What is an armature and what is its function?

Armature: It is a rectangular iron core wrapped by the copper coil through which electricity passes and due to magnetic field it experiences a force and rotates. Brushes: It conducts current between stationary wires and moving parts, most commonly in a rotating shaft.

What is the function of armature in electric motor Class 10?

The main function of the armature is to rotate the shaft or axel to which it is attached.

What is the use of armature in DC generator?

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.

Why is armature important?

This framework provides structure and stability, especially when a plastic material such as wax, newspaper 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 function of armature coil and split rings in an electric motor?

1) Armature- Rotates when electric current is passed hence its kinetic energy can be used for various purposes. 2) Brushes- Maintains contact of the armature coil with the main circuit while rotating. 3) Split Rings- Prevents the rotation of the main circuit while the rotation of armature coil.

What is armature of motor?

In electrical engineering, an armature is the component of an electric motor which carries alternating Current. The armature must carry Current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, Torque (rotating machine), or force (linear machine).

How does armature rotate in DC motor?

The armature is mounted on bearings and is free to rotate. It is mounted in the magnetic field produced by permanent magnets or current passing through coils of wire, which are called the field coils. When a current passes through the armature coil, forces act on the coil and result in rotation.

What is armature voltage in a DC motor?

Armature voltage is the voltage developed at the terminals of the armature winding of an AC or a DC machine during generation of power. Formula to calculate DC motor armature voltage: Amature voltage in volts = V = k η Φ

What is the function of armature winding?

It produces a flux that is used for the development of power inside the machine such that the motor is able to rotate. The winding wound on the core is given current through a DC supply. This current-carrying winding as under the influence of the magnetic field develops a force that develops a rotational torque.

What is the function of armature and commutator?

Key Difference between Armature & Commutator
