Abstract

A motor mounted in a vehicle having a winding comprising a flat band-like copper wire is provided. The winding is wound on a projection that extends radially inward of a stator. The winding includes a first band-like section that is adapted to be wound on a radially inward portion of the projection of the stator. The winding also includes a connection section that is continuous with one longitudinal end of the first band-like section and extends radially outward along the radial direction of the projection of the stator. The winding further includes a second band-like section that is adapted to be wound on a radially outward portion of the projection of the stator. One longitudinal end of the second band-like section is continuous with the connection section. The first band-like section extends from a radially inward portion of the connection section and the second band-like section extends from a radially outward portion of the connection section. The first and second band-like sections extend from the connection section in opposite directions.

Claims

1. A motor mounted in a vehicle having a winding wound on a projection of a stator, the projection extending radially inward of the stator, the winding comprising a flat band-like copper wire comprising:

a first band-like section having two longitudinal ends, the first band-like section being adapted to be wound on a radially inward portion of the projection of the stator;

a connection section being continuous with one of the longitudinal ends of the first band-like section and extending radially outward along the radial direction of the projection of the stator; and

a second band-like section having two longitudinal ends, the second band-like section being adapted to be wound on a radially outward portion of the projection of the stator, one of the longitudinal ends of the second band-like section being continuous with the connection section, the second band-like section extending from the connection section in a direction opposite to the direction in which the first band-like section extends from the connection section;

wherein the first band-like section extends from a radially inward portion of the connection section and the second band-like section extends from a radially outward portion of the connection section.

2. The motor according to claim 1, wherein the first and second band-like sections are wound on the projection of the stator in a clockwise direction and a counterclockwise direction, respectively, or a counterclockwise direction and a clockwise direction, respectively.

3. The motor according to claim 1, wherein the second band-like section extends farther in length than the first band-like section.
