Rotating machinery explained - DC motors : Counter electromotive force Bergwall Productions [VHS Tapes].

Notes This series of fove Color.Sound films on Direct Current Notes This series of fove Color.Sound f Motors is the foundation for the understanding of the field Notes This series of fove Color.Sound f of electrical rotating machinery and the controls used to Notes This series of fove Color.Sound f regulate them. Starting with a simple DC motor the principles Notes This series of fove Color.Sound f of operation are described and expanded to explain the Notes This series of fove Color.Sound f connections and uses of shunt, series, and compound motors. Notes This series of fove Color.Sound f The method used to identify the field and armature terminals Notes This series of fove Color.Sound f of a motor is demonstrated and the counter EMF is measured. Notes This series of fove Color.Sound f The titles of the individual films are: 1. Principles of Notes This series of fove Color.Sound f operation - Part 1, 2. Principles of operation - Part 2, Notes This series of fove Color.Sound f 3. Identify the armature and fields, 4. Measuring motor Notes This series of fove Color.Sound f resistance: voltmeter-ammeter method, 5. Counter electrmotive Notes This series of fove Color.Sound f force.
