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.
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.

Assessment group A3
| Weighting | Study time | Eligible for self-certification | |
|---|---|---|---|
Assessment component |
|||
| Design of a Permanent Magnet Synchronous Machine | 80% | 42 hours | Yes (extension) |
|
Individually, students design a Permanent Magnet Synchronous Machine (PMSM), applying relevant principles and methodologies to develop their designs, including thermal and mechanical aspects. They should use scientific resources to support their design process and consider the manufacturing and cost aspects of their design. They then submit a report explaining their process and outcomes. |

| Electromagnetic design of induction machine | 20% | 18 hours | No |
|
Within their groups, students complete activities and review resources on the electromagnetic design of an induction machine for a Tesla electric vehicle. Each group then writes and submits a report detailing their completed tasks and demonstrating their understanding of the subject matter. Peer adjustment will be used to reflect individual contributions within the group. |
