Aims

To give a good grounding and experience in the physical design of electrical machines and a broad understanding electrical drives selection criteria.

To gain the skills to produce outline designs of electrical machine drive systems to a given specification.

To be skilled in machine drive design for modern and emerging applications, including electric vehicle drives.

Outline Of Syllabus

The design of modern electrical drives, with consideration of the machine, power electronics and control requirements. Comparisons are made between drive types and typical application considered.



An overview of electrical machine drives and how they can contribute to net zero carbon targets:

Impact of raw materials

New and emerging applications

Design trends and future challenges


Machines:

Magnetic circuits and materials, modelling; magnetic and electric loadings;

thermal design; steady state and transient design and analysis;

winding design, pitching and distributing windings, single tooth windings,

choice of pole number, phase number, voltages and turns

Choice of rotor and stator dimensions, leading to outline design concepts

Permanent magnet machines; induction machines; switched reluctance machines; wound rotor synchronous machines

Drives:

Field oriented control of ac machines;

Field weakening

Applications and characteristics of different ac drives;

Comparative evaluation of different drives.

Use of commercially available software to perform machine analysis and design.

Teaching Rationale And Relationship

Lectures provide the core material as well as guidance for further reading. Tutorial questions offer the opportunity for practice in analysis and synthesis and where necessary more direct tuition can be offered to smaller student groups. Some aspects of the course are further re-enforced through laboratory demonstrations.

The computer aided design exercises test the students' core knowledge and understanding of machine design principles including making suitable assumptions, simplifications and mathematical analysis. The coursework involves the use of commercially available machine design software, which is introduced in a lecture and supplemented by worked tutorials. The coursework allows the students to demonstrate their ability to use the software, show some engineering creativity and further develop their communication skills. Laboratories are formative in nature, giving practical experience and understanding.

Assessment Rationale And Relationship

Design is a creative concept and so it is most appropriate to allow the students’ time to do this via projects which are then assessed by reports. Two projects are given: one focused upon the machine design and one upon electric drive design. The projects will allow the students to use state of the art design software to create designs against a specification of a named application. Their ability to understand, analyse and synthesis systems will be tested, covering almost all aspects of the knowledge and skills outcomes of the module.
