The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil .
How does electric motor work explain?
The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil .
How does an electric motor work explain with diagram?
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. Now, current is passed through it continuously. When current is passed into the coil, it produces a magnetic field around it.
How does a simple motor converts energy?
Motors consist of loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts a torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process .
What are the three basic parts of an electric motor?
Motor Basics
No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor . Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
How do electric motors rotate?
Large AC motors (used in things like factory machines) work in a slightly different way: they pass alternating current through opposing pairs of magnets to create a rotating magnetic field, which “induces” (creates) a magnetic field in the motor's rotor, causing it to spin around.
How are electric motors made?
A three-phase, four-pole induction motor is made of two main parts: a stator and a rotor . The stator is made of three parts: a stator core, conducting wire, and frame. The stator core is a group of steel rings that are insulated from one another and then laminated together.
What is the working of electric motor Class 10?
Principle of Electric Motor
The principle of the electric motor is based on the fact that a current carrying conductor produces a magnetic field around it . A current carrying conductor placed perpendicular to magnetic field experiences a force.
What are the 6 parts of an electric motor?

- What Do All of These Components Have in Common?
Can a motor produce electricity?
You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use . Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.
Does turning an electric motor generate electricity?
An electric motor does the opposite of an electric generator. Instead of turning mechanical energy into electricity, an electric motor takes electricity and converts it into mechanical energy .
What is the transfer of energy in a motor?
We supply electrical energy to an electric motor. An efficient motor transfers most of this energy as kinetic energy (useful work). Only a small fraction is wasted as it heats up the surroundings.
What are the 7 parts of electric motor?
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
- Commutator.
- Brushes.
- Axle.
What are the two main components of an electric motor?
An electric motor consists of two major parts, the rotor and stator (see Figure 5).
What is inside electric motors?
A simple motor has six parts: an armature or rotor, a commutator, brushes, an axle, a field magnet, and a DC power supply of some kind .
Why do DC motors spin?
When the motor is powered by DC current, a magnetic field is created within the stator, attracting and repelling the magnets on the rotor . This causes the rotor to start rotating. To keep the rotor rotating, the motor has a commutator.
Why split rings are used in electric motor?
Answer. The purpose of split ring is to reverse flow of current after every half rotation of the coil and make coil rotate in a single direction . If split ring was not used in an electric motor, the coil would have rotated half in clockwise direction and half in anticlockwise direction.
What is the direction of electric motor?
Electric motors are designed either for clockwise rotation, or counter-clockwise, or both . This is very simple. The IEC standard says that the direction of rotation is always viewed from the driven end side, where the load is.
Why DC motor is not used in EV?
The only “DC” motor which does not require some form of inverter or electronic switching system is the mechanical brushed motor. These are so unsuited to the task of light weight variable speed drives that there will be few if any used in modern electric car designs.
How does a motor work physics?
An electric motor converts electrical energy into physical movement . Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric motors are used in all sorts of applications.
Why are magnets used in electric motor?
Magnets are a primary component in electric motors. In order to work they need to be made of a coil of wire that can spin and is encircled by strong magnets. When an electric current is induced in the coil, it emits a magnetic field, opposing the magnetic field emitted by the strong magnets.
