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.

33 hours

This is the total time spent in lectures, tutorials and other class teaching.

Teaching Breakdown


1st Attempt: 1 three-hour written examination (80%); course assessment (20%).

Formative Assessment

The course will include opportunities to assess individual progress with the concepts and material being delivered via continuous assessment exercises. Feedback will be given over the course during the tutorial sessions.


Marked submissions (typically via MyAberdeen) will be returned to the students promptly, including feedback on the laboratory exercises. Whole-class feedback and solutions to past assignment or exams are provided via MyAberdeen.
