Definitions

  • a fourth aspect of the present invention is the hub dynamo according to (3), in which the slit portion is formed along the axial direction of the wheel shaft.
  • the coil routing path can be the shortest path.
  • the coil wound around the body portion can be easily routed around the communication portion.
  • a twelfth aspect of the present invention is the hub dynamo according to (11), wherein the bobbin side slit portion formed in the bobbin and extending in the radial direction and the second slit portion are in the axial direction. It is arranged so that it overlaps.
  • FIG. 4 is a perspective view of the stator 13. As shown in FIGS. 3 and 4, the stator 13 is configured by combining a claw pole type first stator unit 20 ⁇ / b> A and a second stator unit 20 ⁇ / b> B in the axial direction of the wheel shaft 11.
  • the stator unit 20A outputs an A-phase alternating current / voltage
  • the second stator unit 20B outputs a B-phase alternating current / voltage.
  • the number A of the teeth portions 102 is set so that the number of magnetic poles of the permanent magnet 19 of the rotor 12 is P.
  • A P / 2 (1) It is set to satisfy.
  • the slit 103 has a role of suppressing an eddy current flowing through the first land 94 a, and a coil 93 through which the coil 93 drawn out from the bobbin 92 toward the axially outer side is inserted. It has a role as a passage part.
  • the slit 103 is disposed between the U-shaped groove 101a and the insertion hole 101b, and extends in the circumferential direction from the radially outer end of the first slit portion 103a extending in the radial direction and the first slit portion 103a.
  • the second slit portion 103b that bends and extends is formed in communication.
  • the formation position of the slit portion 97a is located at the center in the circumferential direction of the U-shaped groove 101a of the land 94a, and the formation position of the slit 97b is the circumferential direction of the U-shaped groove 101a of the Land 94b.
  • the second slit portion 103b overlaps the slit portions 97a and 97b formed in the bobbin 92 in the axial direction. Thereby, the 2nd slit part 103b and each slit part 97a, 97b communicate.
  • a gap K1 having a predetermined dimension is secured between the first stator unit 20A and the second stator unit 20B so as to separate the stator units 20A and 20B in the axial direction.
  • the gap K1 is used as a space for arranging the coil 93.
  • the first stator unit 20A and the second stator unit 20B are combined by shifting the positions of the tooth portions 102 of the respective stator units 20A and 20B by a predetermined angle in the circumferential direction, that is, by shifting the phase. Yes.
  • two-phase alternating currents and voltages of phase A and phase B, which are out of phase are output from the coils 93 of the stator units 20A and 20B.
  • the stator 13 is configured by the two stator units 20A and 20B has been described.
  • the embodiment of the present invention is not limited to this, and the stator 13 may be configured by three or more stator units.
  • the communication portion 96 may be formed on the bobbin 92 of the desired stator unit based on the direction in which the coil 93 wound around each stator unit is pulled out.
  • the case where the five slits 103 were formed in the circumferential direction at equal intervals around the penetration hole 101b in the side plate part 101 of each of the land 94a, 94b was explained.
  • the number of slits 103 is not limited to five.
