  • Publication number: 20040027014
    Abstract: In an electronically commutated direct-current motor having a stator (14) with a multi-phase stator winding (15) and a housing (11) receiving the stator (14), having a commutation device (21), disposed in the housing (11) for consistent connection of the winding phases to a direct voltage from the electrical system, which has a plurality of semiconductor switches (22) and an electronic control unit (26), received by a printed circuit board (24), for triggering the semiconductor switches (22), and having a connection plug (13) for delivering the direct voltage from the electrical system, in order to provide a more-robust embodiment of the commutation device (21), all the electronic components of the commutation device (21) that carry power currents, such as the connection plug (13), semiconductor switches (22), electrolyte capacitor (25), and so forth, are contacted on a stamped grid (23), with which the electrical connection with the stator winding (15) and the printed circuit board (24) is established.
