Dynamoelectric machine as a drive of an electrically driven vehicle

1 . A dynamo-electric machine comprising:

a housing;

a stator located in the housing, the stator comprising a winding system arranged in slots located in a region of an air gap, wherein the winding system is of polyphase design and forms end windings at end faces of the stator;

wherein conductors of electrical phases are arranged axially directly on the end windings;

wherein a conductor of a star-point of the winding system is provided radially above the end windings between the end windings and the housing;

wherein the winding system is composed of tooth-wound coils or chorded coils and the end windings are each provided with a winding cap, wherein the winding cap guides electrical conductors of the winding system and/or phase wires and/or star-point wires and the winding cap comprises an opening that guides a coil output to the conductor of the star-point that runs radially above the end winding;

wherein each winding cap comprises a first flange and wherein the opening is in the first flange;

wherein the opening is an open-sided slot that extends from a first side of the first flange that faces toward the conductors of the electrical phases;

wherein the first flange comprises a recess that is spaced apart from the opening and extends from the first side of the first flange;

wherein each winding cap comprises a second flange opposite the first flange, and wherein the second flange comprises a second recess that is aligned with the recess of the first flange;

wherein the opening extends farther from the first side than the recess extends from the first side, the first flange comprises a cutout disposed opposite the recess, and each winding cap is disposed farther from the housing than the conductor of the star-point of the winding system is disposed from the housing; and

wherein each winding cap comprises a connecting segment that extends from the first flange to the second flange, and the first flange comprises a first panel disposed perpendicular to the connecting segment and a second panel that extends from the first panel in a direction that extends away from the second flange, wherein the opening is disposed in the first panel and the second panel, the recess of the first panel is disposed in the second panel but not the first panel, and the cutout is disposed in the first panel but not the second panel.

2 . The dynamo-electric machine of claim 1 wherein the housing is designed as a cooling jacket.

3 . The dynamo-electric machine as claimed in claim 1 wherein the housing has a cooling system.

4 . The dynamo-electric machine as claimed in claim 3 wherein the housing has axially extending ribs.

5 . The dynamo-electric machine as claimed in claim 1 wherein each winding cap is disposed farther from the housing than the conductor of the star-point of the winding system is disposed from the housing.

6 . The dynamo-electric machine as claimed in claim 1 wherein the tooth-wound coils or chorded coils of the winding system extend from the first flange to the second flange.

7 . The dynamo-electric machine as claimed in claim 6 wherein the winding cap comprises ribbing arranged between the first flange and the second flange.

8 . The dynamo-electric machine as claimed in claim 7 wherein the ribbing extends from the first flange to the second flange.

9 . The dynamo-electric machine as claimed in claim 1 wherein the opening extends farther from the first side than the recess extends from the first side.

10 . The dynamo-electric machine as claimed in claim 1 wherein the cutout is positioned opposite the recess of the first flange.
