Three Phase Induction Motors Introduction The three-phase induction motors are the most widely used electric motors in industry. They run at essentially constant speed from no-load to full-load. However, the speed is frequency dependent and consequently these motors are
Large induction motors form the backbone of cement, mining, chemical, power, oil and gas industries driving fans, kiln, compressors, pumps and other critical applications in manufacturing processes. Unlike small induction motors, most
Synchronous vs Induction Motors • Synchronous Motors – Turn at exactly the same speed as the rotating magnetic field. – 3600 rpm, 1800 rpm, etc. • Induction Motors – Turn at less than synchronous speed under load. – 3450 rpm, 1740 rpm, etc.

There are two general types of polyphase induction motors: the squirrel-cage type and the wound-rotor machine. Both motors have an armature or stator structure similar to that of the alternating current generator, consisting
AC induction motors, which contain a cage, are very popular in variable-speed drives. They are simple, rugged, inexpensive and available at all power ratings. Progress in the field of power electronics and microelectronics enables the application of
Induction motors have five major components of loss; Iron loss, Copper loss, Frictional loss, Windage loss and Sound loss. All these losses add up to the total loss of the induction motor.
