Definitions:

Armature Excitation

The process of applying voltage to the armature winding of a generator or motor, which induces magnetic fields and enables motion or power generation.

Cumulative-compound

A term that could be misinterpreted outside a specific context; without additional information, it suggests a complex or combined effect or entity, possibly accumulating over time. NO

Shunt Field

A magnetic field created by a shunt winding in electrical machinery, used for regulation of the machinery's operation.

Series Field

A set of windings in a DC machine or certain types of AC machines connected in series with the armature circuit to create magnetic fields for electromechanical energy conversion.
