The History of the Electric Motor
Electric motors have become an essential part of our daily lives. They power everything from household appliances to industrial machinery. But when was the electric motor invented? In this article, we will explore the brief history of electric motors and their development over time.
The Invention of the Electric Motor
The first electric motor was invented by British scientist Michael Faraday in 1821. Faraday discovered that by passing a current through a coil of wire, he could create a magnetic field that would cause a nearby magnet to rotate. This discovery laid the foundation for the development of the modern electric motor.
However, it wasn’t until the mid-19th century that practical electric motors were developed. American inventor Thomas Davenport is credited with building the first practical battery-powered electric motor in 1834. Davenport’s motor used a direct current (DC) power source and was used to power a small machine – a printing press.
Development of Electric Motors
Despite Davenport’s great discovery, electric motors were not used on a commercial level for another 50 years. In the late 1800s, the development of efficient electric motors accelerated, thanks to inventors such as Nikola Tesla and Thomas Edison. Tesla’s alternating current (AC) motor invention revolutionized the industry, making it possible to transmit electricity over long distances.
Edison, on the other hand, focused on developing more efficient DC motors. Edison’s motors were used in various applications, from powering streetcars to providing electricity to homes and businesses. Learn more about AC vs DC motors here.
Modern Electric Motors
Today, electric motors are used in an even wider range of applications, from powered wheelchairs and stairlifts to industrial automation, transport and solar panels. The development of new materials and technologies has helped to make electric motors more efficient, powerful, and reliable than ever before.

The electric motor has a long and storied history dating back to the early 19th century. While early electric motors were relatively simple and inefficient, advances in technology and design have helped to make them a critical component in many modern technologies. Today, electric motors are used in a wide range of applications, from transportation to renewable energy systems, and their importance is only likely to grow in the years to come.
