Aims

To provide a thorough basis for electrical machines study at advanced level.

To be able to analyse electrical machines in numerical and 2D finite element simulation systems.

To have an overview of Electrical Machines in the modern world and in the context of the Electrification Revolution.

Outline Of Syllabus

Mechanical Modelling and transient behaviour

Transients in dc machine, time constants, distinction between electromechanical and electrical transients, linearization concepts, numerical methods. Electromechanical transients in ac machines, natural oscillation frequencies, discussion of behaviour in physical terms, with reference to equivalent circuits.



DC Machines as the basis for the general machine model

Torque speed characteristics

Armature reaction, compensating windings, commutation, interpoles.

Brushless dc drives: Principles of operation: sinusoidal and trapezoidal drives. Relationship to brushless dc machine.



AC Synchronous Machines

Salient pole Synchronous Machine -dq approach: -

DQ axis reactance models, salient pole phasor diagrams, torque and power calculations, reluctance and excitation torque, voltage and current fed performance, wound rotor and PM types.

Circuit analysis of electrical machines: -

Permanent magnet synchronous machines: salient pole operation and the application of field weakening.



AC asynchronous machines

Induction machine models for control purpose; relationship of induction motor models to synchronous and dc.



General Machine Theory

An understanding of alternative reference frames, dq, alpha/beta, space vector, forward/backward, rotor/stator/air gap and their transformations for each machine type. An explanation of the merit of each derived machine model.

Development of circuit models from dc machine and synchronous machine routs. Impedance matrix; instantaneous and phasor variables; real-coil and pseudo-stationary coil machines; expressions for torque and power, transformation of variables with power invariance, examples; general two-axis machine.



Electrical machines driving the Electrification Revolution

Intersp[ersed throughout the course, research into automotive and aerospace applications of electrical machines and modern manufacturing methods and materials in electrical machines. To include industrial guest lecturers.

Teaching Rationale And Relationship

Non-synchronous videos provide the core material (explainers) whilst PiP lectures will be used to cover worked examples, practice simulations and to take general questions. These will take place in a mix of computing labs and lecture or seminar rooms. Additional individual support will be offered in a surgery slot timed toward the end of each unit. Software training and problem solving is introduced and practiced through PiP lectures in computing labs.

The PiP lectures can be replaced with online synchronous sessions support by non-synchronous videos if the public health situation requires it.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

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.
