Aims
To build on a basic understanding of electrical machines to bring the student to an advanced level where they will understand the various machine topologies, be able to develop analytical models to obtain operating characteristics, be able to simulate, analyse, and extract results and performance data for a variety of machines using numerical and finite element simulation methods.
To experience a laboratory setting and extract, process and interpret experimental results.
The student will also gain a contemporary understanding of research in electrical machines and their applications, in particular emerging trends in automotive, aerospace, new manufacturing technologies and how sustainability and the circular economy affect electrical machines and their applications.
Outline Of Syllabus
Mechanical Modelling
Understanding the machine and load as a mechanical system and being able to analyse steady state and transient effects. Understand the source of losses and how these can be reduced for improved efficiency.
DC Machines
Understanding their principle of operation as a basis for more complex machines, derive and understand equivalent circuit and torque-speed characteristics for various DC, Universal and Brushless DC machines. Understand the drive and control arrangements for BLDC.
Synchronous machines
Understanding the principle of a rotating magnetic field, synchronised with the rotor field. Derive and understand power and peak torque and speed operating points and how field weakening is used to extend speed range.
Asynchronous machines
Understanding principles of operation, obtaining parameters by test, torque speed characteristics and the Doubly Fed Induction Generator
Electrical Machine Applications
In groups investigate contemporary machines research in Automotive and Aerospace applications, New manufacturing technologies, Sustainability and the circular economy as pertains electrical machines.

Teaching Rationale And Relationship
Pre-recorded videos provide the core material for individual study.
In the lecture theatre and computer rooms this knowledge will be applied to worked examples covering analysis and simulation of electrical machines.
A variety of analytical examples will be worked as a class. Computer based simulation problems will allow the students to gain a deeper understanding of the characteristics and principles of the electrical machines being studied, and an ability to link the mathematical models developed to the electrical machine operation.
Group work will give us the opportunity to examine contemporary research material from a variety of journals extract top level information and make a short presentation. over the course of these sessions students will be exposed to machine applications in aerospace automotive new manufacturing and the circular economy.
Laboratory work will expose the student to a working machine where they will extract operating results, interpret and present these in graphs.
Assessment Methods
The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship
The formative assessments will allow the students to practice working as a group, gathering relevant information in a limited time, presenting to an audience. The laboratory session will give the student experimental experience and practise data gathering and clear presentation skills.
The summative assessments will allow the students to demonstrate a deeper understanding in a problem-based setting where they will demonstrate their knowledge using analytical skills, simulation methods, the interpretation of results, and the application of electrical machines in society.
