Abstract: A stator for an electric machine of a motor vehicle, having an annular yoke, with an inner side directed inwards in the radial direction of the yoke, wherein a plurality of pole teeth are connected by form fit to the yoke on the inner side of the yoke, a stator winding which is formed as a mat and which is arranged between the pole teeth, a first cooling channel through which a cooling medium may flow and which extends in the longitudinal direction of the stator, wherein the first cooling channel is arranged in a recess, and a second cooling channel through which a cooling medium may flow, wherein the second cooling channel is arranged between two adjacent pole teeth between an inner side of the stator winding directed inwards in the radial direction of the stator and a pole shoe of the pole tooth.

Abstract: A method for manufacturing a rotor for an electric machine with a contactless power transmission system, wherein an end winding cover is arranged on one end face of a laminated core of the rotor. The invention provides that a secondary unit (SEC) of the power transmission system is integrated in the end winding cover and, as a result, after the end winding cover has been arranged, the secondary unit (SEC) is held on the rotor indirectly via the end winding cover.

Abstract: A vehicle-side circuit for supplying power in an electrically driven vehicle is provided. The power circuit includes an external AC voltage terminal; at least one DC/AC converter having an AC voltage side; and an electrical machine having a plurality of windings, each of which has a first tapping. The electrical machine is connected to the AC voltage side of the DC/AC converter. A switching device is connected to the plurality of windings and to a signal shaping filter having a plurality of first capacitors. The signal shaping filter is connected between the DC/AC converter and an external AC terminal. The switching device may interconnect the windings within the electrical machine or may connect the first tappings of the plurality of windings within the signal shaping filter to the plurality of first capacitors to form an at least third-order low-pass filter.
