Electric motors are tools to convert electrical energy into mechanical energy. A device that works the other way around, converting mechanical energy into electrical energy is called a generator or dynamo. Electric motors can be found in household appliances such as fans, washing machines, water pumps and vacuum cleaners.
Gearbox Electric motors commonly used in the Industrial world are asynchronous electric motors, with two global standards namely IEC and NEMA. IEC-based asynchronous motors are metric-based (millimeters), whereas an imperial-based NEMA (inch) electric motor, in applications there are units of power in horsepower (hp) and kiloWatt (kW).
