The usual case of a WiaD is conversion of an industrial 460 volt machine to a residential or commercial or light industrial 230 volt premises.
The less usual case is conversion of a residential or commercial or light industrial 230 volt machine to a 460 volt premises.
By making a single cut (wire deletion) and a single component addition (a 2:1 or 1:2 control transformer) both of these changes can be made without further changes to the machine.
Meaning: no need to track down the "unobtanium" C-H magnetic starter coil, and no need to track down the "unaffordium" C16J and 3C23 filament transformers.
The first attachment shows the modified WiaD input section and a schematic of the revised wiring which includes the new control transformer, which is a common 230:460 300 V-A unit.
The second attachment shows the revised WiaD field regulator with the one wire change.
The third attachment shows the revised WiaD armature regulator with the one wire change.
This conversion is "universal" in that it may be employed to convert any 230 volt machine to 460 volts, or any 460 volt machine to 230 volts, using the same components.
