Rotating machinery explained - DC motors : principles of operation - Part one Bergwall Productions [VHS Tapes].

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 filed 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 regulate them. Starting with a simple DC Motor, the Notes This series of five Color/Sound f principles of operations are described and expanded to Notes This series of five Color/Sound f explain the connections are uses of shunt, series, and Notes This series of five Color/Sound f compound motors. The method used to identify the field are Notes This series of five Color/Sound f armature terminals of a motor is demonstrated and the counter Notes This series of five Color/Sound f EMF is measured.
