really want to ge this polarization thing correct
with positve 6 volt ground
1. External grd field, internal sourced field type A, 2 brush
polarization: field terminal to negative bat terminal
2. External grd field, internal sourced field, type A, 3 brush
polarization: field terminal to negative bat terminal
3. Internal grd field, internal sourced field, type A, 3 brush
polarization: armature terminal to negative bat terminal
4. Internal grd field, external sourced field, TYPE B, 2 brush
polarization: armature terminal to negative bat terminal
NAA model
Is the above correct, want get it right!
Understand the field is not permanent magnetics so the iron core must magnetized with the wire coil. The polarization gets the current working in the same direction as the armature generated current for a shut wound generator where the field coil and armature are in parallel.
