Electric Motors – What Are They & How Do They Work?

December 4th, 2014 (No Comments)

An electric motor is a machine which is powered by electricity and converts it into a mechanical force. There are a number of devices which do this such as a loudspeaker or industrial fan for example, but the electric motor specifically generates ROTARY motion. This rotary motion can drive a shaft on which other mechanical elements can be driven. This motion can then be applied to drive the machinery behind things as small as a wristwatch to gigantic ship propulsion propellers. Electric motors are quickly replacing the more traditional hydraulic cylinders in airplanes and also in some military equipment.
