An electrical machine includes an open-loop or closed-loop control unit and a fluidic actuator, wherein the open-loop or closed-loop control unit is established for open-loop or closed-loop control of the actuator, where the open-loop or closed-loop control unit has a carrier plate cast in a thermally conductive casting compound, and where the open-loop or closed-loop control unit makes contact with a fluid-filled chamber of the actuator in the region of the casting compound such that it becomes possible to dispense with separate cooling devices in the open-loop or closed-loop control unit.

A housing for an electric machine includes a cooling device arranged on the periphery of a support plate, the cooling device contacts a heat-conducting ring connected to the housing, and the support plate as well as components arranged thereon have vibration damping and an electric insulation to provide advantageous structural conditions such that an advantageous cooling effect is achieved, and regions within the cooling device can be provided for fitting elements of the support plate.

An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.

A device for detecting the angle of rotation of a throttle valve operated by an electric motor is disclosed. The valve is rotatably supported on a throttle valve shaft in an intake system of a throttle valve housing, wherein an actuator motor coupled to the throttle valve shaft predefines the throttle valve angular position in a manner controlled by a control unit, and wherein a predetermined value of the throttle valve angular position is predetermined by a manually operated predetermined-value input apparatus and is fed to the control unit. The predetermined-value input apparatus is coupled to a predetermined value sensor shaft, wherein the angular position of the predetermined value sensor shaft corresponds to the manually predefined predetermined value of the throttle valve angular position.

There is described an illumination unit with a planar carrier part having a plurality of light-emitting semiconductor components, in particular high-power light-emitting diodes, arranged on both sides of a main surface. On each side of the carrier part a heat sink is provided in each case. Each of the semiconductor components is connected in an efficient heat-conducting manner to a heat sink provided on an opposite side of the carrier part by way of a heat conducting means that is fed through an opening in the carrier part. At least one reflector is embodied on each heat sink having a reflective surface which concentrates the emitted light from a semiconductor component which is arranged on the side of the carrier part facing this heat sink.

There is described an arrangement for cooling electrical components disposed on a board-shaped mounting substrate, particularly SMD power components on a printed circuit board, wherein at least one heat sink assigned to a component is present which is disposed on the same side as the components and which is connected in a thermally conductive manner to the assigned component by means of a thermally conductive layer implemented on the mounting substrate. The heat sink is implemented as a bent sheet-metal part and is connected to the thermally conductive layer by means of a solder joint, wherein the bent sheet-metal part has at least one heat sink element which extends in a longitudinal direction and said longitudinal direction is oriented obliquely to the plane of the board-shaped substrate.

A tactile braille or graphic display with a laminar display carrier with pattern points which are raised in their tangible positions and are formed by the hemispherical surfaces of feeler balls projecting through openings in the top of the display carrier which feeler balls are selectively brought into their tangible position by adjustment of associated locking balls. A locking armature which can be slid into the underside of the display carrier is provided to adjust each locking ball. This armature can firstly be slid into the locking position by means of a setting armature of a moving setting device and secondly can be released from the locking position by the setting armature after the latter is magnetized. The locking ball is spring-loaded and in the locking position is moved under the feeler ball against the pressure of the spring by the locking armature in order to hold the feeler ball in its tangible position, and preferably a further filling ball serving as a spacer is disposed between the feeler ball and the locking ball. The locking armature is provided with a shoulder which partially grips around the locking ball in the locking position, producing an easily releasable clamping connection, and holds the locking armature in the locking position. The setting armatures for a plurality of pattern points, in particular for the pattern points of a line of shapes, are disposed together with their magnetizing windings on a common setting device which is disposed so as to be displaceable at right angles to the direction of the line of shapes on rails provided at both sides of the display carrier and is adjustable in relation to the display carrier with the aid of eccentrics for the purpose of adjusting the tangible positions of the pattern points of this line of shapes.
