How does the electric motor function?

Answer 1

An electromagnet is the basis of an electric motor. You can understand how things work in the motor by imagining the following scenario. Say that you created a simple electromagnet by wrapping 100 loops of wire around a nail and connecting it to a battery. The nail would become a magnet and have a north and south pole while the battery is connected.

Now say that you take your nail electromagnet, run an axle through the middle of it and suspend it in the middle of a horseshoe magnet as shown in the figure below. If you were to attach a battery to the electromagnet so that the north end of the nail appeared as shown, the basic law of magnetism tells you what would happen: The north end of the electromagnet would be repelled from the north end of the horseshoe magnet and attracted to the south end of the horseshoe magnet. The south end of the electromagnet would be repelled in a similar way. The nail would move about half a turn and then stop in the position shown.

You can see that this half-turn of motion is simply due to the way magnets naturally attract and repel one another. The key to an electric motor is to then go one step further so that, at the moment that this half-turn of motion completes, the field of the electromagnet flips. The flip causes the electromagnet to completeanother half-turn of motion. You flip the magnetic field just by changing the direction of the electrons flowing in the wire (you do that by flipping the battery over). If the field of the electromagnet were flipped at precisely the right moment at the end of each half-turn of motion, the electric motor would spin freely.

Answer 2

An electric motor works by converting electrical energy into mechanical energy through the interaction of magnetic fields. When current flows through a coil of wire in the presence of a magnetic field, it creates a force that causes the coil to rotate, generating mechanical motion. This rotation can then be used to drive various mechanical systems.

Answer 3

The electric motor function in an easy way. First, the electric motor should have a power input to make the coil heat, its called electromotive force.. In that way the coil and the rotor of a motor will have a called magnetism, so that the rotor cause to move. That is how motor function.

Answer 4

In the simplest design, there are only two parts to consider. The Armature, and the Stator. The armature is the part that revolves, and the fan blades are attached to its shaft. It is made of a permanent magnet. The stator consists of copper windings that conduct electrical input (AC) and generates a rotating magnetic field.

Once the stator's magnetic field is established, it repels the magnetic field of the rotor, which pushes it into rotation. The speed of the field's rotation dictates the speed of the motor.

The are more types of motor that can be used, and they operate differently, but this is a very basic type.
