In an electronically commutated DC motor having a stator unit () and a rotor unit () which is in the form of an external rotor, and having stationary sintered bearings (), the invention proposes that the rotor unit () is conductively connected to the shaft () in order to connect a conductive shielding, which is formed on the rotor unit (), to a defined electrical potential, and that the sintered bearing () is conductively connected to the potential, so that the shielding of the rotor unit () is capacitively coupled to the potential by means of the electrically insulating, oil-filled bearing gap which is arranged between the shaft () and the sintered bearing (). Therefore, a sliding contact is not required.

Electronically commutated DC motor with shielding

The invention relates to a climate control system for the interior of a motor vehicle, having a blower regulator, heating control unit or brushless blower motor, as well as function components such as operating elements, sensors, clocking valves and adjusting drive mechanisms, which are connected to one another and to the vehicle battery via connecting lines and to which the information required to operate the blower regulator, heating control unit or brushless blower motor are transmitted. The cabling and the control/regulation are minimized and simplified by providing that the blower regulator, the heating control unit, or the brushless blower motor is combined with the function components to make a pre-wired climate control unit, to which the supply voltage of the vehicle battery; that the blower regulator, the heating control unit, or the brushless blower motor is designed in bus-capable fashion with a microcomputer, which communicates via a bus interface with a climate control operating device supplied by the supply voltage; and that the information required for operating the climate control apparatus can be transmitted between the climate control operating device and microcomputer as part of a bus protocol on the bus interface.

A diagnostic device and a diagnostic method for use with a bus system that includes stations interconnected over a bus, one station of which is set up as the master station and the other stations being slave stations. A diagnosis operation is performed which allows differentiated fault information to be obtained with regard to individual outputs of the stations, where the expenditure for the diagnostic device is low. The diagnosis is achieved by providing a diagnostic device only in the master station, by storing voltage and/or current information on at least one output of at least one slave station to be diagnosed in the diagnostic device, and by performing the diagnosis of the outputs under preselected or preselectable conditions on the basis of a program stored in the master station.
