Abstract: The invention relates to a starter generator for an internal combustion engine having a rotor and a stator, whose structural elements substantially comprise stacked, joined-together metal sheets.

Abstract: In a drive train assembly for a motor vehicle, which includes successively arranged an internal combustion engine, a starter clutch, an electrical machine a drive clutch, and an automatic transmission, preferably an automated manual transmission, a common double clutch positioner is assigned to the two clutches, which enables a selective setting of the applicable status (open or closed) of the clutches by assumption of a corresponding switching position.

Abstract: The device according to the invention offers the advantage that by means of at least two drive positions and a neutral position of a planetary gear as a drive transmission for an electric machine, this electric machine can be used both as a starter for starting the internal combustion engine and as a generator for supplying power to an electrical system of the motor vehicle. The disposition of the electric machine connected in series with the planetary gear, for example in the drivetrain of the motor vehicle between a coupling and a manually shifted transmission preferably on a transmission input shaft, in particular has the advantage that the electric machine can remain in constant engagement without expensive devices for meshing and demeshing a conventional starter, and a control of the planetary gear based on fixed parameters can be carried out simply by means of the motor control.

Abstract: In a starter-generator for a motor vehicle, having an electrical machine that can be coupled selectively to an internal combustion engine and/or a transmission of the motor vehicle, the electrical machine (9, 12) is accommodated in a shallow cylindrical housing (5), which on axial opposed face ends is provided with means (28) for securing it to the engine or to a housing of the transmission. This makes it possible to combine the engine, the starter-generator, and the transmission into a compact, linear group.

Abstract: An electrical machine for starting an internal combustion engine and/or for voltage supply of a vehicle electrical system of a motor vehicle has a housing, a stator mounted on the housing, a claw pole rotor system, a separable operative connection with an internal combustion engine, and separate circulations with different cooling media for the stator and the rotor.
