  • Patent number: 6333579
    Abstract: In a stator for an outer rotor-type multi-pole generator, in which coils of an identical type but different from a coil wound around a particular one of cylindrical portions integrally included in a bobbin to cover a plurality of salient poles of a stator core, are wound around a pair of the cylindrical portions adjoining and located on opposite sides of the particular cylindrical portion, a recess concaved inwards in a radial direction of a core base is provided in a guide projection at a location corresponding to the particular one of the cylindrical portions, and a crossover wire is disposed in the recess. Thus, the particular cylindrical portion and the crossover wire can be insulated from each other to ensure a stable insulating property, while avoiding an increase in operating steps.

  • Patent number: 6091172
    Abstract: An outer rotor-type multi-pole generator includes a plurality of coils wound around a large number of protruding poles provided around an outer periphery of a stator core through a bobbin, and terminal members fitted into fitting tube portions integrally provided on the bobbin to pass through the stator core over opposite ends of the stator core. Each of the coils is connected to one end of the terminal member. Each of the terminal members includes a flat plate-shaped base portion fitted into the fitting tube portion and a clamping plate portion protruding sideways from one end of the base portion. The end of the coil is connected to the one end of the terminal member by fusing with the clamping plate portion being folded in such a manner that the end of the coil is clamped between the clamping plate portion and one end of the base portion. Thus, the operation for connecting the coils to the terminal members is facilitated, and the number of steps of the connecting operation is reduced.
