With the increasing focus on communications and computing the humble electric motor is often overlooked. It has been estimated that in excess of one third of all electricity generated is converted to mechanical energy by electric motors. While a large part of this is by ac induction motors, an increasing amount is by smaller lower-voltage motors driven from a dc supply. The average PC for example will have about ten dc motors to move air, and drive hard disks and CDs. When printers, scanners, and game controllers are taken into account this number can double.
