Active part of an electrical machine having inclined coils in the winding head area
First Claim
1. An active part of an electrical machine, comprising:
- a carrier having a front face and defining a main axis;
a winding head area; and
a plurality of coils arranged on the carrier and having each a plurality of sub-conductors, said coils projecting out from the front face of the carrier in an arced shape into the winding head area and being connected to one another, each of the coils having a coil arc in the winding head area and defining a center line which essentially runs in a plane in the coil arc, with the sub-conductors of the coil running parallel to the plane in the coil arc and configured to form sub-conductor arcs having vertices that define a line of inclination which extends at an angle to the front face of the carrier and at an angle to the main axis of the carrier,wherein three adjacent ones of the coils define planes which are arranged at angles of 0°
, 45° and
90°
in relation to the front face of the carrier.

Abstract
An active part of an electrical machine has a carrier, a plurality of coils which are arranged on the carrier and which each include a plurality of sub-conductors and a winding head area, in which the coils project out of the carrier in a curved shape, respectively and are connected to one another. At least one of the plurality of coils has a coil arc in the winding head area, and the center line of the coil runs in one plane in the coil arc. The sub-conductors of one coil run parallel to the plane in the coil arc of the coil and themselves in each case form sub-conductor arcs. The vertices of the sub-conductor arcs of the coil form a line of inclination which runs at an angle to the plane.
