This is because in 1802 Petrov described not only the electric arc, but also its uses for melting and welding metals, for reduction of metal oxides, which allowed extraction of metals from ores, and in lighting. Earlier in 1801, he discovered the electric arc, although the Russian scientific community believes that it was first discovered by Vasily Vladimirovich Petrov. After the battery was built, numerous discoveries that used it followed in chemistry and physics.įor example, in 1807 a British scientist Humphry Davy was studying the electrolysis of molten sodium and potassium hydroxides, and during these studies produced sodium and potassium metals. It was a truly incredible invention, later used by many researchers in their work because it allowed to encourage movement of electric charges in conductors, thus generating electric current. In 1800 Alessandro Volta built a chemical battery, which was later called the voltaic pile.

This 12.5 kW diesel generator displayed in the Military Communications and Electronics Museum in Kingston, Ontario, was used at isolated northern stations to power large radio transmitters and receivers In fact, drones are so popular that many large corporations are currently lobbying for air space allocation for delivery drones. There are so many self-piloted drones in use today - they are also powered with electric motors. Very soon the airplane Solar Impulse 2 will complete a trip around the world (the article was written in November 2015).
We can find them labor away on the surface of the Earth, underground, on the surface of the water, underwater, and even in the air. The electric motors of today are present not only on Earth but also in space, such as in the Mars science laboratory "Curiosity". Besides, they have also used to power all kinds of industrial and research robots. They also provide numerous other invaluable services as part of various woodworking, metalworking, stone working, and other tools and machines, power tools, and mechanisms.Įlectric motors are even used in powered exoskeletons for people with disabilities and veterans. They bring water all the way up to the top floors of skyscrapers, operate fountains, remove water from mines and wells, roll steel, and are built into cranes to lift heavy items in the construction industry. The hope is that the issue of getting the (electric) starter running in the cold and other petrol- and diesel-related problems can be forever forgotten once you switch to an electric car.Įlectric motors are all around us: they move our elevators up and down and push our subway trains, electric multiple units, trams, trolleybuses, and high-speed trains. Some of us have dreamt of a Tesla electric car when trying to start our car at −40 ☌ temperatures. Some men’s wish list is quite humble: for those who do not enjoy handiwork, it may include an electric drill at most. Of course, an air conditioner is very important as well, but for those who cannot afford it, a fan will do the job. Those who love gourmet cooking also enjoy owning an electric meat grinder and a bread maker. Also important are microwaves, hairdryers, coffee grinders, mixers, and blenders. No modern person can imagine their household without a fridge, a vacuum cleaner, or a washing machine. They are our primary helpers and do heavy-duty work in the industry, the transportation sphere, and in everyday life. We are surrounded by electric motors and generators. A universal motor that can operate on both AC and DC power is usually used in cordless drills
