British physicist and chemist Michael Faraday is widely credited with developing the first electric motors in 1821. These early motors were meant to demonstrate the conversion of electrical energy into mechanical energy and they had no practical application. Others consider fellow Englishman William Sturgeon the true inventor of the electric motor. In 1832, Sturgeon developed a motor with a revolutionary new part call the commutator, an electrical switch which can be found in most modern motors.
The modern DC motor was invented by accident in 1873, when Zenobe Gramme connected the dynamo he had previosly invented to a secon similiar unit, then driving it as a motor. The machine was called the Gramme machine and would be the first electric motor that was successful in the industry.
