Electric motor

An electric motor uses electrical energy to produce mechanical energy. The reverse process, that of using mechanical energy to produce electrical energy, is accomplished by a generator or dynamo. Traction motors used on locomotives and some electric and hybrid automobiles often perform both tasks if the vehicle is equipped with dynamic brakes. Electric motors are found in household appliances such as fans, refrigerators, washing machines, pool pumps, floor vacuums, clothes dryers, hair dryers, forced air home furnaces, computers requiring cooling, many DVR recorders, attic fans, range hoods, bathroom fans, boot dryers, pellet stoves, many electric heaters, heat guns, and fan-forced ovens. They are also found in many other devices such as computer equipment, in its disk drives, printers, and fans; and in some sound and video playing and recording equipment as DVD/CD players and recorders, tape players and recorders, and record players. Electric motors are also found in several kinds of toys such as some kinds of vehicles, fans, cool water mist fans, blow torches, pencil sharpeners, fan-forced ovens, and robotic toys.
