Many of these machines require an electric motor for its operation. An electric motor is an essential component to help transform electrical energy into efficient mechanical energy. Normally, motors function through the connection of winding currents for force and the magnetic field. There are motors for every kind of machine. However, there will be times when you should replace the motors and when you need to do so there are specifics you need to know in order to find a replacement. Motor are used in diverse applications. Many industries use them in pumps, fans and blowers, machine tools, power tools, household appliances, and disk drives. Power sources may also differ depending upon country and size of the motor used— generators, inverters, AC (alternating current sources from power grids), and DC (direct current from rectifiers, motor vehicles, or batteries). Electric watches are usually powered by batteries because they have small motors. Ship propellers, pump storage, and pipeline compression require very large electric motors that reach up to 100 megawatts. Motors can be categorized for internal construction, type of motion, and application type among others. Loudspeakers (transducers) and magnetic solenoids (actuators) change electricity into movement, but they do not produce mechanical power that can be used.
