摘要： A pump includes an electric motor with a rotor mounted rotatably about an axis of rotation and circumferentially surrounding a stator that includes a stator core and coils wound on the stator core. The windings are defined by a winding wire with winding wire end sections electrically contacted directly with a printed circuit board at an end surface through insulation displacement contacts each including at least one opening for insertion of a winding wire end section, the at least one opening being a slot extending parallel or substantially parallel to a surface of the printed circuit board.

摘要： An electric motor includes a rotor and a stator including a stator core and coils. The coils are defined by a winding wire including winding wire ends electrically contacted with a printed circuit board at an end surface through connectors. The connectors each include at least two insulation displacement contacts receiving a winding wire end of a stator winding. Each connector includes a single electrical connection to the printed circuit board. The connector includes a base body with an underside in contact with the printed circuit board. Each of the at least two insulation displacement contacts includes a clamping slot perpendicular to the underside of the base body. The clamping slots are defined by spaced legs extending from the base body, at least two of the spaced legs being resilient.
