Engine: Electricity

1. A These large poles are placed in the magnetic neutral plane between the main field poles and are designed to eliminate or reduce sparking caused by inductance of the field coils.
2. B These windings are wound on the main field poles and are designed to eliminate or reduce sparking caused by inductance of the field coils.
3. C These windings are wound on the main field poles and are designed to eliminate or reduce sparking caused by inductance of the armature coils.
4. D These narrow poles are placed in the magnetic neutral plane between the main field poles and are designed to eliminate or reduce sparking caused by inductance of the armature coils.
