Abstract

An electrical power tool has an electronically commutated drive motor, preferably a direct current motor. The motor includes a stator core equipped with an insulating body, on which core a motor winding is embodied. Also included in the motor is at least one electrically conductive connector element for electrical connection of the motor winding, the connector element being disposed on the insulating body. The connector element has a fastening segment, and a receptacle for reception of the fastening segment is provided on the insulating body. The fastening segment and the receptacle have complementary geometrical shapes that prevent self-actuated detachment of the fastening segment disposed in the receptacle.
