Adaptable rotating rectifier and suppression resistor assembly for two-pole, wound rotor of dynamoelectric machine

DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS Referring now to the drawings, an adaptable rotating rectifier and suppression resistor assembly 10 according to the invention is for a rotor of a dynamoelectric machine, particularly a two-pole generator of an aircraft integrated drive generator.
The assembly of the embodiment of FIGS.
1-6 comprises a tubular housing 11 having an internal cavity 12 extending along the longitudinal axis A--A as shown in FIG.
5.
Six bus bars 13 are arranged in fixed, equally spaced relation in axially extending grooves 14 in a radially outer portion of the internal cavity so as to extend axially along the cavity.
Three of these bus bars are for electrical connection with terminals 15 in an end cap 16 of the assembly for connection with the exciter.
A fourth bus bar is connected with a counterweight terminal 17 in the end cap.
The other two bus bars extend out through the opposite end of the assembly for connection with the main field, see FIGS.
2 and 4.
A plurality of diodes 18 and a suppression resistor 19 are placed in line along the axis A--A of the internal cavity with radially outwardly extending spring contact plates 20 electrically connecting the diodes and suppression resistor with the bus bars.
An end cap 16 is positioned at one end of the internal cavity of the tubular housing.
It is rotatably connected to the tubular housing by twist lock connection 30, see FIGS.
5 and 6 formed by tabs in the end cap and cooperating grooves in the tubular housing.
The electrical terminals 15 extend axially through the end cap 16.
Four of the bus bars are connected to respective ones of the exciter connection terminals after the end cap has been rotatably connected with the tubular housing in the locked position of the twist lock connection by inserting the end cap in the housing cavity and relatively rotating the end cap and housing to a position for connection of the four bus bars to the respective terminals.
This position corresponds to a locked position of the twist lock connection, e
