Electric Motors

Many people use the electric motor every day, but they don’t know they are doing it or they just don’t think about it. The truth is, this device changed the face of industry and made all sorts of useful, essential appliances and inventions come to live. Our lives are so much more comfortable because the electric motor exists.

Back in 1833, Thomas Davenport invented the motor engine, which is a device that converts electrical energy into mechanical energy. Ever since it’s been constantly improved and used in many innovative inventions. An electric motor is made up of several essential parts: the armature, also called the rotor, the axle, the commutator, of course, the brushes, the field magnet and the power source, which can be DC or AC.

The electric motor works as it follows: the electrical current that is generated goes through a rotating wire loop, placed within what is generally called a magnetic field. It’s this loop that redirects the electric energy towards the other various components so that mechanical power is produced. The electric energy that the electric motor used is stored in a battery. Batteries are usually rechargeable and they do not pollute the environment while they work. Not only do they release electrons in the electric motor but they also manage to collect the newly generated electrons that result that result as a consequence of the electric motor being at work. Electric motors are able to produce alternating currents and direct currents. Small appliances usually use the DC while big motors and appliances use AC.

The electric motor is very useful and consequently largely spread: statistics show that in the U.S. around 19% of the energy sources are powered by electric motors or systems based on electric motors. This means that more than half the energy that goes to the population is generated through such systems. You might be familiar to the electric motor systems used by vehicles, industrial machines and home appliances.
