Abstract:
1. An electronic package for an electrical machine comprising: a rotor having an axis; a slip ring end (SRE) frame, having a first face and a second face, defining one end of a housing supporting the rotor therein so as to be rotatable; 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 located adjacent 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, having a first side and a second side, with a heat sink on at least one of the first side and the second side, the regulator being 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, wherein each of the regulator first and second sides are perpendicular to each of the SRE frame first and second faces and are parallel to the axis of the rotor; and a plurality of carbon brushes within the brush holder wherein the second side of the regulator mates to the brush holder and the second side of the regulator is parallel to a direction of brush travel.
