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.
How does a simple motor work physics?
This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.
What is the working principle of 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.
How do motors work BBC Bitesize?
Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. This is called the motor effect .
What is a simple motor?
The simple motor built in class uses a coil that is a temporary electromagnet. This coil gets the force to help create torque from the electrical current supplied by the battery. The donut magnet used in the motor is a permanent magnet, which means it has a north and a south pole that are permanently in place.
What are the types of motors?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
- DC Brushless Motors. …
- Direct Drive. …
- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
How can a motor be used?
This force creates a torque on a loop of wire present in the magnetic field, which causes the motor to spin and perform useful work. … Motors are used in a wide range of applications, such as fans, power tools, appliances, electric vehicles, and hybrid cars.
What is Motor and its types?
A synchronous motor is a doubly excited machine, meaning it includes two electrical inputs. In a common three-phase synchronous motor, one input, usually three-phase AC, supplies the stator winding to produce three-phase, rotating magnetic flux. The rotor supply is usually DC, which excites or starts the rotor.
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 is electric motor and its principle and working?
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 principle of motor and generator?
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 basic principle of generator?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.
How a motor works GCSE physics?
A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.
What is Fleming’s left hand rule?
Fleming’s left-hand rule states that:
When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow. It was invented by John Ambrose Fleming.
Why will a motor not work without a commutator?
No, a direct current motor cannot run without a commutator because there is no induced electromotive force inside the armature. The commutator plays the function of supplying current to the armature from the brush. That is why the armature removed will not supply the motor.
