Electrical Machine Design and Manufacturing WM983-15

Assessment type

Written report

Weighting of mark

The marking is done considering 100 marks are available.

The submitted document will be marked holistically considering the module learning outcomes (LO2-6), and according to the following criteria:

· Comprehension and analysis: 70 marks

· Presentation: 30 marks

See marking grid for more details.

If this is a re-submission assessment, the combined mark will be capped at 50%, when all the LOs are at least partially met.

The PMA is worth 80% of the module final mark.

Assessment brief

PMA First Submission:

Permanent Magnet Synchronous Machines (PMSM) offer many degrees of freedom. Your task is to design the optimal PMSM to meet the specifications for Vehicle 1. In your design, you should address the following issues:

1. Initial Motor Selection and Optimization: Choose an initial motor based on available templates, then attempt to optimize it. Justify your choice of the initial motor and explain any changes made during design iterations, possibly including sensitivity analyses. One final design should be qualified in terms of electromagnetic, thermal, and mechanical performance.

2. Manufacturing Protocol: Design a manufacturing protocol for the motor you’ve designed. Discuss manufacturing challenges and quantify the impact of possible manufacturing issues on performance.

3. Cost Analysis: Perform. a cost analysis that considers both materials and the manufacturing process.

4. Reference Utilization: Leverage additional references, such as technical papers, to improve your work.

Word count

Word count only considers the number of words of the main body text. Tables, figures, headings, references, list of contents, list of abbreviations, list of figures, list of tables and appendix are not contributing to the word count. The submitted file should not exceed 30 pages.

Inappropriate deviation of word counts, and penalisation is defined as follows:

· The number of words of the PMA (3000 words) is within (+/-) 10% of the recommended word counts – no penalisation.

· The number of words is between (+/-) 10% to 20% of the recommended word counts – 5 marks in Effort and Presentation shall be reduced.

· The number of words is between (+/-) 20% to 30% of the recommended word counts – 10 marks in Effort and Presentation shall be reduced.

· The number of words is over 30% of the recommended word counts – 15 marks in Effort and Presentation shall be reduced.

Inappropriate usage of appendix or figures/tables (i.e., irrelevant, not referred to or not supporting the main text, or text repeatedly inserted into table, etc…) will be penalized in a similar manner as word count deviation.

Module learning outcomes (numbered)

LO1- Work in a team to differentiate electric machine technologies, considering their operation, characteristics, mechanical aspects, and cooling concepts [AHEP4;7, M2, M4]

LO2- Evaluate and simulate the electromagnetic, mechanical, and thermal performance of electric machines by working on a group or individual project [AHEP4;7, M3, M4]

LO3- Interpret the practicality of electric machine designs considering manufacturing processes and cost [AHEP4;7, M5, M7]

LO4- Systematically design electric machines for hybrid/electric vehicles , with considerations of powertrain architecture, integration and influence of manufacturing [AHEP4;7, M1, M2]

LO5- Critique design trade-offs and technological advances of electric machines for electric and hybrid vehicles [AHEP4;7, M4, M7]

LO6- Select and critically evaluate technical literature and other sources of information to solve complex problems [AHEP4;7, M2, M4]

Marking guidelines

See marking grid.

Marking guidelines are in line with departmental policy and guidance for the level.

There are degrees of freedom on how to demonstrate the LOs and in which parts of your PMA. It is recommended to create a map of your contents and verify that each LO is addressed within the word count. Quality and depth should be prioritised over multiple repeats of the same investigations.

In addition, please consider the following points:

· Your assignment must be written in a technical/academic style.

· The format of the presentation should be a single, concise document.

· Relevant diagrams and calculations should be included.

· Sanitisation of the results, particularly from lengthy or complex calculations, is strongly encouraged.

Specific references to the course notes or references can be included but LO6 can only be met with new references a variety of high-quality references to demonstrate learning beyond the taught material.

Writing your Post-Module Assignment (PMA): specific other advice for WMG's Postgraduate Taught Students

As a postgraduate level student in WMG you may have some concerns about your ability to write at the high standard needed. This short guide is intended to supply general guidance and advice. It is important that if you have any questions, you discuss them with your module tutor. Remember, in writing your PMA you need to meet the expectations of the reader and University.

A good PMA generally requires you to answer the question and to include…

1. A title, with your student number, module, lecturer's name and any other documentation required by the University.

2. A contents page and if proper, an abstract.

3. An introduction which acts as a 'map' to the rest of the document, describing the aim or purpose of the work and explaining how this aim is achieved. At this point it is usually helpful to paraphrase your conclusion.

4. Evidence of a suitable level of background reading of relevant texts.

5. Evidence of systematic and clear thinking, indicative of good planning and organisation.

6. Writing which makes sense, is clearly and carefully presented (proof-read and grammar checked).

7. A critical style. of writing which compares the main theories, concepts and arguments with conclusions that are based in evidence presented.

8. Important levels of exact academic referencing.

9. A logical and well-defined structure with headings and subheadings.

10. Clearly labelled and well-presented diagrams and other graphics that are discussed in the text.

11. Adherence to usual academic standards including length and a prompt submission.

12. A reference section in which every source that is cited in the text is listed.
