It is important to note that most electrical machines perform their many functions through the interaction between electromagnetic fields, although engines based on different electromechanical phenomena can be found. It is possible to affirm that the fundamental principle in which the electromagnetic motors refer is that there is a mechanical force in the whole wire, at the moment in which it is conducting the electric current immersed in a magnetic field. The electric motor consists of a component capable of transforming electrical energy into mechanical energy.
Of all the types of machines found, it is seen as the most used for having the advantages of electric energy, such as hygiene, transport and simplicity of control, considering its simplified projection, great economy and high versatility of adaptation to different loads with optimized yields. In the case of the reverse task, capable of converting the mechanical movement into electric energy, it is generated by a generator or a dynamo acme CE010100. In the great majority, the two components can differ only in their application and details of projection. Traction engines found on locomotives, for example, fulfill both functions if the locomotive is equipped with dynamic brakes.
