ELECTRICAL MACHINES FOR TEACHING PURPOSES

The purpose of an electrical machines laboratory is (a) to provide the student with practical knowledge of the handling of electrical machines, (b) to correlate the theoretical classroom treatment with actual machine characteristics, (c) to demonstrate the most suitable testing techniques, and (d) to provide facilities for advanced work on machine operation and performance in integrated systems. Space and cost are usually of overriding importance, so great care is needed in the choice of suitable units and their layout in the laboratory, in order to achieve maximum efficiency of utilisation. Where possible, a machines laboratory should be used only for machines experiments, so that the most efficient layout for this purpose can be adopted without compromise.
