What is line current in A motor?

So, as line current = armature current + field current, and field current is negligible compared to armature current, we can approximate line current to armature current. Yes, torque is proportional to armature current in a dc shunt motor.

What is armature current?

In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The first is to carry current across the field, thus creating shaft torque in a rotating machine or force in a linear machine.

What is line current in generator?

Line current is the current magnitude flowing in any conductor connecting the source to the load, excluding ground or common. Consider the delta-delta system of Figure 9.3. 1. We have already established that the voltage developed by generator A,B must be the same as the voltage across the load A′,B′.

What is a line current?

Line current is the measured amount of direct current flowing in a pipeline. It is an indicator of the degree of reactivity and corrosion experienced on the pipeline’s surface.

What is line current vs phase current?

Line current is the current through any one line between a three-phase source and load. Phase current is the current through any one component comprising a three-phase source or load.

What is the difference between armature current and field current?

The field of a machine is the part that generates the direct magnetic field. The current in the field does not alternate. The armature winding is that which generates or has an alternating voltage applied to it.

What is the relationship between the armature current and the field current?

Since you specified a DC machine, field current and armature current must be equal, as all current across elements of a SERIES circuit is constant and not divided as it is in a parallel circuit. That is to say that as current increases in the DC machine, both field and armature current increase equally.

How do you calculate full load of armature current?

Full load current I, I =P. / 1.732 * V Amps.

What is armature current of DC motor?

The stator consists of field windings while the rotor (also called the armature) consists of an armature winding. When both the armature and the field windings are excited by a DC supply, current flows through the windings and a magnetic flux proportional to the current is produced.

Is line current and phase current?
