Development of a High Efficiency Induction Motor: With ever-increasing energy cost the life-time operating cost of an induction motor can be traded against a high efficiency and high capital cost induction motors. With rising demand…
Inverted Induction Motor: In a wound rotor induction machine the three-phase supply can be given to the rotor windings through the slip rings and the stator terminals can be shorted (see Fig. 9.68). Such a…
Dynamic Modelling of Induction Motor: In general, the mechanical time-constant for any machine is much larger than the electrical time constant. Therefore, the Dynamic Modelling of Induction Motor can be simplified by neglecting the electrical…
Isolated Induction Generator: An Induction Machine can also work as a generator even if external power supply not available and it is called Isolated Induction Generator. An Isolated Induction Generator feeding a load is shown…
Induction Generator Transmission Line Diagram: An induction generator is asynchronous in nature because of which it is commonly used as windmill generator as a windmill runs at non-fixed speed. These are used in remote areas…
Standard Types of Squirrel Cage Motors: To cater to the different starting and running requirements of a various industrial applications, several Standard Types of Squirrel Cage Motors are available in the market. The torque-speed characteristics…
Double Cage Rotor Induction Motor: A rotor design, which though more expensive gives still better starting, and running performances than the deep-bar design, is the Double Cage Rotor Induction Motor. The double squirrel cage induction…
Deep Bar Rotor Induction Motor: In this type of Deep Bar Rotor Induction Motor construction, bars of narrow width are laid down in deep semi-enclosed slots as shown in Fig. 9.52. The magnetic leakage flux…
Speed Control of Induction Motor: Stepless control of speed of induction motors cannot be carried out as efficiently and inexpensively as for dc motors. Various methods of Speed Control of Induction Motor can be visualized…
Crawling and Cogging in Induction Motor: Crawling and Cogging in Induction Motor - A squirrel-cage rotor may exhibit a peculiar behavior in starting for certain relationships between the number of poles and the stator and…
