Due to the need to preserve the ozone layer from the emission of polluting gases, the electric motors are inserted without automotive vehicles with the function of saving energy, conserving the environment. Polluting gases, such as carbon dioxide from exhaust fumes from factory smokestacks, have a great potential for ozone depletion. The operation of the electric motors is linked to the principles of electromagnetism, in which the conductors in a magnetic field crossed by electric current, can undergo the action of a mechanical force called torque.


Electric motors are devices whose function is to convert electrical energy into mechanical energy. Electric motors have the ability to reconcile ease of transportation, economy, cleanliness and simplicity of command. They are machines with simplified projection and great possibility of adaptation to different types of load. Generally, engines are not capable of producing energy, converting other types of energy into mechanical energy so that they can operate. According to Lavoisier, in nature nothing is lost and nothing is created everything is transformed. This factor states that nothing can be created without a reference, having to transform something already existing.
