Abstract: An improved power supply unit for a vehicle electrical system of a motor vehicle, which has an a.c. generator, that provides a phase signal, having an excitation coil, a field regulator assigned to the excitation coil and a rectifier having rectifier elements for the rectification of the generator voltage supplied by the a.c. generator. The field regulator has a voltage detection range for the evaluation of the phase signal having a minimum value and a maximum value, the maximum value being adjusted to the nominal voltage of a power supply unit of the motor vehicle.

Abstract: A support device and method for fixing a bearing on a bearing shield of a housing of an electric machine. Rotatably mounted in the support device is a rotor with a shaft. The support device is substantially flat and comprises a plurality of fastening openings that are grouped about a central opening. The support device comprises at least one design break point that acts to provide a local limit to the excess stress in the material of the support device.

Abstract: The invention relates to a support device (60) for fixing a bearing (28) on a bearing shield (13.1, 13.2) of a housing (13) of an electric machine (10). Rotatably mounted in the support device is a rotor (20) with a shaft (27). The support device (60) is substantially flat and comprises a plurality of fastening openings (62) that are grouped about a central opening (64). The support device (60) comprises at least one design break point (66, 68; 72, 74; 76, 78; 92) that acts to provide a local limit to the excess stresses in the material of the support device (60).
