How do you distinguish between field and armature winding?

Armature Winding is the winding, in which voltage is induced. Field Winding is the winding in which the main field flux is produced when the current through the winding is passed.

What is the difference between field current and armature 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 are different types of connections possible between armature and field windings in a DC machine?

There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.

What are different types of connections possible between armature and field windings in a dc machine?

Which of the following winding is connected in series with armature winding of DC machine?

inter-pole winding
Inter-poles are similar to the main field poles and located on the yoke between the main field poles. The inter-pole winding is connected in series with the armature winding because the inter-pole must produce flux that is directly proportional to the armature current.

Which part will surely tell that given machine is DC machine and not an AC type?

Commutator
Commutator will surely tell that given motor is DC motor and not an AC type.

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.

What is the relationship of the armature voltage and field current?

Based on the experiment I conducted, the data shows that the armature voltage is directly proportional to the field current.

How is armature winding of a DC machine done?

Basically armature winding of a DC machine is wound by one of the two methods, lap winding or wave winding. The difference between these two is merely due to the end connections and commutator connections of the conductor. To know how armature winding is done, it is essential to know the following terminologies –

What is the behaviour of the armature circuit?

The armature circuit behaviour is dependent on the flux in machine. Traditionally the flux is produced and controlled by a field winding. Many modern DC machines are constructed with a permanent magnet (PM) field, which results in a constant flux. In a PM DC machine, the armature circuit model is the complete circuit model, and k ϕ is constant.

What is the armature of a DC motor?

DC Armature The armature of an electric machine is the name historically given to the winding where a voltage is induced and power transfer between electrical and mechanical systems occurs. It is a term used in dc machines and ac synchronous machines. In a dc machine, the armature is the rotating circuit.
