PURPOSE:To decrease the flicker rotating speed of a lamp with a simple construction by winding output coils on salient poles of a core of a magnet rotor of multipolar array in a partly jumped manner. CONSTITUTION:A multipolar magnet generator 3 is irregularly magnetized on the inner surface of a cup-shaped rotor 1 so that two or more poles of the same polarity are continued and the remaining portions are alternately magnetized at N-poles and S-poles at 12-pole ring-shaped magnet 12. A core 3 for forming a magnetic circuit has 10 salient poles 3b-3k and an igniting salient pole 3a. In this case, coil windings P1-P8 are wound on four continuous salient poles 3b- 3e, the later two salient poles 3f, 3g are jumped, and wound on the next four poles, coil windings P9, P10 are further wound on the jumped salient poles 3g, 3f, and connected in series. When the rotor 1 rotates, a voltage is generated at a charging coil 4 of a capacitor to charge it, and then abruptly discharged to ignite a high voltage at an ignition plug. |
