  • Patent number: 6956743
    Abstract: An electronic component formed as a regulator for generators in motor vehicles has an IC block arranged on a cooling body, connectors provided with conductors, bond wire connectors connecting the IC block with the conductors, the conductors being provided at first ends which face the IC block with a first bond pad, forming a limited free space behind the first bond pad as seen from the IC block for insertion and withdrawal of a bond tool, the conductors of the plug connectors being each provided with a second bond pad located behind the limited free space at a distance from the first bond pad, for further bond wire connections of at least one selectively useable electronic component.

  • Patent number: 6897583
    Abstract: In an electrical machine, in particular a generator for a motor vehicle, having a housing (2), a rotor (6), supported rotatably in the housing (2) about a pivot axis (5), at least one fan wheel (20), connected to the rotor (6), for generating a cooling air flow (22, 22?, 22?) from at least one intake opening (37; 37?; 37?) disposed in the housing (2) to at least one outlet opening (24) disposed in the housing (2), and at least one regulator chip (31), disposed on a chip holder (30), for regulating the current generation, it is provided that the chip holder (30) is disposed such that it is bathed at least in part directly by the cooling air flow (22, 22?, 22?). As a result of this arrangement, it is attained that a very high heat transfer coefficient is present, because of the high flow speed of the cooling air flow (22, 22?, 22?).
