WebFeb 24, 2024 · There is a primary circuit (control circuit) and a secondary circuit (load circuit) in the relay. The primary circuit consists of an electromagnetic coil of wire wrapped around a soft iron core and a movable armature. The armature and the coil are separated by a small air gap when the coil is not energized. WebAug 2, 2024 · When the armature and field windings are connected in parallel, the motor is referred to as a “shunt wound” DC motor. (In electrical parlance, a parallel circuit is referred to as a shunt.) The parallel connection between the windings means the current supplied to the motor is divided between the armature and the field (I total = I a + I f ...
