Hi All,
I have a 1988 18hp brushless self exciting generator.
The rotor diodes have failed (open state).
This rotor has four windings connected in series utilizing four diodes.
After hours of research I am unable to come up with a diagram for this arrangement. Every thing I looked at used a three phase winding full wave with six diodes.
I need to know the polarity orientation of the four diodes to re-install them onto the rotor windings.
Additionally I was wondering what the voltage and current requirements for the diodes would be.
I was thinking a Vishay VS series 16 amp 1200 Volt in a DO-4 (DO-203AA) case, similar in size to the old diodes.
Can anyone explain how this ckt operates, current flow etc,,,,,
I have a diagram and pictures.
Any help greatly appreciated.
Thank You
