External rotor-type motor

Abstract

Abstract 1. An outer rotor motor comprising an insulating end plate (2) arranged between the stator plates and the winding head of the stator winding, with an axial collar (21) which embraces a shaft end or inner tube inserted into the bore in the stator plates, and with a circuit board (3) arranged between a winding head (8) and the opposite bearing plate (5), with conductor paths (12-16) attached thereto, and in particular printed thereupon, and which are connected to the winding ends of the stator winding and to an outer motor connection cable (9), characterized in that the circuit board (3) with the outwards directed motor connection cable (9) is pre-mounted on the bearing plate (5) and is provided with fixed contact bushes (B1; B2; B3) which, during the assembly connection between bearing plate (5) and stator plates (10) can be automatically plugged onto the free ends of corresponding contact pins (K1; K2; K3) which are connected to the ends of the stator winding and which are held in axial openings in the end of the collar apart from a free end which projects from the end of the opening.
