Facts you need to know about un motor

Here's my thoughts about UN motor / an motor

An electric motor is a machine, the electrical energy into mechanical energy by electromagnetic interactions. Some electric motors are reversible, mechanical energy into electrical energy to run the generator to change. Traction motors used on locomotives often perform both tasks if they are equipped with brakes regeneration.

They are often used in industrial facilities, commercial and private. You can operate to produce electricity or batteries connected. Thus began the car used in hybrid vehicles in order to exploit.

An electric motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy, is accomplished by a generator or dynamo. Many types of electric motors can be run as generators, and vice verse. For example a starter/generator for a gas turbine or Traction motors used on vehicles often perform both tasks.


Electric motors are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives. They may be powered by direct current (for example a battery powered portable device or motor vehicle), or by alternating current from a central electrical distribution grid. The smallest motors may be found in electric wristwatches. Medium-size motors of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses. The very largest electric motors are used for propulsion of large ships, and for such purposes as pipeline compressors, with ratings in the millions of watts. 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.

The physical principle of production of mechanical force by the interactions of an electric current and a magnetic field was known as early as 1821. Electric motors of increasing efficiency were constructed throughout the 19Th century, but commercial exploitation of electric motors on a large scale required efficient electrical generators and electrical distribution networks.

Some devices, such as magnetic solenoids and loudspeakers, although they generate some mechanical power, are not generally referred to as electric motors, and are usually termed actuators and transducers, respectively.
