Rotating machinery explained - DC motors : measuring motor resistence - voltmeter-ammeter method Bergwall Productions. [VHS Tapes].

Notes This series of five Color/Sound films on Direct Current Notes This series of five Color/Sound f Motorsis the foundation for the understanding of the field of Notes This series of five Color/Sound f electrical rotating machinery and the controls used to Notes This series of five Color/Sound f regulate 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 used to identify the field and armature Notes This series of five Color/Sound f terminals of a motor is demonstrated and the Counter 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, Notes This series of five Color/Sound f 3. Identify the armature and fields, 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.
