History
In the United States Patent Office can be found an early description of a drum motor from 1932. The application for this "conveyor roller" is from November 1928 and it was applied by the Pittsburgh subsidiary of the German engineering company Schloemann.
20 years later this very early concept was finally conveyed into an industrial drive. In the early 1950s the Danish inventor and entrepreneur John Kirkegaard designed the first industrial-type drum motor.
