Abstract :
There can be few types of machine with so diverse an involvement In the development of electrical engineering as the inductor alternator. Simple mechanical design - the rotor need carry no windings - and flexible electrical characteristics have found the machine applications in widely differing fields. It has been used to generate powers ranging from watts to megawatts at frequencies of 20 Hz-200 kHz, and it enjoyed a fast rise to popularity. Its subsequent history, however, has been one of changing fortunes.
