EE40FE: ELECTRICAL MACHINES AND DRIVES (2020-2021)

Last modified: 05 Aug 2021 13:04

Course Overview

This course examines the performance and control of electrical machines and drives. Transient performance of various electrical machines (induction, synchronous and DC) is discussed using two-axis-machine theory. Steady state performance is also considered. Simulation techniques are used as appropriate in studying both transient and steady state performance of the electrical machines and drives. Medium and high-performance AC drives are considered, including V/f and vector control drives. Modern AC machine control in rotating DQ co-ordinate frame is studied in some detail. DC machine drives (thyristor-controlled and transistor-controlled drives) are discussed and analysed.
