This unit will study the design and operation of high-performance AC permanent magnet and induction motor electrical drives used in the electric propulsion of land and air vehicles, encompassing the power electronics, control and electrical machine components. During the unit, students will build a software tool for specifying and sizing an electrical machine drive and this will be used to explore case study electric vehicle, electric vertical take-off and landing air vehicle and other propulsion drive applications used in low carbon transport.
The equivalent circuits and defining equations that model the operation of AC permanent magnet and induction machines will be reviewed and mathematical descriptions of flux vector control methods for AC machines developed. Typical control and sensor feedback structures used in power electronic controlled AC drives will be derived. In tandem the fundamental electromagnetic behaviour of electrical machines will be reviewed and contextualised in terms of flux vector operation. Techniques used to size the magnetic circuit and the design of the windings of an AC electrical machine will be developed. The relationship between the electrical machine design and the inverter VA rating will be established to give an understanding of system level impact of design decision. Matlab/SIMULINK based drive system simulations and electrical machine design software will be used to inform this understanding.
Upon successful completion of the unit students will be able to:
Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.
Design case study assignment (100%) (All ILOs)
The study will test the students understanding in applying the analytical techniques, design tools and simulation models developed in the unit to an exemplar propulsion drive.
If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.
If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENGM0034).
How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours
of study to complete. Your total learning time is made up of contact time, directed learning tasks,
independent learning and assessment activity.
See the Faculty workload statement relating to this unit for more information.
Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit.
The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an
assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates
within the Regulations and Code of Practice for Taught Programmes.
