<p>PROBLEM TO BE SOLVED: To provide a hub dynamo in which flickering of light emission can be suppressed when power is supplied to an LED, and cost reduction and compaction are possible with simple configuration.SOLUTION: A rotor has a permanent magnet in the inner peripheral part. A stator 13 is constituted by combining a first stator unit 20A and a second stator unit 20B each including a stator core 26 and a coil in the axial direction. The stator core 26 has teeth 22 facing a permanent magnet in the outer peripheral part, and the first and second stator units are combined while shifting the position of the teeth 22 of each stator unit by an angleα. The angleαis 1/2 of the pitch of teeth, and two-phase AC current and voltage having a 90° phase shift of electrical angle are outputted.</p> |
