Electrical machine dynamics

Abstract

In this chapter, we shall look at the dynamic performance of some typical machines using approximate methods of solution. The analytical technique developed in the previous chapter leads to more exact solutions and will be used later, in the form of generalised machine theory. There is, however, the danger that by formulating equations in a ‘mechanical manner’ and solving them by using a digital computer, one may lose sight of the physical processes that are involved. The approximate methods often help us to obtain a physical insight into the behaviour of the systems.
