EEE3002 : Electrical Machines

Semester 1 Credit Value: 10
ECTS Credits: 5.0


Completion of the steady state analysis of electrical machines and an extension to their dynamic performance.

Outline Of Syllabus

General theory of electrical machines (Parks equation) and its application to DC and synchronous machines, links to the steady state per phase model.

Mechanical modelling by the use of free body diagrams to derive system response of scenarios involving electrical machines, flywheels, external loads, gears, friction and rigid / non- rigid shafts.

Transient and steady state solution, including using of time constant, distinction between electromechanical and electrical transients, linearization concepts, numerical methods.

Analysis of DC machines by the use and derivation of equivalent circuits. Basic understanding of alternative wiring configurations, flux travel and architecture in DC machines, including the universal machine.

Analysis of Synchronous machines by the equivalent circuit and phasor diagrams. 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.

Analysis of three phase induction machines including the derivation of a useable equivalent circuit, expressions for torque, speed and power flow. Layout of windings and basic architecture.

Understanding of operation of Single Phase Induction Motor, derivation of equivalent circuit showing forward and backward wave effects; torque characteristics, f and b components; practical methods of improving starting characteristics.

Understanding of Reluctance and Synchronous reactance machines, principles of operation and models for operating characteristics.

Teaching Rationale And Relationship

Lectures provide the core material and guidance for further reading, problem solving and practice are integrated into the lecture structure.
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.
The online unit assessments will help the students to reflect on what has been learnt so far and give feedback throughout the course.
The mid-term assignment will help to bring together course material and simulation skills in a problem based setting and will provide feedback well ahead of the final exam.

Assessment Methods

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

Assessment Rationale And Relationship

Each online assessment will allow the students to demonstrate their knowledge on a single teaching unit; Background and mechanical modelling, Induction machines, DC machines, Synchronous machines. The tests will give instant feedback which can be reflected upon as the course progresses.
The midterm assignment will allow the students to demonstrate a deeper understanding in a problem based setting. Again feedback will be given prior to the end of the autumn term to allow the students to reflect.
The examination allows students to demonstrate their problem solving skills together with their knowledge and understanding of the subject matter outlined in the lectures.

Semester 1 Study Abroad students will be able to sit the final assessment earlier.
