  • Patent number: 9537366
    Abstract: A magnet-type generator 1 has a stator 20 having a stator core 21, bobbins 40, 41 and a coil 60. The stator core has through holes 35A, 35B, 35C passing through the stator core parallel to a rotation axis of the rotor so that lead wires 64A, 64B, 64C for outputting current generated at the magnet-type generator 1, which are corresponding to respective phases, are inserted into the through holes. The lead wires inserted into the through holes are connected with outgoing wires 60a, 60c?, 60b, 60a?, 60c, 60b? of the coil at one side (clamping surface side) of the stator core 21 via a terminal (metal connection terminal) 53 fixed to a substrate portion (plate portion) 48 extending from the bobbin. The terminal is arranged near the through holes.

  • Patent number: 9537365
    Abstract: A magnet-type generator 1 has a stator 20 having a stator core 21 and a coil 60, and fixed on an engine cover. The stator core has an annular base portion 26 and salient pole portions 27 extended in a radial direction from the annular base portion. The coil is wound around winding frame portions formed on the salient pole portions. Lead wires 64A, 64B, 64C are inserted into through holes 35A, 35B, 35C passing through the stator core and connected with outgoing wires of the coil at one side of the stator core. The stator core has an extension portion 33, which is partly enlarged outwards in a radial direction from an outer periphery of the annular base portion and fills a part of a gap 32 between neighboring salient pole portions. The through holes are provided on an area including the extension portion of the stator core.

The stator core has through holes 35A, 35B, 35C passing through the stator core along a rotation axis of the rotor so that lead wires 64A, 64B, 64C for outputting, which are corresponding to respective phases, are inserted into the through holes. The lead wires inserted into the through holes are connected with outgoing wires 60a, 60c?, 60b, 60a?, 60c, 60b? of the coil at one side (clamping surface side) of the stator core 21 via a terminal (metal connection terminal) 53 fixed to a substrate portion (plate portion) 48 extending from the bobbin.

  • Patent number: 7791241
    Abstract: A permanent magnet type three-phase ac generator includes a stator having 3n (n is an integer) teeth and a tree-phase armature winding and a rotor having 4n magnetic poles each of which has a permanent magnet. The three-phase winding includes 3n coils each of which is wound around one of the teeth and connected to form three phase windings, and each coil wound around a first tooth is connected to another coil wound around another tooth that is fourth from the one of the teeth so that vectors of voltage induced in the connected coils can direct in the same direction.

  • Patent number: 7501729
    Abstract: A terminal plate set has multiple terminal plates and fitting legs. Each terminal plate has a transverse bar portion and a longitudinal bar portion. If the fitting legs of the terminal plate set are press-fit into fitting through holes, terminals of the transverse bar portions are positioned on an axial end side of a rotor, and terminals of the longitudinal bar portions are positioned on the other axial end side of the rotor. The length of the transverse bar portions are adjusted so that the terminals of the transverse bar portions are positioned near coil wire leads to be connected with the terminals of the transverse bar portions.

  • Patent number: 7268450
    Abstract: A permanent magnet type generator includes a rotor having 4n (n is a positive integer) permanent magnet poles disposed in a circumferential direction of the rotor to have circumferential gap between adjoining poles and a stator that has 3n teeth and coils wound around the teeth. The stator core includes a pair of core end plates and a laminate core disposed between the core end plates. Each core end plate has a circumferential width that relates to the gap distance at portions opposite the permanent magnet poles.
