PROBLEM TO BE SOLVED: To enhance generation efficiency, by leading the magnetic flux from the magnet of a rotor effectively to the stator teeth of a stator, thereby enhancing the power generation output.SOLUTION: A motor cycle generator has a stator 33 in which a coil 37 is wound around a plurality of stator teeth 35 extending radially from the center, and a rotor 34 where a magnet 41 is installed on the inner peripheral surface of a rotor yoke 40 and rotates about the stator 33. In the motor cycle generator, a plurality of magnets 41 are installed adjacently through a gap 42 in the circumferential direction, and the stator teeth 35 is constituted by laminating a plurality of core sheets of thin steel plate, and has a tip 38 extending from the coil winding part 36 where the coil 37 is wound to the opposite ends in the circumferential direction. One side part of the stator teeth tip extending to the rotational direction side of the rotor is configured to overlap a preceding magnet adjacent to the front end in the rotational direction, when the front end of the magnet in the rotational direction is substantially aligned with the center line of the coil winding part. |
