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.

Power supply unit for a vehicle electrical system of a motor vehicle

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.

Support plate for bearings

The invention relates to an electrical motor (), in particular an alternating current generator, having a housing () that has at least one bearing shield (), having a rectifier device () which has an interconnection unit () that interconnects the current rectifier () to a bridge circuit, characterized in that the interconnection unit () has at least one platform () that is oriented to the bearing shield () and the opening () is separated by at least one brace () which holds a hub (), wherein the opening () has a niche () that is incorporated on the radial outer edge () of the opening and wherein the platform () projects into said niche () and a connection wire () exiting the platform () extends into the opening ().
