How Does a 3-Phase AC Electric Motor Work?

When I think about who invented the 3-phase electric motor, I think of Mikhail Dolivo-Dobrovolsky. However, the 3-phase power evolved out of electric motor development done by Galileo Ferraris and Nikola Tesla independently of each other. In 1885, Italian physicist Galileo Ferraris was responsible for experimenting with different types of asynchronous electric motors. In his […]

The Importance of Dyno Testing

What is Dyno Testing? Dynamometer testing, more commonly known as dyno testing, is a type of motor load test. It detects issues with motors that only surface while under load and ensures that all the electrical properties of a rebuilt motor are correct. This can only be confirmed by putting a minimum of 30-50% load […]
