DESIGN OF SYNCHRONOUS MACHINE

6.1 Introduction

Synchronous machines are AC machines having the field circuit excited by external DC source and the armature circuit with three phase balanced winding exited by an AC source. The armature circuit forms the stator of the synchronous machine and the field circuit constitutes the rotor of the machine. However, for low power synchronous machines, the arrangement similar to DC machine can also be used with the field on the stator side and the armature on the rotor side.

6.2 Types of Synchronous Machine

Synchronous machines, in general, are classified as shown in Fig. 6.1.
