An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
The magnet was made of 18 turns of bare copper wire (insulated wire had not yet been invented). [1] William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnet and the first practical electric motor.
Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [ 3 ] [ 5 ] He invented the commutator . In 1828, Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator , rotor and commutator.
The "whirl" was an electrostatic reaction motor, the earliest of its kind; [1] while the second derives its theoretical importance as the first instance of the application of what came to be called electric convection. Gordon died in Erfurt, Thuringia.
Electromagnetic rotation experiment of Faraday, 1821, the first demonstration of the conversion of electrical energy into motion [48] In 1821, soon after the Danish physicist and chemist Hans Christian Ørsted discovered the phenomenon of electromagnetism, Davy and William Hyde Wollaston tried, but failed, to design an electric motor.

Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. [22] Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his "On Physical Lines of Force" in 1861 and 1862. [23]: 148
In 1999, grandsons, John L. Sprague and Peter Sprague cut the ribbon and started an 1884 Sprague motor at a new exhibit at the Shore Line Trolley Museum, where a permanent exhibit, "Frank J. Sprague: Inventor, Scientist, Engineer", tells the story of the role of the "father of electric traction" and the role of electricity in the growth of cities.
As early as 1834, he developed a battery-powered electric motor, along with his wife Emily Davenport. They used it to operate a small model car on a short section of track, paving the way for the later electrification of streetcars. [2] It is the first attempt to apply electrification to locomotion.
