Abstract
The invention relates to a circuit configuration for connecting the stator windings of a brushless, electronically commutated motor, especially as a drive motor for an automobile fan drive. The configuration comprises a circuit board (63) with conducting paths, each of which is connected to the wire leads of the winding coils of each phase winding and one of which is connected to the ends of winding coils of all of the phase windings. This electronically commutated motor simplifies the interconnection of the stator windings in that the circuit board (63) includes an annular disk-shaped support plate (65) which, together with the stator assembly, is attached by a hub (67) to a bearing support pipe on the motor flange. The conducting paths are made of stamped conductor rails (73, 75, 77, 79) which are fixed on the support plate (65), concentrically to the hub (67).
