Development of Children and Adolescents, variable frequency power supply was not available this meant constant speed operation at fixed frequency. There are drive applications, where constant speed is desired or where the reactive power that can be generated with line-connected synchronous motors is an important feature. These are, apart

Vertrauen, Misstrauen und Medienffected the operation of the machine and the associated equipment. Also, the specifications for a mechanical power supply are normally not met by just one type of electrical drive and the variety of applications can be bewildering. In this chapter the problems of applying controlled electrical drive

Its main advantage is the elimination of all sliding contacts, resulting in an exceedingly simple and rugged construction. Induction machines are built in a variety of designs with ratings from a few watts to many megawatts.

Variable Frequency Synchronous Motor Drives, machine is very well suited for this duty; it is, in fact, the only one that could be used at a power level of, possibly, several hundred MW. Problems with large synchronous motors operating on a constant frequency supply may be caused by the inherent oscillatory response and the required start-up
