An electric machine designed as a starter, generator, or starter-generator for a motor vehicle and presenting a housing, wherein said housing comprises a winding with coils or coil groups including connector heads. It comprises power electronics units with power switch components distributed along the perimeter of the housing, as well as conductor rails connected with power electronics units, and coil exit rails going from a power electronics unit to an associated coil or coil group. Said power electronics units are arranged on the face of the housing in a clearance created by the connector heads, which are located radially outside or inside the connector heads. Said power switch components comprise a contact area and are arranged directly&#x2014;without inserted electric insulation&#x2014;on one of the power loops or a coil exit rail.

Method for cleaning vehicle windows

To make holes in ceramic green sheets that are needed to create feedthroughs, it is proposed to make the holes by using a gas that is under a higher pressure than atmospheric pressure and that is expelled in a pulsed manner from a pressure vessel and thereby acts on a principal surface of a ceramic green sheet, at at least one location at which a hole is to be made, in such a way that material is shot out of the ceramic green sheet at that location. This eliminates the disadvantages associated with the use of punches to punch holes.

An electronic power circuit includes several power modules ( ) and is especially for controlling an electrical machine. Each power module ( ) includes a plate-shaped integrated electronic circuit arrangement ( ) having several electrical terminals. A perpendicular bent-over electrically conducting side leg ( ) is arranged on each of two opposite-lying sides of the plate-shaped circuit arrangement ( ). The side leg ( ) forms an electrical contact and, in this way, the power module ( ) has a U-shaped cross section. Each side leg ( ) is provided with connecting elements via which two or several power modules ( ) can be electrically and mechanically fixedly connected to each other while forming a mutual spacing between the plate-shaped circuit arrangement ( ) via the side legs ( ) for forming the electronic power circuit.

Disclosed in a power semiconductor module which includes a stack of carrier substrates, disposed one above the other in multiple layers and provided with at least one conductor track on at least one main surface, in which at least one electronic semiconductor component is disposed between two adjacent carrier substrates of the stack and is contacted electrically and heat-conductively to at least one conductor track of a carrier substrate disposed in the stack above the semiconductor component and to at least one further conductor track of a carrier substrate disposed in the stack below the semiconductor component. To both improve heat output and provide a compact design, the two outer carrier substrates of the stack are embodied as one upper and one lower housing wall of a closed housing part surrounding the at least one semiconductor component, and the interstices between the stacked carrier substrates are tightly closed by an encompassing wall secured to the carrier substrates.
