A method is disclosed for manufacturing a flywheel magneto of the radial magnetic flux type for motor bicycles, motor scooters and the like, which comprises the steps of forming a sub-assembly comprised of a ring, the magnets, the pole shoes by scotching said ring on a plurality of wedges placed around a cylindrical body whereafter the pole shoes and an inner ring of a metallic nonmagnetic material are positioned and a punch rams all these component parts forcibly together. Finally, the sub-assembly so composed is surrounded by a casting of a nonmagnetic material. |
