In what year was the electric motor invented and who invented the motor

Germany. Jacobi.

Invented the DC engine.

Yugoslav-American.

Tesla. The AC motor was invented.

In 1821, the British scientist Faraday was the first to prove that electricity could be converted into rotational motion. The first person to make an electric motor is said to be Jacobi in Germany. He became a simple device around 1834:

In the middle of the two U-shaped electromagnets, a six-arm wheel is installed, and each arm is equipped with two rod-shaped magnets. After the power is applied, there is mutual attraction and repulsion between the rod magnet and the U-shaped magnet.

Drive the wheel axle to rotate. Later, Jacobi made a large installation. Installed on a dinghy, powered by 320 denier batteries, the dinghy made its first voyage on the Elbe in 1838 at a speed of only kilometers per hour, and at the same time, Davenport in the United States also succeeded in producing an electric motor to drive a printing press, and printed the American telegraph sentence "Electromagnetic and Mechanical Information".

However, these two types of motors do not have much commercial value, and the cost of using batteries as a power source is too high and impractical.

Until the first practical DC engine came out.

Electric motors are widely used. In 1870, the Belgian engineer Graham invented the DC generator, which is similar to the electric motor in design. Later, Gramm proved that when an electric current is fed into a DC engine, its rotor rotates like an electric motor.

As a result, this Gramm-type electric motor was manufactured in large quantities. Efficiency is also improving. At the same time, Germany's Siemens took on the task of building better generators and began to work on vehicles powered by electric motors, so Siemens made the world tram.

In 1879, at the Berlin Industrial Exhibition, Siemens' non-smoking tram won a round of applause from the audience. The Siemens electric locomotive was only 3 horsepower at that time, and the electric locomotive tested by Edison, the American inventor, has reached 12-15 horsepower. However, at that time, all motors were DC motors, which were limited to driving trams.

In 1888, the Yugoslav-born American inventor Tesla invented the alternating current electric motor. It is made according to the principle of electromagnetic induction, also known as induction motor, this motor has a simple structure, uses alternating current, no rectification, no spark, so it is widely used in industrial household appliances, AC motors are usually powered by three-phase AC.

The electric motor was invented by Michael Faraday.

Faraday made his first major invention of electricity, and on October 28, 1831 he succeeded in inventing a simple device, in fact Faraday invented the first electric motor, the first device to use electricity to move an object in motion.

2. Michael Faraday (1791 A.D. 1867), a world-famous self-taught scientist, British physicist, chemist, and inventor, the inventor of generators and electric motors.

The electric motor was invented by Michael Faraday.

Michael Faraday (September 22, 1791 – August 25, 1867) was an English physicist, chemist, and self-taught scientist.

Michael Faraday was a student and assistant of the famous British chemist Humphrey Davy, whose discoveries laid the foundation for electromagnetism and were pioneered by James Clark Maxwell. On October 17, 1831, Faraday discovered the phenomenon of electromagnetic induction for the first time, and then obtained a method for generating alternating current. On October 28, 1831, Faraday invented the disc generator, the first generator created by man.

On August 25, 1867, Faraday died at the age of 76.

Character influence

Michael Faraday gave a number of successful lectures on physics and chemistry at the Royal Academy, entitled "The History of Candle Chemistry"; This speech became the origin of the "Royal Academy Christmas Speech", which bears the name of Faraday.

Faraday's ** was printed on the $20 banknote from 1991 to 2001. The former British laboratory in Antarctica: the Faraday Gas Matching Waiting Research Station bears his name, and the capacitors are named after him.

In addition, the amount of electricity contained in one mole of electrons (about 96,485 coulombs) is also known as Faraday's constant, and his unparalleled contribution to electricity is remembered. Faraday's law of electromagnetic induction states that a magnetic flux that changes over time creates an electromotive force.

Motor. of inventions.

After Oster discovered "electromagnetism", he regretted that he could not use it to invent a device that can be continuously rotated by electricity-electric circular motion machine.

On September 3, 1821, the British physicist and chemist Faraday produced the prototype of the first and most primitive electric motor in human history when he repeated Oster's experiment of "electro-magnetism" - a device in which a magnet (or fixed wire) fixed in a mercury cup rotates continuously around a fixed energized wire (or fixed magnet).

Brief History. Gramme (zénobe théophile) Belgian French inventor. Born on April 4, 1826 in Geebert, Belgium; He died on 20 January 1901 in Boisgo Lombert, Hauts-de-Seine, France.

Gramm was born in Belgium to a family of civil servants. His grades in school were really poor. In all fairness, it should be said that he has always been a big boss all his life.

However, his hands are very dexterous, and he is indeed a master at fiddling with electrical equipment. In 1856, Graham came to Paris and has lived in the Paris region ever since. He got a job at a company that specialized in the manufacture of electrical equipment.

In 1867, he built an improved alternator; In 1869, he built a direct current generator. Although Faraday and Henry had already established the feasibility of building a generator in principle, the generators they created were only experimental devices. The real power generation equipment that could be used in industrial production was realized in the hands of Gramm.

The power industry was built on these two generators in Gramm.

Faraday discovered the law of electromagnetic induction, the emergence of electromagnetic induction, and all applications were opened: motors, generators, automobiles, trains, horns, aviation, industry, magnetic energy, machinery, engines, mobile phones, computers, storage, chips, electrical appliances, transmitters, controllers, contactors, relays, magnetic cards, **, recording ......It's all about electromagnetic induction.
