Electric motor works on the principle of magnetic effect of current i.e., when a rectangular coil is placed in a magnetic field and current is passed through it, a force acts on the coil which rotates it continuously.
What is the 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 is the principle of electric motor and 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 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 basic principles enables all electric motors to operate?
The basic principle for all working motors is the magnetic attraction and repulsion. Since a magnet no longer moves once it has attracted, a motor needs some way to manipulate the magnetic fields so that the magnets attract and repel continuously.
What is an electric motor explain with diagram?
An electric motor is a device that converts electrical energy into mechanical energy. Diagram: Electric motor. Working of an electric motor: An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S.
How an electric motor works step by step?
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 are the types of motor?

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.
What are the similarities and dissimilarities between a motor and electric generator?
The motor and the generator are almost similar from the construction point of view, as both have stator and rotor. The main difference between the two is that the Motor is an electric device which converts electrical energy into mechanical energy. The generator is vice versa of that motor.
Is electric motor and DC motor same?
A Primer on Electric Motors
Electric motors are machines that convert electrical energy—from either stored power or a direct electrical connection—into mechanical energy through the production of rotational force. … AC motors, which are powered by alternating current. DC motors, which are powered by direct current.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
What are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
In which case is electric field present?
Answer Expert Verified. Electric field are present when there are electric forces. Electric force can be created when there is a potential difference in the charges of the particles. Cases like rubbing two objects creates static force thus creating electric field.
Which device is magnetic field present?
Generator, DC and AC motor, because it composed magnets that has magnetic field that will move the electrons inside of the copper wires.
Which set ups model the working principle?
The electric generator is a machine for producing electric current or electricity. The electric generator convert mechanical energy into electrical energy. Principle of working of an electric generator: … When the coil rotates it cut the magnetic field lines due to which current is produced in the coil .
