Abstract
A feeder arrangement of an AC generator includes slip rings, brushes, a brush holder in which an air chamber is formed, and a slip-ring cover. A partition member is disposed in the air chamber to divide the air chamber to form a U-shaped air passage having an air passage connecting to the outside of the slip-ring cover and an air outlet passage connecting to the inside of the slip-ring cover, so that air flows through the U-shaped air passage to remove worn powder of the brushes from the slip rings.
