Abstract
The invention relates to a rotor, in particular for a current-excited synchronous machine, comprising a rotor main body which has a plurality of rotor teeth, the rotor teeth being wound with a conductor material in order to form a winding, the conductor material having conductor ends which, in order to produce an electrical connection, are pressed axially against a stop via a contact element, and the contact element or the stop being designed to electrically connect, in the circumferential direction, at least two conductor ends.
Claims7
A rotor comprising:
- a main rotor body, which comprises a plurality of rotor teeth;
- and
- a conductor material wound around the rotor teeth to form a winding,
- wherein the conductor material has conductor ends, which are pressed axially against a stop by a contact element to establish an electrically conductive connection,
- wherein the contact element or the stop is configured to electrically conductively connect at least two of the conductor ends in a circumferential direction,
- wherein the contact element or the stop comprises a conductor element, which makes it possible to provide the electrically conductive connection between the at least two of the conductor ends in the circumferential direction,
- wherein the contact element or the stop comprises a plurality of pockets which have a ray-like arrangement and are configured to arrange and position the conductor ends, and
- wherein an intermediate element, which is configured to deform during a pressing operation for connection to the conductor element, is arranged in at least one of the pockets.
A method for producing a rotor, the method comprising:
- providing a rotor body and a winding conductor material around the rotor body to form a winding, wherein the winding has conductor ends;
- pressing the conductor ends against a stop via a contact element;
- and
- establishing an electrically conductive connection between at least two of the conductor ends via the contact element or the stop,
- wherein the contact element or the stop comprises a conductor element, which makes it possible to provide the electrically conductive connection between the at least two of the conductor ends in the circumferential direction,
- wherein the contact element or the stop comprises a plurality of pockets which have a ray-like arrangement and are configured to arrange and position the conductor ends, and
- wherein an intermediate element, which is configured to deform during a pressing operation for connection to the conductor element, is arranged in at least one of the pockets.
