Abstract
The invention has for its object to solve the problem associated with the use of a flywheel magneto for supplying ignition power to multiple cylinder combustion engines. The flywheel magneto according to the invention is composed of a flywheel (1) supporting magnets arranged in groups (2, 3, 4, 5-6, 7, 8, 9). The magneto flywheel (1) coacts with a multi-leg (11-20) core (10) of magnetically conducting material, the spacing or pitch of the core legs being such that the number of legs form an integer whereas half this number has to form an odd number. Within each group the magnets (2-9) are spaced in agreement with said core pitch. Said groups (2, 3, 4, 5-6, 7, 8, 9) are separated two pitches. Two adjacent core legs (11, 12) are provided with like windings (21, 22) the outputs ends (23, 24, 25) of the windings being connected to a discriminator circuit which distributes, in dependence of series of voltage polarities, trigger pulses (37, (37, 38) to ignition circuits (39, 40) for the respective engine cylinder (41, 42). The remaining core legs can accommodate, for example, generator windings (26).
