Electronic package for electrical machine

An electronic package for an electrical machine comprising:

• a slip ring end (SRE) frame defining one end of a housing configured for mounting a rotor therein so as to be rotatable, the SRE frame having a cast wall along an inside diameter;
• a plurality of slip rings positioned on a shaft of the rotor;
• a plurality of negative diodes dispersed in an angular fashion in the SRE frame acting as a negative heat sink;
• a plurality of positive diodes mounted on a separate electrically conductive plate, having stamped fins on an outer diameter, located above a location of the plurality of negative diodes, the plate being configured as a positive heat sink having corresponding holes such that leads extending from each negative diode protrude directly therethrough and openings formed in the positive heat sink engage a body of each positive diode;
• a non-conductive separator fitted over a series of bosses that space the positive heat sink above a top surface defining the negative heat sink, the separator configured to electrically insulate the positive heat sink and negative heat sink from one another;
• a terminal assembly configured to make appropriate electrical connections between the positive and negative diodes, stator phase leads, and a regulator;
• the regulator is operably fastened to the SRE frame at a plurality of locations, the regulator electrically connects to the positive heat sink, a stator phase terminal extending from the terminal assembly, SRE frame, and a brush holder assembly, the regulator having a heat sink on a first side parallel to an axis of the shaft;
• the brush holder assembly further comprising a plurality of brushes wherein the cast wall of the SRE frame surrounds the plurality of slip rings and the plurality of brushes;
• and
• the regulator having a second side the second side being parallel to the first side and parallel to a direction of brush travel, the brush holder being mounted to one of the first side and the second side.
