ROTATING RECTIFIER ASSEMBLY FOR BRUSHLESS EXCITERS

摘要

Brushless excitation systems for alternating current generators include an alternating current exciter and a rotating rectifier assembly. In such a system, the rectifier diodes of the rectifier assembly are mounted on the rim of a wheel which rotates with the exciter armature member, and the leads from the exciter winding extend along the shaft and through openings in the wheel for connection to the diodes. Supporting means are provided for the leads consisting of an elastic tubular member such as an aluminum sleeve, which extends axially from the wheel and encloses the leads. The leads are supported radially against the inner surface of the tubular member which has sufficient elasticity to permit limited radial deflection of the leads to follow the wheel when it expands radially in operation.
