In 1820 Andre Ampere Hans, orested discoverd that electric current produce magnatic field M. Faraday try to prove the theory of the Ampere and Orested. 10 years later ,Joeshep H. upgrade the motor based on the Faraday's motor. The major one took place with William Stargen's invention the com mut- ator .In 1873 Zenobe G. accinently linked on the spinning motor. Then he ran it as the motor. Use of motor

\Motoring offenses attract an on spot fine.\An agreement with really a call Milwaukee the new India assurance company limited concurs motors\Motor use at so many place.\A stepper motor can 'rustle' at slow speeds\Electric motors from 55 kw up to 160 kw are available\Motor racing ceased in Europe.The use of motor in house are very important. It even helps to get wind from the fan, computer and so many things. PERSONAL EXPERIENCES ====== An electric motor is an electric machine that converts electrical energy into mechanical energy. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor. In certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and regenerative modes to also produce electrical energy from mechanical energy. Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current sources, such as from batteries, motor vehicles or rectifiers, or by alternating current sources, such as from the power grid, inverters or generators. Small motors may be found in electric wristwatches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings approaching a megawatt. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on. Devices such as magnetic solenoids and loudspeakers that convert electricity into motion but do not generate usable mechanical power are respectively referred to as actuators and transducers. Electric motors are used to produce rotary or linear torque or force.
