Abstract: 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—without inserted electric insulation—on one of the power loops or a coil exit rail.

Abstract: The invention concerns a winding for a post or an armature of an electric machine with a post or armature (32) with slots (34) composed at least in part of L-shaped structural parts (1, 2, 3).

Moreover, the invention concerns a winding with several interlaced coils (50, 52, 50?, 52?, 50?, 52?) whereby the connecting lines (6) of interlaced coils (50, 52, 52?, 50?, 52?) are staggered and therefore arranged in layers. The invention furthermore concerns a winding with connecting lines (6) flatter than the slot bars (8), styled as a fractional pitched polyphase winding with two slots per pole and branch.

Abstract: Systems and methods are disclosed to store electrical energy in, for example, a vehicle. In an example system, a storage module is provided including one or more capacitors, a sensor to measure the temperature of the capacitor(s), and a control device that controls the voltage at the capacitor(s) so that the maximum voltage at the storage module and/or the individual capacitor(s) increases as the temperature decreases. The aging of the capacitor(s) and in particular electrochemical capacitors strongly depends on the temperature in addition to the operating voltage. Controlling the capacitor voltage based on temperature can, therefore, substantially reduce the aging of the capacitor(s).

In the event of a disturbance of the electromagnetic valve actuation, the valve mechanism corresponding to the particular control device (2) can be displaced at least so far that the valve plate (8) has left the collision position thereby reliably avoiding a collision between piston base and valve plate (8). The control device can be used in a reciprocating engine, a piston compressor or a machine having the same operating principle.
