Synchronous Motors (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 motors. The lecture covers synchronous motor construction and theory of operation along with the electrical and mechanical properties of synchronous motors. At the start of the video, presenter Jim Pytel provides background on synchronous motors, discussing the synchronous and induction split in three phase alternating current (AC) motors, and the difference between electrically excited synchronous motors and permanent magnet synchronous motors. Then, Pytel covers the operation and advantages of electrically excited synchronous motors, pull out torque, and "how varying rotor field current changes pull out torque and reactive power consumption during steady state operation."

This video runs 13:27 minutes in length. The second part of the lecture is available to view separately.
