  • Rotating rectifier assembly
    Patent number: 5124603
    Abstract: A rotatable rectifier assembly has four rectifiers each comprising a group of bead type diodes mounted between axially spaced electrical conductors, the conductors being pre-loaded together to enable the diode connections to better withstand centrifugal forces. The assembly includes a spacing material to take up manufacturing tolerances and thereby ensure that each of the diode groups takes a substantially equal proportion of the applied pre-load.
