Abstract
The commutator in a DC machine performs a complex function which we have not attempted to analyse in detail; the performance equations, on the other hand, are relatively simple. With the AC synchronous and induction machines, the situation is reversed. The absence of a commutator simplifies both the structure and the detailed analysis, but the machine equations are more complex and the basic theory is conceptually more difficult. In this chapter we develop some of the principles which are common to all AC machines by considering the magnetic field set up by currents flowing in the windings. It is convenient to start with the AC generator introduced in the previous chapter.
