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.

摘要： First, a rectifier assembly is assembled from a negative heat sink assembly, a positive heat sink assembly, a circuit board assembly, and a guide. Subsequently, stator coil connecting terminals of the rectifier assembly are chucked by using a grounded chucking jig. Then, under this condition, powder coating charged with a plus polarity is sprayed to this rectifier assembly, and thus the sprayed powder coating is absorbed onto a surface of an exposed metal of the rectifier assembly by the electrostatic force. Thereafter, a heating process operation is carried out to heat/harden this powder coating, so that the insulating film is formed on the surface of the exposed metal of the rectifier assembly.
