How does a motor 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 .

How does a motor work?

How do motors work? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. … Electric Motors have an array of applications.

How does a motor work in order?

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.

How do I know if a motor is AC or DC?

Look for the stator core construction and rotor. If there is no commutator, then it is a AC motor. If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor).

What are the six parts of a simple 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 are the three basic parts of an electric motor?

Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.

How can you create a strong electromagnet?

You can make an electromagnet stronger by doing these things:

  1. wrapping the coil around a piece of iron (such as an iron nail)
  2. adding more turns to the coil.
  3. increasing the current flowing through the coil.

What is Fleming’s left hand rule?

The direction of the force can be found using Fleming’s left-hand rule. Hold your thumb, forefinger and second finger at right angles to each other: the forefinger is lined up with magnetic field lines pointing from north to south. the second finger is lined up with the current pointing from positive to negative.

Is it possible to make the motor turn in the opposite direction?

In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
