MOTOR
First Claim
1. A motor comprising:
- a stator including;
a stator core including a core back having a substantially circular shape centered on a center axis, and a plurality of tooth portions extending radially inwardly from the core back and arranged in a circumferentially spaced manner;
a plurality of insulators covering at least a portion of the stator core so as to insulate at least the portion of the stator core; and
a plurality of coils each of which is defined by a multilayer structure of a wire wound around each of the tooth portions via the insulator;
a bus bar arranged axially above the stator and including a plate support;
a first conductor plate supported by the plate support and having a plurality of first terminals to which first end portions of wires extracted from the plurality of coils are to be connected; and
a second conductor plate supported by the insulator and having a plurality of second terminals to which second end portions of the wires are to be connected;
whereinthe second end portions of the wires are connected to a neutral point via the second conductor plate.

Abstract
A motor includes a stator including a core back having a circular or substantially circular shape, a plurality of tooth portions extending radially inwardly from the core back, a plurality of insulators covering the tooth portions, a plurality of coils formed by winding wires around the tooth portions via the insulators. The motor also includes a bus bar arranged axially above the stator. The bus bar supports a first conductor plate having a plurality of first terminals to which first end portions of the wires from each phases of the coils are connected. The insulators include a guiding groove and support therein the second conductor plate to which second end portions of the wires are connected. Through the second conductor plate, the second end portions of the wires are connected to the neutral point.
