WM994-15 Electrical Drivetrains
Introductory description
39 contact hours over 1 week consisting of interactive presentations, question and answer sessions and discussion, videos, small group exercises and problem classes.
The module includes a significant practical element (~30%) where students gain hands-on experience of electric machine characterisation and testing as well as classroom-based investigation and consolidation of the control technology employed.
Module aims
The purpose of the module is for the students to learn about advanced propulsion technologies for hybrid and electric vehicles. In particular, the learning is focused on electric machines appropriate for hybrid and electric vehicles. The learning will also be based on how to design, drive and control these electric machines particularly in the context of hybrid and electric vehicles.
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.
- Electric machine types and characteristics.
- Design of control for electric machines.
- Use of power electronics in electric machines.
- The future of propulsion technology in the automotive industry.
- Hands-on practical: Electric machine characterisation.
- Hands-on practical: Electric machine drivetrain and efficiency evaluation.
- Hands-on practical: Electric machine control and test design class.
Learning outcomes
By the end of the module, students should be able to:
- 1. Interpret electric machine technologies, operation and their characteristics.
- 2. Demonstrate comprehensive understanding of control methods for different machine technologies.
- 3. Demonstrate comprehensive understanding of power electronics devices and circuits.
- 4. Understand practicalities of electrical drivetrains in real-world application to hybrid and electric vehicles
- 5. Systematically compare electric drivetrain designs for hybrid and electric vehicles.

Assessment group D
| Weighting | Study time | |
|---|---|---|
| Evaluation of practical activities and technology application | 80% | 80 hours |
|
PMA is comprised of two parts. The first part will cover ILOs 1, 4 and 5 or ILOs 2 to 5, and it is related to the work completed in the practical sessions. The student needs to choose one practical to report out of the total of three practicals completed. The number of ILOs covered depends on the practical the student decides to choose. The second part covers all ILOs. Part 2 is related to discuss a typical electric machine configuration and their associated control and power electronics system. |
||
| Electric Machine control design and test | 20% | 6 hours |
|
Design and test activity in MATLAB/Simulink to control electric machines. ILO 2 is assessed. |
