Doubly Fed Induction Motors (Part 2 of 2)

This video, published by Columbia Gorge Community College, is the second part of a two part lecture on doubly fed induction motors. The lecture examines the construction, operation, and different operational modes of doubly fed induction motors. Also discussed is how varying rotor excitation frequency impacts motor rotational speed. In this video, presenter Jim Pytel covers the hypersynchronous mode and walks viewers through a case study demonstrating how the rotational speed of a double fed induction motor responds to different rotor excitation frequencies.

This video runs 21:21 minutes in length. The first part of the lecture is available to view separately
