  • Reduced length rotating rectifier assembly
    Patent number: 5003209
    Abstract: The disclosed rotating rectifier assembly (12) has a reduced axial length thereby achieving the goal of reducing the overall axial length of a brushless generator (10) which includes a rectifier assembly disposed along its axis (26) for developing DC output power from three phase AC power supplied by a three phase rotor armature (14) also contained within the generator (10). A typical rotating rectifier assembly is comprised of plates and diodes arranged in a stack clamped axially along the axis of rotation with a diode sandwiched between each adjacent pair of plates. The reduction of the axial length of the rectifier (12) is achieved by positioning a stack (67) of diodes (19) and plates (52 through 64) perpendicular to the axis of rotation (26) while providing the necessary electrical conductors to define a rectifier circuit.
