Motors are artifacts whose main purpose is to provide enough energy to a set of parts so that they function properly and the machine they comprise can carry out its activities. Normally, these work with some type of fuel, which can be natural or industrially processed and use the conversion of energy into another type of energy with much more possibilities of being used. Nowadays, the motor is one of the most used inventions, since most of the objects that the human being has created need that impulse that makes it work.

Normally, this term is used specifically for those creations that generate mechanical energy almost immediately. However, machines capable of driving the creation of energy, such as hydroelectric plants, wind turbines and reactors, are usually called engines; This use is considered incorrect due to the activities intended for the final product. This word, likewise, refers to those individuals or entities that are an important part of the functioning of an organism; It is also part of computer jargon, where it is known for encompassing the process of designing a video game or programs that help the operation of a computer.

Engines can be created from various perspectives of operation, so there are many types. Among them are: the electric motor (electricity is the source of operation), the thermal engine (heat energy is the main source of force), the internal combustion engine (chemicals are used, which are converted into energy) and the external combustion engine (the chemical substance is transformed into a different one). Each engine has a series of characteristics, which determine if the functionality will be the desired one; these consist of performance, rated speed, power, torque and stability.
