Energy efficient motor drives
D G Holmes
6 points * 36 hours of lectures, tutorials and laboratory work * Second semester * Clayton
Objectives The student is expected to acquire an understanding of the structures and principles of operation of variable speed drive systems for ac and dc motors, the principles of power electronic conversion used in variable speed drive systems, the role of control theory in the operation of a drive system, design and performance issues for dc and ac motors, and where the various losses occur in a variable speed drive system. The student is also expected to be able to determine appropriate performance criteria for different types of variable speed drive systems, and to be able to choose between various alternatives to suit particular applications.
Synopsis Principles of variable speed drive systems, power electronic switching devices, converter topologies and modulation, open and closed loop control systems, dc and ac electrical motors, dc and ac motor drive systems, losses in electric motors, high performance drive systems, improved efficiency drive systems.
Assessment Examination (2 hours): 70% * Written: 15% * Laboratory work: 15%
