An Electric Motor is an converts electrical energy into mechanical energy. The opposite of this is the conversion of mechanical energy into electric power and is made by an electric generator and motors have much in common. Most Electric Motor act through the interaction between a magnetic field and the winding currents to generate power. In some applications such as regenerative braking with traction engines in the transport industry, electric motors can also be used in reverse as generators to convert mechanical energy into electrical energy.
The Electric Motor is located in industrial and pumps, machine tools devices, power tools and drives can be powered by direct current sources such as motor vehicle batteries or rectifiers or alternating current sources from the switches or generators in the electrical network. Electric Motor is available in electrical clocks the general-purpose with highly standardized dimensions and properties provides mechanical power suitable for industrial use. The largest Electric Motor is used for propulsion of the ship the compression of the pipe and pumping storage applications with a rating of 100-megawatts can be classified by type of electrical power source type of internal design of motion effect.
Electric Motors are used to produce a linear or rotating power and should be distinguished from devices such as magnetic solenoids and loudspeakers that convert electricity to motion but do not generate useful mechanical forces, which are actuators and sensors. In an Electric Motor, the movable part is the rotor that rotates the shaft to deliver the mechanical force. The rotor usually has conductive posts in which bear currents interact with the magnet field of the stator to generate forces that rotate the axis.
