Rotating machinery explained - DC motors : identify the armature and fields - Bergwall Productions (New York Bergwall Productions, 1982)
Notes This series of five Color/Sound films on direct Current Notes This series of five Color/Sound f Motors is the foundation for the understanding of the files Notes This series of five Color/Sound f of electrical rotating machinery and the controls used to Notes This series of five Color/Sound f regulated them. Starting with a simple DC motor, the Notes This series of five Color/Sound f principles of operation are described and expanded to explain Notes This series of five Color/Sound f the connections and uses of shunt, series, and compound Notes This series of five Color/Sound f motors. The method used to identify the field and armature Notes This series of five Color/Sound f terminals of a motor is demostrated and the Countr EMF is Notes This series of five Color/Sound f measured. Notes This series of five Color/Sound f The titles of the individual films are: 1. Principles of Notes This series of five Color/Sound f operation - Part 1, 2. Principles of Operation - Part 2, 3. Notes This series of five Color/Sound f Identify the armature and files, 4. Measuring motor Notes This series of five Color/Sound f resistance: voltmeter-ammeter method, 5. Counter Notes This series of five Color/Sound f electromotive force.
