, 13, 14, 15, 16, 19, 20)
