Stator and method for producing a stator for an electrical machine, comprising a stator main body () which has radial stator teeth () for receiving coils () of an electrical winding and, on an end side of the stator main body (), has an insulating lamination () with receiving pockets () for insulation-displacement terminal elements (), wherein the coils () are wound by means of a winding wire which is inserted into the receiving pockets (), wherein an interconnection plate () has annular conductors () on which in each case a plurality of insulation-displacement terminal elements () are arranged, which insulation-displacement terminal elements axially engage into the receiving pockets () in order to make electrical contact with the winding wire, wherein the interconnection plate () is manufactured from plastic and has annular grooves () which are open axially at the bottom and into which the annular conductors () are inserted.

Stator for an electrical machine, an electrical machine and method for producing a stator of this kind

The invention relates to a method () for electrically contact-connecting a winding () of an electrical machine () to a printed circuit board (), wherein the electrical machine () has an armature () with a large number of teeth (), wherein at least one winding (), which is formed by an electrical conductor (), is formed on one of the teeth (). The method comprises the following steps: routing () the conductor ends () of the electrical conductor () out of the armature () in the axial direction of the electrical machine (), shortening () the conductor ends () to the same length, routing () the conductor ends () through in each case one passage opening () in a centring element (), wherein the centring element () has a centring means () which centres and orients in parallel the routed-through conductor ends (), wherein the routed-through conductor ends () emerge from the centring element (), routing () the conductor ends () through in each case one passage opening () in a sealing element (), wherein the routed-through conductor ends () emerge from the sealing element (), inserting () the centring means () into in each case one passage opening () in a sealing element (), arranging () the sealing element () at least partially within a passage opening () in a housing element (), and electrically contact-connecting () the conductor ends () to the printed circuit board ().
