Frequent question: What is the function of armature coil in electric motor Class 10?

5) Armature Coil: It helps the motor to run. 6) Brushes: It is a device that conducts current between stationary wires and moving parts, most commonly the rotating shaft.

What is the function of armature coil?

In electrical engineering, an armature is the component of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors.

What is the function of armature coil in an electric motor?

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 role of armature in electric motor Class 10?

Armature – It is a rectangular coil that is placed in a uniform magnetic field. The main function of the armature is to rotate the shaft or axel to which it is attached. … The work of the split ring is to change the direction of current and which leads the rotation of the armature in the same direction.

What are the functions of an armature coil and split ring in 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 the principle of DC motor Class 10?

Principle : It works on the principle of motion of a current carrying conductor in a magnetic field, according to Fleming’s Left Hand Rule. It is a device which converts electrical energy into mechanical energy of rotation.

What is the function of commutator?

On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.

What is the role of brush in electric motor?

IN ELECTRIC MOTOR the function of brushes is to make contact with the rotating rings and through them to supply current to the coil. function of commutator in an electric motor is to reverse the direction of current through the coil periodically.

What is the basic principle of electric motor?

The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.

What is electric motor class 10th?

The Electric Motor. An electric motor is used to convert electrical energy into mechanical energy. … Motors convert electric energy to mechanical work. The opposite is done by generators that convert mechanical work to electrical energy.

What is the role of carbon brushes in electric motor Class 10?

The primary function of carbon brushes is to deliver or collect current from a rotating part of an electric machine. The brushes should maintain a close contact with rotating part (commutator or slip rings) in order to ensure sparkles operation without wearing itself too quickly.

What is the use of armature in a motor?

An armature is used as an electric motor or generator. The armature is used to communicate between two magnetic fluxes. When the armature is used as an electric motor, due to relative motion between flux produced by the field winding and the flux produced by the armature winding the EMF is induced.

What is the function of motor?

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.

What is armature reaction?

: a magnetomotive force set up by the current induced in the armature of a dynamo that results in altering as to both magnitude and direction the flux due to the field magnet.
