Summary
The Gramme machine or Gramme dynamo, an <a href="https://en.wikipedia.org/wiki/electrical_generator" class="extiw" title="wikipedia:electrical generator">electrical generator</a> designed by Belgian inventor Zénobe Gramme in 1871. It was the first machine to be used industrially to generate power. His innovation was to use many armature windings, wound on a doughnut shaped armature, and switched with a many segmented commutator, to smooth the output waveform, producing nearly constant DC power. This shows a hand cranked model from the 1870s designed for use in laboratories, it's output was equivalent to "eight ordinary Bunsen elements [batteries]". It used laminated permanent magnets invented by Jamin.
