PURPOSE:To increase the output in a simple constitution and to obtain the accurate ignition output by providing the relative length to the rotor pole length and by providing two pieces of the ignition source coil both of which are connected cumulatively and differentially. CONSTITUTION:On the inside circumference of a flywheel 1 magnets 2 having more than six poles, e.g. alternately magnetized at eight N and S poles, are provided. A magnet 2a, one of these magnets, is more than 360 deg./P in magnetizing length at N pole and less than 360 deg./P in magnetizing length at S pole, the sum being (2X360 deg.)/P (P: the number of magnetized poles of a magnet). In addition, as the occasion demands, less than (P/2-1) pieces of the magnet 2a are provided. On the other hand, to a stator 3 provided are a pole 7 of multiple generating coils 6, poles 5 and 5a of two ignition source coils 4 and 4a. In this case, the space between the poles 5 and 5a is to be nX360 deg./P (provided that n is an integer). Both coils 4 and 4a are connected in series cumulatively or differentially, the one of the voltage outputted being for the igniting source and the other for the ignition signal.
