machines, we shall visualize three armature terminals connected to a three-phase power system. This system, in turn, is energized by one or more generators whose function it is to supply the entire load, including “ our” motor, with the electric power it requires, at substantially constant values of

https://doi.org/10.1007/978-3-663-08535-5. They are discussed in two separate chapters because many of their problems of operation are different. Nevertheless, much of what was learned in the previous chapter (on motors) is also valid for generators, and some of the contents of this chapter are equally applicable to motors.

The advocates of a-c systems, lead by innovators like Tesla,* were opposed by no less a giant of the engineering world than Edison, ? who had pioneered the first (d-c) system. Even though the advantages of high-voltage power transmission and

But the two-phase servomotor to be studied in Chapter 16 operates with unbalanced supply voltages, and as far as the single-phase motor of Chapter 17 is concerned,
