Electric Motors

An electric motor uses electrical energy to produce mechanical energy, and this is normally achieved by the interaction of magnetic fields and current- carrying conductors. Electric motors can be used for a vast amount of applications and uses, such as machine tools, household appliances, pumps, and computer disc drives, and many other uses. Electric motors can be operated by the direct current from a battery, or an alternating current supplied from a central electrical distribution grid. Small electric motors can be found in electric wristwatches, while more medium sized electric motors can be used for industrial purposes. The largest electric motors, are used to propel large ships and can also be used as pipeline compressors.
