Three phase alternator with common neutral leads

摘要

A stator of a vehicle mounted alternator having a rotor and a rectifier includes an armature core formed in an inner periphery thereof with a plurality of slots and three-phase armature coils wound in respective slots, coil lead terminals and a neutral lead terminal of the armature coils for each phase being arranged in a limited area so that connections thereof to said rectifier of the alternator are facilitated. The neutral leads for three phases are derived directly at a position between the coil leads, and at least one metal binder for bundling and electrically connecting the neutral leads together at the point is provided, from which a neutral lead terminal to be connected to the rectifier is derived.
