CAPACITOR CHARGING #2 CDM
The flywheel rotates the permanent magnets
past the capacitor charging coils–causing the
coils to produce AC voltage (260–320 volts).
The opposite voltage pulse is then conducted to
the CAPACITOR DISCHARGE MODULES
(CDM), where it is rectified (DC) and stored in a
capacitor. The stator voltage return path is
through the ground wire of the other CDM and
back through that CDM’s charging coil wire to the
capacitor charging coils.
