  Magneto ignition

This type of ignition is intended for mopeds or scooters. It only has three consumers, the ignition and the front and rear lights. Basically, for each of the three there is a type of generator on the anchor-plate, whereby, for the lights there may also be a coil wth two windings.

The exact tension is created for each consumer. Whereby, the tension should actually be high and consistent, which in such a construction is however, hardly possible. Thus, the light, at low revs may be too dim and at max RPM the globe may burn out. However disturbances in the one circuit do not influence the other.

If the power supply should be increased from 6- to 12 volt, a different light-coil must be used or it's winding must be altered. Should this be the case, then the strength of the new lightbulb is also important, because more performance generated than consumed, causes the tension to rise to inadmissable heights.

Modern two-wheelers can, of course, handle halogen light as well as motor cars can, indeed, with only 35 Watts. Thereby, a constantly high light performance can be pretty much guaranteed if the light-armature is laid out stronger and the excess tension is reduced by electronic regulation. Thus, an overall system is developed, also for the brake light and the indicators.

The ignition is basically, no different from that in a motor car engine with contact breaker ignition. Indeed, in this case no battery is needed, however, a car with a generator doesn't need one either, except for the start-up procedure. The windings are very different from those in the light armature, because here, high tension must be built up.

Contact breakers under full switching current need a condenser urgently.

Because we're not dealing with a battery ignition, the force lines of the ignition armature are cut by permanent magnets around the polarity wheel. To do this, the opening of the contact breakers must fit exactly, for this reason, before the actual ignition adjustments are made, the contact breakers must be set at e.g., 0,4 mm. This setting is of course, not applicable in the case of electronic switching.

Flywheels vary depending on the equipment.

The development away from mechanics, or at least, more in the direction of a lower switching current, has also taken place in the field of contact breakers. A stronger ignition coil, outside of the anchor plate, may also be installed. 11/12

Heavy polarity wheels function simultaneously as flywheels.               Top of page               Index
