Development of a High Efficiency Induction Motor

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 for high efficiency or energy efficient induction motors, designers and manufacturers are stepping up their production of such motors. Some …

Inverted Induction Motor

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 Rotor Fed Induction Machine is also called an Inverted Induction Motor. The three-phase rotor current will generate a rotating field …

Isolated Induction Generator

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 in Fig. 9.61. The delta-connected capacitors across the generator terminals provide the magnetizing current necessary to excite the isolated generator. …
