Steady State Induction Machine Drives

5.1 Introduction

In this chapter, we will introduce induction machine drive systems that are based on observations drawn from steady state behavior of the machine. To do so, we need to closely examine the steady state model of an induction machine particularly with regard to its torque–speed characteristics.

This chapter will only focus on the fundamental aspects of the drive systems discussed and will not include the actual circuits that need to be employed to realize them. Ideal voltage/current sources with full controllability will be assumed in the development of drives. Once the fundamentals are established, understanding the circuitry that is used to implement our ideal controlled sources ...
