Abstract
An armature of an electric rotating machine includes an armature core provided with plural divided cores arranged in a circumferential direction. A salient pole is provided in each of the plural divided cores. A coil winding is wound around each salient pole. A convex winding configuration of the coil winding is formed so as to project on an adjacent salient pole side over a boundary line between adjacent divided cores. A concave winding configuration of the coil winding is formed so as to be hollow from the boundary line so as not to interfere with the convex winding configuration.

An armature of an electric rotating machine comprising:
- an armature core including plural divided cores arranged in a circumferential direction;
- a salient pole provided in each of the plural divided cores;
- a coil winding wound around each salient pole;
- a convex winding configuration of the coil winding formed so as to project on an adjacent salient pole side over a boundary line between adjacent divided cores;
- and
- a concave winding configuration of the coil winding formed to be hollow from the boundary line so as not to interfere with the convex winding configuration.

- a salient pole provided in each of the plural divided cores;
- a coil winding wound around each salient pole;
- a convex winding configuration of the coil winding formed so as to project on an adjacent salient pole side over a boundary line between the plural divided cores;
- and
- a concave winding configuration of the coil winding formed to be hollow from the boundary line so as not to interfere with the convex winding configuration.
A manufacturing method for an armature of an electric rotating machine comprising:
- providing an armature core having plural divided cores with a salient pole for each of the plural divided cores;
- winding a coil wire around the salient pole of the plural divided core so as to form a convex winding configuration which is formed to project over a boundary line and to form a concave winding configuration which is formed to be hollow from the boundary line;
- and
- winding a coil wire around the salient pole of adjacent divided cores so as to form a concave winding configuration which is formed to be hollow from the boundary line so as not to interfere with the convex winding configuration of the plural divided core and to form a convex winding configuration which is formed to project form the boundary line so as not to interfere with the concaved winding configuration of the plural divided core.
