The proper rotation of the motors is the basis of many appliances. The rotating movement is so evident at times, as in fans or cakes, but it can remain camouflaged, as in the operation of washing machines or in the up and down movement of the electric windows of car windows.

To know how an electric motor turns and how the processes are different from each other, we begin by having to examine its basic components. First we check the concept of repulsion or attraction between magnetic poles 120996.00 leeson, and in another more advanced stage we will check the concept of the action of the magnetic fields on the currents.

The motor rotor originates the side to which the motor will rotate and it will need a torque to start its rotation, which is usually produced by magnetic forces developed between the rotor and stator magnetic poles. These pulling or pulling forces will pull and push the moving parts of the rotor, producing torques and motions that cause the rotor to rotate faster, until the frictions or loads attached to the shaft decrease the resulting torque to the ‘zero’ value, when the rotor rotates with a stable angular velocity.
