OBJECTIVESDC GeneratorsTERMINAL OBJECTIVE1.0 Given the type and application of a direct current (DC) generator, DESCRIBE theoperating characteristics of that generator including methods of voltage production,advantages of each type, and voltage-vs-load characteristics.ENABLING OBJECTIVES1.1DEFINE terminal voltage as it applies to DC generators.1.2DEFINE counter-electromotive force (CEMF) as it applies to a DC machine.1.3DESCRIBE the effects of commutation in a DC generator.1.4STATE the purpose of each of the following components of a DC machine:a. Armatureb. Rotorc. Statord. Field1.5LIST the three conditions necessary to induce a voltage into a conductor.1.6 Using the left-hand rule of generators, DETERMINE the direction of the magnetic field,the motion of the conductor, or the direction of current induced into a conductor.1.7DESCRIBE how terminal voltage of a DC generator is adjusted.1.8STATE the basis behind each of the four DC generator ratings.1.9LIST the four internal losses found in a DC generator.1.10DESCRIBE the differences in construction between a shunt-wound and a series-woundDC generator with respect to the relationship between the field and the armature.1.11DESCRIBE the relationship between the shunt and series fields for cumulatively-compounded and differentially-compounded DC generators.ES-05 Page vi Rev. 0
