Electric motor is an electrical and mechanical (electromechanical) device that converts

electrical energy into mechanical energy.

Most electric motors operate through the interaction ofmagnetic fields and current-carryingconductors to generate force. The reverse process, producing electrical energy from mechanical

energy, is done by generators such as an alternatoror a dynamo. Some electric motors can also

be used as generators, for example, a traction motoron a vehicle may perform both tasks.Electric motors and generators are commonly referred to as electric machines.Electric motor have 8 important and important parts of it. Centrifugal switch is an electric switch

that operates using the centrifugal force created from a rotating shaft. Most commonly that of an

electric motor or gasoline engine. Statoris the stationary part of a rotor system or a siren, foundin an Electric motor.Rotoris the non-stationary part of a rotary electric motor, electric generator

or alternator. It rotates causes the wires and magnetic field of the motor are arranged. Drum

motor(or Drive pulley) is a geared motor drive enclosed within a steel shell providing a single

component driving pulley for conveyor belts. Cooling fan is a machine used to create flow withina fluid, typically a gas such as air to avoid overheating its inner parts.Power supply is a device

that supplies electric power to an electrical load to electric power converters from electrical

energy to another form of energy (mechanical, chemical, solar). Terminal box is an enclosurewhich includes, mounts, and protects one or more terminal boards, it may include a cover and

such accessories as mounting hardware, brackets, locks, and conduit fittings. Bearingis a

machine element that constrains relative motion between moving parts to only the desired

motion.Ampre's force law, was created byAndr-dMarie Ampre in 1820. Electric motors of increasing

efficiency were constructed from 1821 through the end of the 19th century, but commercial

exploitation of electric motors on a large scale required efficient electrical generators andelectrical distribution networks. The first commercially successful motors were made around

1873 byZnobe Gramme

Electric motors are found in applications as diverse as industrial fans, blowers and pumps,

machine tools and household appliances. They may be powered by direct current or a batterypowered portable device or motor vehicle, or by alternating current from a central electrical

distribution grid orinverter. Small motors may be found in electric wristwatches. Medium-size

motors of highly standardized dimensions and characteristics provide convenient mechanicalpower for industrial uses. The very largest electric motors are used for propulsion of ships,

pipeline compressors, and water pumps with ratings in the millions ofwatts. Electric motors may

be classified by the source of electric power, by their internal construction, by their application,or by the type of motion they give.

Some devices convert electricity into motion but do not generate usable mechanical power as a

primary objective, and so are not generally referred to as electric motors. For example, magneticsolenoids and loudspeakers are usually described as actuators and transducers

respectively,

instead of motors. Some electric motors are used to produce torque or force.
