2. ELECTRIC MOTORS25 Bureau of Energy EfficiencySyllabus ELECTRIC MOTORS :Types, Losses in induction MOTORS , motor efficiency, Factors affectingmotor performance, Rewinding and motor replacement issues, Energy saving opportunitieswith energy efficient IntroductionMotors convert electrical energy into mechanical energy by the interaction between the mag-netic fields set up in the stator and rotor windings. Industrial ELECTRIC MOTORS can be broadly clas-sified as induction MOTORS , direct current MOTORS or synchronous MOTORS . All motor types havethe same four operating components: stator (stationary windings), rotor (rotating windings),bearings, and frame (enclosure). motor TypesInduction MotorsInduction MOTORS are the most commonly used prime mover forvarious equipments in industrial applications. In inductionmotors, the induced magnetic field of the stator winding inducesa current in the rotor.
of 2 %. In view of this, for selecting high efficiency motors, the following can be done: a) When purchasing large number of small motors or a large motor, ask for a detailed test cer-tificate. If possible, try to remain present during the tests; This will add cost. b) See that efficiency values are specified without any tolerance
