Abstract

For use with ignition units of internal combustion engines, the magnetic generator comprises rotary magnet wheel with several main magnets carrying the pole-shoes for generation of the spark ignition energy in at least one winding of a fixed (stationary) armature, has the main and control pole shoes mfd. together and fixed in the magnet wheel(11). Moreover, a uniform magnetic field distribution is achieved between the main and control magnets. The control pole shoe is fixed on to the pole shoe(17a) of the main magnet(16a) with an inserted magnetically inactive frame, or rack, to provide uniform spacing of both pole shoes.
