Abstract
A rotor for an electric machine includes a rotor main part which has at least one pole core, at least one winding device which is received on the at least one pole core, and at least one contact device which is rotationally fixed to the rotor main part and which is coupled to the at least one winding device to conduct a current. The at least one winding device includes at least one winding that is plugged onto the at least one pole core and has two winding wire ends, at least one winding wire end of which is coupled to the at least one contact device to conduct a current via at least one plug connection.
Claims10
A rotor for an electric machine, the rotor comprising:
- a rotor body which has at least one pole core,
- at least one winding device which is mounted on the at least one pole core, and
- at least one contact device which is non-rotatably connected to a rotor base body and is conductively coupled to the at least one winding device, wherein:
- the at least one winding device contains at least one winding which is attached to the at least one pole core and has two winding wire ends, of which at least one winding wire end is coupled in a conductive manner via at least one plug-in connection to the at least one contact device, and
- the at least one contact device contains at least one spring element, by way of which the at least one winding wire end is coupled to the at least one contact device with formation of the plug-in connection.
