Abstract
A vehicle AC generator has a stator winding formed of series-connected U-shaped conductor segments, with a plurality of connection portions, each formed of a pair of connected tip portions of respective conductor segments, protruding axially at one end of the stator core, with a flow of cooling air being impelled outward from the rotor along a flow direction that deviates from a radial direction, to pass between the connection portions. Each connection portion is oriented along a direction that deviates from a radial direction, to reduce air flow resistance and reduce audible noise caused by the air flow.
Claims7
An AC generator for installation in a vehicle, comprising a rotor that is driven for rotation, a stator having a stator iron core fixedly disposed opposing the stator, a stator winding disposed in said stator iron core, and a frame which supports said rotor and stator, said stator winding comprising a plurality of conductor segments each basically formed in a U-shaped configuration having two linear portions that are connected by a turn portion and that extend to respective tip portions, with pairs of said tip portions of respective conductor segments being connected together;
- wherein each said pair of connected tip portions are oriented along a direction that is inclined by a specific angular amount with respect to a radial direction of said stator.
