What is the working of an electric 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 torque applied on the motor’s shaft.

What is the working of electric motor Class 10?

An electrical machine through which we can convert electrical energy into mechanical energy is called an electric motor. A force is generated due to the interaction between the magnetic field of the motor and the current flowing through a wire winding. This force acts as a torque on the motor shaft and makes it rotate.

What is the working principle of an 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 are the main parts of an electric motor?

Motor Components

The components of an electric motor may include a rotor, thin sheets of stacked metal called laminations, a stator, wire windings, magnets, a commutator, brushes, poles, electrical interconnects and a housing.

What is the role of commutator in electric motor?

The commutator assures that the current from the generator always flows in one direction. … 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.

How many types of electric motors are there?

Two Types of Electric Motors

There are at least a dozen different types of electric motors, but there are two main classifications: alternating current (AC) or direct current (DC).

Why are electric motors important?

More than 40% of generated electricity is consumed by industry, and two-thirds of that energy is used by electric motors. By using more efficient motors it would be possible to achieve huge savings in both energy and carbon dioxide emissions.

What is the function of brushes in electric motor?

A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators.

What is the principle of electric motor and electric generator?

Electric generator follows Fleming’s right-hand rule. The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field. The working principle of generator is based on electromagnetic induction.

What effect of electric current is used in electric motors?

Answer: An electric motor converts electrical energy into mechanical energy using the magnetic effect of electricity. In an electric motor, a rectangular coil is suspended between the two poles of a magnetic field.
