DESCRIPTION
|
|
This unit builds upon fundamental electric circuit and physics principles to introduce the concepts of modern electro-mechanical systems, including dc, ac single phase and polyphase electrical machines. Various types of transformers are also covered. Students will gain theoretical and practical experience with a number of electro-mechanical power conversion and power generation systems through lecture and laboratory activities.
|
| |
| LEARNING OUTCOMES |
|
On completion of this unit, students should be able to:
- analyse and design electrical power circuits;
- demonstrate knowledge of mechanics and heat transfer principles in relation to electo-mechanical systems;
- apply the knowledge of the working principles of transformers in the context of power system applications;
- demonstrate knowledge of the practical uses of electrical machines in power generation and conversion.
|
| |

To be eligible to pass this unit, students must pass the end-of-semester examination.
*Due to professional competency skill development associated with this unit, participation in all laboratory sessions and successful completion of associated tasks is a mandatory requirement for passing this unit. Students who are unable to attend a lab session for a legitimate reason will need to arrange a make-up session with their lecturer. Students who fail to complete all required laboratory tasks without legitimate cause may be awarded an FI grade (Fail Incomplete). |

Academic Misconduct
Edith Cowan University has firm rules governing academic misconduct and there are substantial penalties that can be applied to students who are found in breach of these rules. Academic misconduct includes, but is not limited to:
- plagiarism;
- unauthorised collaboration;
- cheating in examinations;
- theft of other students’ work.
Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere.
The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.
