An old engraving of a magneto-electric device of the mid-1800s. It is from a Victorian book of the 1890s on discoveries and inventions during the 1800s. This particular device has horizontal electro-magnets. It was used for producing power rather than for lighting. It is based on a Gramme machine (Gramme ring, Gramme magneto, or Gramme dynamo), an electrical generator that produces direct current, named after its Belgian inventor, Zénobe Théophile Gramme (1826 –1901). It was built as either a dynamo or a magneto. It was the first generator to produce enough power for industrial use.

It was built as either a dynamo or a magneto. It was the first generator to produce enough power for industrial use. Gramme was the developer of a new induced rotor in form of a wire-wrapped ring (Gramme ring). Although popular in 19th century electrical machines, the Gramme winding principle is no longer used since it makes inefficient use of the conductors.
