WM983-15 Electrical machine design and manufacturing
Introductory description
This module provides in-depth knowledge of electric machine technologies, design and manufacturing for hybrid and electric vehicles. The modelling and design of electric machines are covered in depth through lectures and activities. Mechanical and thermal design fundamentals are covered. This module also include aspects of control, novel topologies, noise and vibration of electric machines in the context of electric vehicles, for today and future technologies. When this module is delivered on DA Programmes, it is delivered in a 1-week block with 6 weeks to submit, rather than over 4 week.
Module aims
The students will gain a high-standard of technical knowledge about electric machines, allowing them to act as component experts, understand stakeholder/interface requirements and limitations and liaise with researchers to translate state-of-art into business opportunities.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Assessment group A4
| Weighting | Study time | Eligible for self-certification | |
|---|---|---|---|
Assessment component |
|||
| Thermal and Mechanical Design of a PMSM | 80% | 48 hours | Yes (extension) |
|
Individually, students design the thermal and mechanical aspects of a Permanent Magnet Synchronous Machine (PMSM) to meet the specifications for Vehicle 1, applying relevant principles and methodologies in their development. They should use scientific resources to support their design process and consider the manufacturing and cost implications of their design choices. They then submit a report explaining their process and outcomes. |
