Energy DC motors: Why are they still used? The reasons

Feb 04, 2010 There are two reasons. The first can be summed up in two words: installed base. Let's remember that the DC motor was the primary variable-speed shaft-turning device since 1888. When AC inverters and AC motors started to replace DC in machines can be debated, so let’s put a stake in the ground and call it 1987.
