Synchronous Generators (Part 1 of 2)

This video, published by Columbia Gorge Community College, is the first part of a two part lecture on electrically excited synchronous generators in the unloaded condition. During the lecture, presenter Jim Pytel covers the theory behind the construction and operation of synchronous generators. In this video, Pytel discusses the difference between asynchronous/induction generators and synchronous generators, the construction of a synchronous machine in the motor and generator modes, and the role of a prime mover in a generator. Also covered are four electrical output properties: phase sequence, phase shift, frequency, and voltage magnitude.

This video runs 12:15 minutes in length. The second part of the lecture is available to view separately.
