Adaptable rotating rectifier and suppression resistor assembly for two-pole, wound rotor of dynamoelectric machine
First Claim
1. An adaptable rotating rectifier and suppression resistor assembly for a rotor of a dynamoelectric machine, said assembly comprising:
- a tubular housing having an axially extending internal cavity without an integrally formed end at its two opposite ends;
a plurality of bus bars arranged in fixed spaced relation in a radially outer portion of said internal cavity so as to extend axially along said internal cavity;
a plurality of diodes and a suppression resistor placed in line along said axis of said internal cavity with radially outwardly extending spring contact plates electrically connecting said diodes and suppression resistor with said bus bars;
an end cap at a first of said two opposite ends of said internal cavity of said tubular housing, said end cap being rotatably connected to said tubular housing and having electrical terminals extending therethrough, respective ones of said bus bars being connected to said terminals for making electrical connections with said assembly and for rotationally positioning and constraining said end cap with respect to said tubular housing, said end cap and said tubular housing being rotatably connected by a twist lock connection therebetween, said electrical connections of said bus bars and terminals of said end cap rotationally positioned with respect to said end cap so that said end cap is constrained in a locked position of said twist lock connection for securing said end cap on said tubular housing; and
a retainer connected to said tubular housing at a second end thereof of said two opposite ends.

Abstract
An adaptable rotating rectifier and suppression resistor assembly is designed to fit and mate with state-of-the-art, two-pole generators with maximum flexibility to accept a variety of known possible diode configurations and a relatively large suppression resistor in a cost effective manner. A tubular housing of the assembly has an axially extending internal cavity with a plurality of bus bars arranged in fixed, spaced relation in a radially outer portion of the internal cavity so as to extend axially along the internal cavity. A plurality of diodes of any one of at least three significantly different configuration diodes and a suppression resistor are arranged in line along the axis of the internal cavity with radially outwardly extending spring contact plates electrically connecting the diodes and suppression resistor with the bus bars. A desired preload force is provided on these components between an end cap at one end of the housing and a retainer at the other. The end cap is rotationally indexed and constrained with respect to the housing by connections of terminals in the end cap with bus bars.
