Description

This subject aims to introduce to students modern electrical machines and drives, including introduction of electrical machine technology and applications, Matlab/Simulink models of power electronic converters, single phase and three phase transformers, high frequency transformers used in power electronic circuits, fundamentals of electrical drives, DC machines and drives, synchronous machines and drives, induction machines and drives, and switched reluctance machines. Issues such as variable speed drive and energy efficiency are addressed. The numerical simulation of various modern drive systems is presented. The subject is delivered through lectures, tutorials, laboratory experiments and assignments. Students are also required to conduct four labs for measuring the parameters and performance of various electrical machines and four assignments for numerical simulation of various electrical machines and drive systems with the help of the lecturer and tutor.

Subject learning objectives (SLOs)

Upon successful completion of this subject students should be able to:

1. Identify, interpret, and analyze the stakeholder needs of electrical machines and drive systems based on a sound understanding of the important socio-economical role that the high performance intelligent electrical drive technology plays in the modern world, and the critical issue of energy efficiency and its environmental significance in terms of the reduction of greenhouse gas emission. (B.1)
2. Practice sound judgment, resource management, and work within challenging constraints and specifications through the laboratory work and assignment. (D.1)
3. Apply excellent technical expertise to identify, analyze, and solve technical problems in electrical machines and drive systems, and to apply the knowledge to practical industry systems and appliances. (D.1)
4. Follow new technological development in the field of electrical machines and drive systems, and apply new technologies in their future work. (D.1)
5. Be skillful in technical writing and presentation of electrical machine technology and teamwork skills through the laboratory work and assignment. (E.1)
6. Be aware of global perspectives (needs, rules/regulations, and specifications). (B.1)

Course intended learning outcomes (CILOs)

This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):

  • Socially Responsible: FEIT graduates identify, engage, interpret and analyse stakeholder needs and cultural perspectives, establish priorities and goals, and identify constraints, uncertainties and risks (social, ethical, cultural, legislative, environmental, economics etc.) to define the system requirements. (B.1)
  • Technically Proficient: FEIT graduates apply abstraction, mathematics and discipline fundamentals, software, tools and techniques to evaluate, implement and operate systems. (D.1)
  • Collaborative and Communicative: FEIT graduates work as an effective member or leader of diverse teams, communicating effectively and operating within cross-disciplinary and cross-cultural contexts in the workplace. (E.1)

Contribution to the development of graduate attributes

Engineers Australia Stage 1 Competencies

This subject contributes to the development of the following Engineers Australia Stage 1 Competencies:

  • 1.3. In-depth understanding of specialist bodies of knowledge within the engineering discipline.
  • 1.6. Understanding of the scope, principles, norms, accountabilities and bounds of sustainable engineering practice in the specific discipline.
  • 2.2. Fluent application of engineering techniques, tools and resources.
  • 3.2. Effective oral and written communication in professional and lay domains.

Teaching and learning strategies

This subject uses a problem based learning strategy that allows students to research and develop their own solutions to complex electrical machines and drive systems. A series of practice based laboratory and assignment tasks are designed to reflect current industry practice. Class time occurs in a two hour lecture and a three hour laboratory/tutorial session per week.

Student learning is supported in the following way:

(1) Prior to each lecture session, students are required to read the corresponding chapters of lecture notes available in Canvas and the textbook and reference book listed in the subject outline.

(2) Prior to each lab, students will be required to study the Lab Notes and associated readings and prepare questions, experimental procedures, and data processing and analysis methods. In the lab, students will work in groups of 4 on their laboratory tasks. During the lab, the lab tutor will be available for discussion about the experimental procedure and expected testing results. At the end of the lab, the lab tutor will be available to review the lab work and provide immediate feedback. Although the experiments are done in groups, each student is required to write his/her individual lab reports, and submit it in pdf format by email to the lab tutor by the due dates listed in the subject timetable. The marked lab reports will be returned to students with feedback and comments.

(3) Each of the assignments should be done individually. Each student should submit his/her reports in pdf format by email to the tutorial tutor by the due dates listed in the subject timetable. The tutorial tutor will be available for one-on-one consultations on particular aspects of assignment work during the tutorial sessions, and after marking, the tutor will return the assignment reports to the students with feedback and comments.
