Energy Efficiency in Electric Motors

Electric motors are electrical machines that convert electrical energy into mechanical energy to perform useful work. In general, electric motors have three main parts: a rotor, a stator, and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually so long as it receives a steady flow of electric current. These main parts also comprise other parts that transmit electric current (windings, etc.), parts that transmit magnetic flux, and parts of construction (bearings, etc.). In order to increase energy efficiency in electric motor systems, attention should be paid to the following such as motor selection, power quality, motor control systems (variable speed drive), power transmission systems equipment (fan, pump, compressor, etc.), system and design, process type, and maintenance are all the topics that need to be considered in order to increase energy efficiency in systems using electric motors.
