Characteristics of Electrical Motors

After completing this chapter, students should be able to do the following:

•  Model the characteristics of DC motors and specify their model parameters.

•  Model the characteristics of induction motors and specify their model parameters.

•  Perform transient analysis of electric motors.

•  Perform worst-case analysis of electric motors for parametric variations of model parameters and tolerances.

14.1  INTRODUCTION

The PSpice simulation of power converters can be combined with the equivalent circuit of electrical machines to obtain their control characteristics. The machines can be represented in SPICE by a linear or nonlinear magnetic circuit or in a function or table form. We use linear circuit models ...
