Module description
Electric machines play an important role in industry, manufacturing, transportation and every aspect of our life. This module provides fundamental understanding of the main types of electric machines used in industry including DC machines, induction and synchronous machines. You will learn their principles of operation, equivalent circuits, control schemes and applications. This module will also cover semiconductor power electronics as important control devices and circuits in modern electric machine systems. The theory will be supported by a series of hands-on practical experiments to understand the operation and design of electric machines and power electronic circuits for real-world applications.
Module aims - intentions of the module
The aim of this module is to build a fundamental knowledge and understanding of the different types of electric machines used in industry and their applications , and develop the ability to analyse their operation, characteristics, and performance. This module also aims to develop fundamental knowledge of semiconductor power electronics and the ability to analyse and design power converter circuits as control elements of electric machine systems. Through lectures, tutorials, worksheets and hands-on practical sessions, you will acquire knowledge and skill for the analyses of electric machines and power electronics for real-world applications.
