More information

In 1873 he and Hippolyte Fontaine accidentally discovered that the device was reversible and would spin when connected to any DC power supply. The Gramme machine was the first usefully powerful electrical motor that was successful industrially. Before Gramme's inventions, electric motors attained only low power and were mainly used as toys or laboratory curiosities. In 1875, Nikola Tesla observed a Gramme machine at the Graz University of Technology. He conceived the idea of using it for alternating current but was unable to develop the idea at this time.
