摘要： An electric motor, in particular a radiator fan motor of a motor vehicle, has a rotor which is mounted such that it can rotate in relation to a stator, a motor mount which has an electronics compartment for accommodating a converter electronics system, and an electronics compartment cover. The electronics compartment cover has a peripheral sealing groove into which a peripheral edge of the electronics compartment engages by way of a corresponding sealing web in order to reliably seal off the electronics compartment.

摘要： An electronic assembly contains a circuit board having a current-conducting current path with two mutually spaced-apart current path ends that form an interruption point and a contact clip bridging the interruption point. The contact clip is manufactured without a preload, as a thermal fuse. The contact clip has a multiply bent, open clip loop and a contact limb making contact with both mutually spaced-apart current path ends using solder. The contact clip further has a fixing limb with a limb end seated in a circuit board opening. The limb end of the fixing limb has an oversize relative to a circuit board opening, and a deformation being imparted to the contact clip, with an internal preload being generated.

摘要： A fan wheel has a hub cup and a plurality of blades which are arranged on the hub cup and extend radially outward from an outer wall of the hub cup which is in particular at least substantially cylindrical. Each blade has a leading edge and a trailing edge, wherein for at least one blade, an axial unit depth z*(t) of the blade has an aperiodically wave-like shape. A radiator fan module has a fan wheel of the type described above, and the fan wheel can be used in a motor vehicle.

摘要： A method for operating an electric motor-driven refrigerant compressor of a motor vehicle is provided. A first temperature of a power semiconductor is measured, and a second temperature of the power semiconductor is determined using a theoretical model of the motor-driven refrigerant compressor. A difference between the first temperature and second temperature is determined. A fault is detected if the difference is greater than a first threshold. The invention further relates to a motor-driven refrigerant compressor of a motor vehicle, to the use of a motor-driven refrigerant compressor, and to a motor vehicle comprising a refrigerant circuit.

摘要： A brush system of an electric motor, having a commutator, at least one brush that is guided within a brush duct and is provided with a connection line, and a spring element that exerts a spring force on the brush when the spring element is effectively connected thereto, such that the brush rests against the commutator; the brush duct includes a longitudinal duct slot inside which the connection line extends and which has a constriction that the connection line penetrates when the effective connection between the spring element and the brush is established.

摘要： An electric motor for driving a motor vehicle component, in particular a fan impeller for cooling cooling water, having an electronics unit that includes a lead frame around which injection-molded plastic is provided and which has a current path conducting the motor current, and having two spaced-apart current path ends that form an interruption point bridged by a thermal fuse in the form of a spring-biased contact bridge. The contact bridge is mounted so as to be pivotable about an axis of rotation extending perpendicular to the plane of the interruption point. An abutment contour, against which the contact bridge pivots as a result of the restoring force of a spring element when the thermal fuse is triggered, limits the pivoting range of the contact bridge.

摘要： An apparatus for mounting an electric motor, in particular a fan drive of a heating or air-conditioning system of a motor vehicle, such that vibrations are decoupled, having a number of elastic damping elements which are plug-mounted on the motor, and also comprising a corresponding number of mounting contours, which are associated with said damping elements, in an external housing which at least partially surrounds the motor housing, wherein the respective damping element has a central insertion slot for the corresponding radial lug, and wherein the respective damping element has material spokes, which extend in the manner of a star starting from the insertion slot, so as to form spoke sections which face one another and between which slot regions which are free of material and open at the periphery are formed.

摘要： An electromotive drive being a commutator motor has a motor shaft being rotatably mounted on axially opposite sides in shaft bearings which are each covered by an end plate. A damping system for damping sound is arranged on that bearing side, which is averted from the end plate, of at least one of the shaft bearings. The damping system has an annular sealing disk and an annular sliding disk with an integrated spring element.

摘要： A method produces a rotor which can rotate about a rotation axis, in particular for an electrical machine of a motor vehicle. At least two rotor body elements are each provided with a number of receiving pockets which are made in an axial direction. Magnet bodies are in each case pressed into the receiving pockets in the rotor body elements with an axial press-in direction. The rotor body elements are joined to one another in such a way that the press-in directions of the magnet bodies point away from one another. Additionally, an electrical machine has a rotor which is produced in this manner.
