Operating an AC Three-Phase Induction Motor
This Demonstration illustrates the operation of an induction motor. You can create a voltage imbalance or a phase shift in the three-phase source. This will result in a change in speed of the rotor that represents a change in developed torque.



AC Induction Motor How it works
This is the basic principle of how induction motors work. There is a lot more to say about motors, as starter winding with steady capacitor, multiple pole windings, three phases motor, etc etc, but the basic theory is this one !



AC Induction Motor
Induction MotorAn induction motor is an alternating current-based electric motor, where the rotor's rotation frequency does not equal to the rotation frequency of the magnetic field generated by the stator's winding. The induction motor is in fact the most common type of electric motors. The induction motor has a stator and a rotor divided by air space. Its active elements are the winding and the magnetic core; the rest of the parts are structural designed to ensure the required hardness, rigidity, cooling and rotation capability. The motors used in household appliances are usually built with the help of a phase rotor and stator. But there also exist motors with a square-cage rotor, where the current at launch exceeds the rated current by 4-7 times.



Control of Induction Motors (Engineering) [Kindle Edition]
This book is a comprehensive reference source for practicing engineers and students specializing in electric power engineering and industrial electronics. It will illustrate the state of the art in induction motors. Beginning with characteristics and basic dynamic models of induction motors, and progressing to low- and high- performance drive systems. The book will be rich in useful information, without an excessive mathematical burden. Computer simulations resulting in mock oscillograms of physical quantities are used for illustration of basic control concepts.
