The invention relates to a method (100) for electrically contact-connecting a winding (40) of an electrical machine (1) to a printed circuit board (92), wherein the electrical machine (1) has an armature (10) with a large number of teeth (20), wherein at least one winding (40), which is formed by an electrical conductor (42), is formed on one of the teeth (20). The method comprises the following steps: routing (110) the conductor ends (45) of the electrical conductor (42) out of the armature (10) in the axial direction of the electrical machine (1), shortening (115) the conductor ends (45) to the same length, routing (120) the conductor ends (45) through in each case one passage opening (67) in a centring element (66), wherein the centring element (66) has a centring means (69) which centres and orients in parallel the routed-through conductor ends (45), wherein the routed-through conductor ends (45) emerge from the centring element (66), routing (125) the conductor ends (45) through in each case one passage opening (73) in a sealing element (72), wherein the routed-through conductor ends (45) emerge from the sealing element (72), inserting (130) the centring means (69) into in each case one passage opening (73) in a sealing element (72), arranging (135) the sealing element (72) at least partially within a passage opening (6) in a housing element (5), and electrically contact-connecting (140) the conductor ends (45) to the printed circuit board (92).
