Electric motors are responsible for much of the energy consumption in industries. In the industrial sector between 50 and 60% of the electric energy used is consumed by these machines, so the importance and necessity of using ever more efficient motors. All the electric motors are constituted by a winding or coil where the magnetic field arises and this phenomenon appears in the fixed part of the motor that when subject to a magnetic field created by the electric current receives the name of inductor. The same phenomenon appears in the moving part which is where induced electromotive forces will appear, is called induced.
When an electric current passes through a conductor, a magnetic field is created around it. If this conductor is in a region of fixed magnetic field, the conductor will be subjected to an electromagnetic rab seal4-50/d10 force that will have the effect of displacing the conductor. This will be the beginning of an elementary electric motor. An electric motor can be defined as a device that transforms electrical energy into another form of energy or that transforms electrical energy with certain characteristics into another form of energy with other characteristics.
