DETAILED DESCRIPTION The above discussed and other drawbacks and deficiencies are overcome or alleviated by an electronic package for an electrical machine preferably a rotary current generator includes a slip ring end (SRE) frame defining one end of a housing configured for mounting a 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 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 to 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 assembly; and the regulator assembly is operably fastened to the SRE frame at a plurality of locations, the regulator assembly electrically connects to the positive heat sink, a stator phase terminal extending from the terminal assembly, SRE frame, and a brush holder assembly; wherein waste heat from the positive and negative heats sinks is to be carried off via vents configured in each and radially outwardly across surfaces defining each.
In another embodiment, an output connection for an electrical machine, preferably a rotary current generator is disclosed.
The output connection includes a B+ stud defined by a head at one end and threaded on the other end, the B+ stud protrudes through a positive heat sink anchored by the head resting against a surface defining the heat sink; a metallic spacer disposed over the B+ stud such that when an external battery cable is operably attached to the B+ stud, the B+ stud is in tension and the spacer is in compression when an external nut is fastened on the B+ stud; and knurling on at least one of the B+ stud and an inside diameter surface of the spacer such that when the metallic spacer is disposed on the B+ stud, the stud and spacer are in press-fit engagement
