MAGNETO-GENERATOR AND METHOD OF MANUFACTURING THE SAME

PROBLEM TO BE SOLVED: To obtain the magneto-generator which can reduce the machining cost of a reluctor by reducing the time required for machining the reluctor. SOLUTION: The magneto-generator includes a rotor 1 having a flywheel 3 which is formed in bottomed cylindrical shape, a doughnut-shaped reluctor 4 provided on the outside base of the flywheel 3 and a plurality of magnets 5 provided on the inner circumferential surface of the flywheel 3, a stator 2 provided on the inside of the flywheel 3 and having a laminated iron core 6 which has the outer circumference facing the magnet 5 and a power generation coil 8 provided in the laminated iron core 6, and a signal generator 13 provided on the radial outside of the outer circumferential sidewall surface of the flywheel 3, wherein the reluctor 4 includes a proximal portion 4a formed at the inner circumferential portion, a portion 4b to be detected which is provided on the radial outside of the outer circumferential sidewall surface of the flywheel 3, and a bend 4c formed between the proximal portion 4a and the portion 4b to be detected so that the portion 4b to be detected can face the signal generator 13.
