The armature is the part of an electric generator or motor that contains the main current-carrying winding. It usually consists of a coil of copper wire that is wound around an iron or steel core. The coil and core are placed in a magnetic field, which is produced by one or more permanent magnets or electromagnets.

How do you use armature in a sentence?
The children all made a small armature with soft metal rods.
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 material is armature made from the bulb?
The armature of a bulb is typically made from tungsten wire. This material is chosen because of its high melting point, which allows the bulb filament to operate efficiently at high temperatures without degrading quickly.
Where the armature winding coil placed?
The armature winding coil is typically placed on the rotor of an electrical machine, such as a motor or generator. In a rotating machine, the armature winding is situated on the core, which is often made of laminated iron to reduce eddy current losses. In some designs, such as in certain types of generators, the armature can also be located on the stator. The placement of the armature winding is crucial for the efficient generation of magnetic fields and the conversion of electrical energy.
What metal is Statue of Liberty mostly made of?
Copper plates on a steel armature structure.
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 is meant by core in electrical machine?
The armature center of a d.c. machine is typically made of overlaid sheets keeping in mind the end goal to, (a) lessen hysteresis misfortune , (b) diminish armature copper misfortunes.
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.
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.
