### Design of Synchronous Machines Introduction

2016-7-4 Synchronous machines are AC machines that have a field circuit supplied by an external DC source. Synchronous machines are having two major parts namely stationary part stator and a rotating field system called rotor. In a synchronous generator, a DC current is applied to the rotor winding producing a rotor magnetic field.

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.
