In sculpture, an armature is a framework around which the sculpture is built. This framework provides structure and stability, especially when a plastic material such as wax or clay is being used as the medium. When sculpting the human figure, the armature is analogous to the major skeleton and has essentially the same purpose: to hold the body erect.

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.
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 armature reaction in dc machines?
Armature reaction is the phenomenon in DC machines where the magnetic field produced by the current flowing in the armature windings interacts with the main magnetic field produced by the field windings. This interaction can distort the main magnetic field, causing changes in the machine's performance such as voltage regulation and torque production. Measures such as interpoles or compensating windings are used to counteract the effects of armature reaction in DC machines.
How do commutating field windings cope with the effect of armature reaction?
Commutating field windings are connected in series with the armature windings so that the current flowing in the coils is always equal to the armature current. The number of turns in the commutating field windings are also equal to the number of armature turns. This means that the field strength of the commutating windings and the field strength of the armature are always equal. A DC motor is constructed so that these two fields of equal strength oppose one another, they therefore cancel one another out. The main field is now unaffected by armature reaction.
What part of an electric motor repels the poles of the permanent magnets?
The armature of an electric motor is the part that repels the poles of the permanent magnets due to the flow of electric current through the conductors in the armature, creating a magnetic field that interacts with the magnetic field of the permanent magnets to produce motion.
What is the purpose of a growler test?
I think it's a test for a shorted armature.
What is the purpose of Inter-pole fitted in a DC generator?
to chancel the effect of the armature reaction.
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.
How do you Reverse direction on a DC motor?
a general purpose D-C motor can be reversed by changing the polarity of either the armature or the field but not both
Why dc shunt generator does not have armature resistance?
It does have armature resistance.
Difference between 12volt armature and 24 volt armature?

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?
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.
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.)
