摘要： PURPOSE:To form a projection easily at a low cost, by forming a ring-formed salient strip including the projection, on the outer peripheral surface of material for manufacturing a fly-wheel, by means of machining, and by avoiding unnecessary sections by means of shearing in the direction in parallel with the axial core of a cylindrical section. CONSTITUTION:A cup-formed fly-wheel 6 has a ring-formed salient strip 6c formed by machining the outer peripheral surface of bottom-covered cylindrical material. On the upper edge of a fly-wheel bearer 11, grooves 11a confronted with unnecessary sections B are arranged. On the lower edge of a metallic mold 10, tooth forms 10a confronted with the unnecessary sections B are arranged. The cup-formed fly-wheel 6 of a semiproduct is put on the fly-wheel bearer 11, and the metallic mold 10 is externally fitted on the cup-formed fly- wheel 6 and is pressure-moved down with a press. As a result, on the ring- formed salient strip 6c, necessary sections A are left, and the unnecessary sections B are removed by means of shearing.

摘要： PURPOSE:To improve working efficiency and reliability, by a method wherein the connecting work of the coil end leading part of a winding coil is effected in a condition that varnish coating process is not applied yet. CONSTITUTION:The coil end leading part of a winding coil 1 is pulled out of the end face thereof outwardly in the radial direction of a stator 2 and the leading part of an extermal lead wire 5 is superposed thereon. Subsequently, the leading part is dipped into a solder melt tank to connect them by soldering. The connecting part 4, soldered to the lead wire, is bent to the axial direction of the stator 2 and is pushed into a V-shape gap between winding coils 1; thereafter, the connecting part 4 is mounted into the gap by utilizing the heat of the coil which accompanies the varnish coating process.

摘要： PURPOSE:To permit to reduce variability of the operational interval of an ignition control circuit by a method wherein gaps between ignition signal coils, arranged so as to be corresponding to the number of cylinders, and magnets for exciting are corrected respectively so as to be corresponding to the deviations of output waveform caused by external leakage fluxes. CONSTITUTION:The gaps between the ignition signal coils 81-83, arranged so as to be corresponding to the number of cylinders, and the exciting magnets 9 are corrected individually so as to be corresponding to the deviations of output waveforms of the ignition signal coils, which are caused by the external leakage fluxes, by adjusting the other gaps delta2, delta3 based on the gap delta1 between the coil 81 and the magnet 9. Accordingly, the variabilities in the operational intervals of the ignition control circuit may be reduced regardless of a high- speed area or a low-speed area even under magnetic fields in which the affections of external leakage fluxes to the ignition signal coils are different respectively.

摘要： PURPOSE:To lessen the effect of leakage magnetic flux of a magneto generator for protecting the strength of its boss from lowering by providing the flywheel with large and small cylindrical parts to which prescribed permanent magnets are fixed. CONSTITUTION:A flywheel yoke 4 is composed of large and small cylindrical parts. The inner circumference face of the small cylindrical part is fixed to a boss 2 fitted on a drive shaft 1. Two or more permanent magnets 5 and pole pieces 6 for the main charging excitation are fixed to the inner circumference face of the large cylindrical part, and a permanent magnet 9 for the ignition signal generation excitation is arranged on the inner circumference face of the small cylindrical part. An ignition signal generation coil 11 is installed to an iron core 10 opposed to the magnet 9 through a gap. Thus, since the small cylindrical part shields leakage magnetic flux to an ignition signal generator, a stable ignition-signal can be obtained, and the constitution eliminates the need for embedding the permanent magnet 9 for the ignition signal generation excitation into the boss 2.

摘要： PURPOSE:To improve the generating efficiency of a magnet generator by mounting a centrifugal fan on the inside surface of a flywheel, thereby efficiently cooling a generating coil and a magnet. CONSTITUTION:A centrifugal fan 214 is mounted on the inside side surface of a flywheel 21. Then, gas which has relatively low temperature at the side of an engine cover 13, to which a stator is secured is circulated to the surface of a generating coil 222 to remove the heat generated at the coil and to simultaneously cool a magnet 211, thereby suppressing the decrease in the exciting force. Then, the copper loss of the heat generating coil decreases, and the decrease in the exciting force of the magnet is suppressed. Accordingly, the generating efficiency is improved, and the lifetime of an insulating material used for the generating coil can be increased.

摘要： PURPOSE:To decrease the number of parts and assembling manhour so as to reduce the cost, by forming a flange at the outside periphery with a rotor unifiedly. CONSTITUTION:A rotor 11 is manufactured by shaping a flat plate, which is excellent is formability and in deep drawing property, into a bowl-like form, and simultaneously, forming a flange 14 by drawing a portion of the outer periphery of the bowl. Then a notch 16 is made by press-cutting at the prescribed position of the flange. Hereby a rotor 11 is manufactured. Because the rotor 11 is formed in one body with the flange 14 at the outside periphery, the number of parts is smaller than conventional rotors, and no troubles due to loosening of joint are caused and the mechanical strength of the rotor itself is increased because of the stiffness of the flange.
