Wound Rotor Induction Motors (Part 2 of 2)

This video, published by Columbia Gorge Community College, is the second part of a two part lecture on wound rotor induction motors. The lecture covers "the construction and theory of operation of wound rotor induction motors as well as examine their mechanical and electrical properties while in operation." In this video, presenter Jim Pytel discusses motor resistance, variable resisters, and their effect on the shape of the speed torque curve. Pytel then compares no resistance, low resistance, and high resistance wound rotor induction motor configurations, analyzing the speed torque curve, mechanical power, inrush current, real power, and efficiency of each.

This video runs 11:37 minutes in length. The first part of the lecture is available to view separately
