Introduction

It is known that the electric supply used, now a days for commercial as well as domestic purposes, is of alternating type.

Similar to d.c. machines, the a.c. machines associated with alternating voltages, are also classified as generators and motors.

The machines generating a.c. e.m.f. are called alternators or synchronous generators. While the machines accepting input from a.c. supply to produce mechanical output are called synchronous motors. Both these machines work at a specific constant speed called synchronous speed and hence in general called synchronous machines.

All the modem power stations consists of large capacity three phase alternators. In this chapter, the construction, working principle and the e.m.f. equation of three phase alternator is discussed.
