AuthorWhen Was the Electric Motor Invented
The electric motor was invented in the early 19th century. The concept of electromagnetic rotation was first demonstrated by Michael Faraday in 1821, and the first practical electric motor was built by Thomas Davenport in 1834. Davenport’s motor was a simple, small-scale device, but it marked the beginning of the development of electric motors that would go on to power a wide range of machinery and appliances, revolutionizing various industries and daily life.

The Rise of Practical Electric Motors
1828: Ányos Jedlik
Hungarian engineer Ányos Jedlik is credited with building one of the earliest known electric motors in 1828. His design used a simple ring made of wire to create a rotating magnetic field.
1832: William Sturgeon
Englishman William Sturgeon developed the first practical electromagnet in 1832. This innovation was crucial for the advancement of electric motor technology.
1834: Thomas Davenport
American blacksmith Thomas Davenport is often regarded as the inventor of the first DC electric motor. His design used a rotating armature and magnets.
The Battle of Patents
1873: Zenobe Gramme
Belgian engineer Zenobe Gramme’s dynamo, invented in 1873, was a significant breakthrough. It efficiently converted mechanical power into electrical power and vice versa, paving the way for practical applications.
1888: Nikola Tesla
The late 19th century saw a fierce battle of patents between inventors. Nikola Tesla, the Serbian-American inventor, played a pivotal role with his AC (alternating current) motor, patented in 1888.
Modern Electric Motors
20th Century Advancements
The 20th century witnessed significant advancements in electric motor technology. These motors became smaller, more efficient, and applicable in a wide range of industries.
