Abstract
Abstract The assembly includes a plurality of diodes spaced circumferentially about the axis of rotation of the assembly, two spaced apart outer diode mounting members and a plurality of radially inner diode mounting elements. A spacer member is provided which locates the mounting elements in recesses therein. Selected mounting elements are interconnected by linking plates to form a sub-assembly which is received within a housing.
