Chapter 1
Electric motors—The basics
Abstract
Non-specialist readers wishing to learn the essence of how and why motors work will find answers in this chapter. We discuss how to quantify magnetic effects, explain how force and torque are generated, and show that the elegant energy-converting process can be predicted using a simple equivalent circuit. The key factors that underpin the operation of all types of motor emerge, and we conclude by identifying the simple design parameters that determine the relationship between rotor volume and torque.
