PURPOSE:To achieve single ignition per single rotation reliably by winding a firing source coil such as capacitor charging coil across two salient poles adjoining each other and bringing the output voltage at unnecessary portion to zero through cancelling of flux. CONSTITUTION:A plurality of magnets 2 are arranged in ring on the innercircumference of iron arm 1 made of magnetic member directly coupled to crank shaft and rotated. The magnets 2a-2e are magnetized such that N-pole is produced at the inner diameter side while magnets 2f-2l are magnetized to produce S and N poles alternatively. A star core 3 made of laminated magnetic iron plates is contained at the inside of said ring magnet 2 where the salient poles 3a, 3b in those 3a-3l projecting radially outward are used for charging of capacitor while 3c-3l are used for lighting or battery charging. Then capacitor charging coil 4 is wound across said poles 3a, 3b while output salient pole 5 is wound over the salient poles 3c-3l. |
