Patent ID: 7579740

Claim:
An automotive alternator voltage control apparatus comprising: an annular slinger; a brush holder which extends radially from an outer peripheral wall surface of the slinger comprising: a brush insertion aperture open at an inner peripheral wall surface of the slinger, and first and second circumferential surfaces; positive and negative electrode brushes inserted into the brush insertion aperture to line up in an axial direction of the slinger and be movable in a radial direction of the slinger; a voltage regulator disposed proximate to and extending radially from the slinger and comprising: an integrated circuit (IC) which comprises a circuit to control an automotive alternator output voltage; a surge absorber disposed proximate to and extending radially from the voltage regulator that absorbs surges arising due to the output voltage control by the voltage regulator; and a connector disposed proximate to and extending radially from the surge absorber to provide an input and an output from and to an external device, wherein the voltage regulator, surge absorber and connector are aligned proximate the first circumferential surface of the brush holder and distal the second circumferential surface of the brush holder.
