DESCRIPTION - summary of the module content

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. 

AIMS - intentions of the module

The aim of this module to help build a fundamental knowledge and understanding of the different types of electric machines used in industry and everyday life, their operation, characteristics, performance and applications. This module also aims to introduce the fundamental concepts of semiconductor power electronics 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.
