Abstract:
A stator for an outer rotor multi-pole generator, comprising a stator core including a plurality of salient poles projectingly mounted at equal distances from one another on an outer periphery of a core base formed into a ring shape, and a bobbin made of a synthetic resin, wherein said bobbin is integrally provided with a main bobbin portion covering at least the outer periphery of said core base, a plurality of cylindrical portions protruding from said main bobbin portion so as to cover said salient poles excluding tip ends of the salient poles, and a guide projection which protrudes in a cylindrical shape from one end surface of said main bobbin portion, said stator core and said bobbin being coupled by molding to each other, and a plurality of first coils identical to one another but different from a second coil wound around a particular one of said cylindrical portions, each one of a pair of the first coils is wound around a respective one of a pair of the cylindrical portions adjoining and located on opposite sides of said particular one of the cylindrical portions, a crossover wire connecting said pair of identical first coils being disposed along a portion of an outer periphery of said guide projection, and wherein said guide projection is partially depressed radially inwardly to define a recess between the outer periphery of the guide projection and radially inner ends of said first and second coils, said crossover wire being disposed in said recess.
