Armature amps refer to the current flowing through the armature winding of an electric motor or generator. It is used to power the electromagnetic coils that generate the magnetic field needed for the motor or generator to operate efficiently. Monitoring armature amps is crucial for maintaining the proper functioning and performance of the motor or generator.

What is mean by armature reaction?
armature reaction means when load is added to the armature then current is passed through armature conductors then in armature creates flux. It is demagnetize and cross magnetize the main field flux. in other ward it is effect of armature field on main field.
200ma in amps?
200ma is .200 amps or .2 amps
When a current flows through an electric bell what will happen to the armature?
When a current flows through an electric bell, it creates a magnetic field that causes the armature, attached to a spring, to be attracted towards the electromagnet. This movement causes the armature to strike the bell, producing a ringing sound.
How do you convert HV amps to LV amps?
To convert high voltage (HV) amps to low voltage (LV) amps, you can use the formula: HV amps = LV amps x (LV voltage / HV voltage). By rearranging the formula, you can calculate LV amps by dividing HV amps by the ratio of HV voltage to LV voltage.
How many amps is 3000 milliamps?
3000 milliamps is equal to 3 amps. To convert milliamps to amps, you divide by 1000.
Can you describe the speed of Dc series wound motor as a function of the series resistance of armature?
resistance of the armature is more related to the current going thru it 250v Dc 5hp motor 20 a 12ohms 1/2hp 2 amps 120 ohms the speed will be related to the number of poles
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
What are v and inverted v curves?
V Curve- Excitation vs Armature currentV curve is the graph showing the relation of armature current as a function of field current in synchronous machines. The purpose of the curve is to show the variation in the magnitude of the armature current as the excitation voltage of the machine is varied.Inverted V Curve- Excitation vs Power FactorThe synchronous motor "V Curves" shown above illustrate the effect of excitation (field amps) on the armature (stator) amps and on system power factor. There are separate "V" Curves for No-Load and Full-Load and sometimes the motor manufacturer publishes curves for 25%, 50%, and 75% load. Note that the Armature Amperage and Power Factor "V" Curves are actually inverted "V's".Assume it is desired to determine the field excitation which will produce unity power factor operation at full motor load. Project across from the unity power factor (100%) operating point on the Y-Axis to the peak of the inverted Power Factor "V" Curve (blue line). From this intersection, project down (red line) from the full-load unity power factor (100%) operating point to determine the required field current on the X-Axis.In this example the required DC field current is shown to be just over 10 amps. Note at unity power factor operation the armature (stator) full-load amps is at the minimum value.Increasing the field amps above the value required for unity power factor operation will cause the machine to run with a leading power factor, while field weakening caused the motor power factor to become lagging. When the motor runs either leading or lagging, the armature (stator) amps increases above the unity power factor value.
Why dc shunt generator does not have armature resistance?
It does have armature resistance.
Difference between 12volt armature and 24 volt armature?
The main difference between a 12-volt armature and a 24-volt armature is the voltage rating at which they operate. A 12-volt armature is designed to run on a 12-volt electrical system, while a 24-volt armature is designed for a 24-volt electrical system. This difference determines the power and speed capabilities of the armature when used in electrical devices.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
What is armature reactions in a synchronous machine?
Armature reaction is the effect of armature flux on the flux generated by the fied windings.Cross magnetisation and Demagnetising are its consequences.
What is the function of armature core in dc generator?
this is wer the armature conductors ar being mounted,therefor it helps the flexibility of armature conductors.
The installation of an advancing armature in place of a standard armature can result in severe kickback?
no
What is mean by armature reaction?

What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)
Why the induction motor does not have armature reaction?
Because the armature (or rotor) has no external connection. The currents that produce torque from the rotor are induced by the magnetic field in the machine, so there is no commutator, no brushes and no armature reaction.
