摘要： An automotive alternator reduces invalid magnetic fluxes and uncomfortable noises. In the automotive alternator, the number of slots is one per set of stator coils, per phase, and per pole. The stator coils are disposed such that two sets of three-phase coils have a phase difference from each other, and center-to-center intervals of circumferential gaps of adjoining slot openings are set to be nonuniform. Claw-shaped magnetic poles of the rotor are formed such that at least a narrow tooth of teeth formed between the slots of the opposing stator is positioned to overlap two of the claw-shaped magnetic poles that are adjacent in a direction of rotation of the rotor and have opposite polarities.
