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:

  1. Analyse and design electrical power circuits.
  2. Apply the knowledge of the working principles of transformers in the context of power system applications.
  3. Assess the applications of single-phase and stepper motors.
  4. Demonstrate knowledge of mechanics and heat transfer principles in relation to electo-mechanical systems.
  5. Demonstrate knowledge of the practical uses of electrical machines in power generation and conversion.
  6. Research new developments in the field ofelectromechanical systems and reflect critically on their significance to engineering practice.

Unit Content

  1. Active, reactive and apparent power and three-phase circuits.
  2. Direct-current generators.
  3. Direct-current motors.
  4. Efficiency and heating of electrical machines.
  5. Fundamentals of electricity, magnetism, mechanics and heat with relation to electro-mechanical systems.
  6. Ideal, practical and special transformers, three-phase transformers.
  7. Single-phase motors.
  8. Stepper motors.
  9. Synchronous generators, their construction and properties.
  10. Synchronous motors and their applications.
  11. Three-phase induction machines and their applications.

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.
