for DKW SB500 

Magnet based generator with integrated  ignition. Output at 12V/80W DC. Solid state ignition. Replaces old dynamo, points, centrifugal governor, ignition coils.  
Ignition ist static as with the modern carburants and the high tension ignition there is no need to have reduced advance at startup (we have tested that). Rotor is at 2kg much lighter than original over 6kg rotor. This helps the engine to turn more freely and reduces wear on the main bearings. No changes on engine reguired, fits as original dynamo.
This system differs electrically to most of our other systems. It is a magneto and a battery ignition at the same time. On that basis it could be made so small, lightweight and still very powerful with full 40.000 volts spark from the first revolution onwards. Power consumption is maximally 15 watts, but significantly less at medium revs as there the magnet based system produces most of the needed energy. With 80 watts light circuitry output there is no risk of a flat battery.
advantage over original system
  • the system is available (DKW system is not)
  • all parts are new
  • more light output (you may use a 12V/40-45 Watt)
  • very stable ignition with solid spark
  • better starting, better fuel burning
  • no wear anymore on points
  • no delicate centrigugal governor any more
  • much reduced wear on crank bearings due to reduced rotor weight
