Although the earliest practical DC motor was built by Moritz Jacobi in 1834, it was over the next 40 years that men like Thomas Davenport, Emil Stohrer and George Westinghouse brought DC machines into industrial use. 
It’s inspiring to realize that work-ing DC motors have been around for over 160 years. For the past century, DC machines over thirty or forty kW have been cooled in the same manner – by mounting a squirrel cage blower directly over the commutator.
