Abstract
An active part of an electric machine includes a plurality of coils, each having a sub-conductor. The coils are formed by windings of the sub-conductors thereof. The windings of a coil each have a predetermined winding length. In addition, the active part has a carrier part, in the grooves of which, the coils are arranged. The coils have a winding head region which projects from an end surface of the carrier part. The coils are also arranged in the form of a tiered winding. At least one of the coils has a V-shaped cross-section in the winding head region, as a result of an arrangement of its sub-conductor

9. An active part of an electric machine, comprising:
-
a plurality of coils arranged in the form of a tiered winding, each coil having a sub-conductor and formed by windings of the sub-conductor, with the windings of a corresponding one of the coils having a pre-determined winding length; and a carrier part having grooves for receiving the coils such that a winding overhang region of the coils projects at an end face of the carrier part, with at least one of the coils configured in a two-part form to define in the winding overhang region a first coil part and a second coil part which are arranged to form a V shape in cross-section and are insulated independently from each other, wherein the coils are distanced from each other by a pre-defined minimum spacing such that three of the coils in the tiered winding have in relation to the end face of the carrier part an inclination of 0°
, 45° and
90°
, respectively, with a tolerance range between −
25° and

, with the one of the three coils at the 45°
inclination having a V shape in cross-section. - View Dependent Claims (10, 11, 12, 13, 14)

21. A method for producing an active part, comprising:
-
arranging coils in grooves of a carrier part at a pre-defined minimum spacing from each other; forming each of the coils with a winding overhang region such as to project at an end face of the carrier part; arranging the coils in the form of a tiered winding such that three of the coils are arranged in the tiered winding with an inclination of 0°
, 45° and
90°
in relation to the end face of the carrier part, respectively, with a tolerance range between −
25° and
+25°
;dividing at least one of the coils into a first coil part and into a second coil part such that the first and second coil parts form in the winding overhang region legs of a V shape in cross-section; and insulating the first and second coil parts insulated independently of each other by a tape insulation. - View Dependent Claims (22)
