Location
Prerequisites
NEF2251 - Fundamentals of Electrical and Electronic Engineering
(Or equivalent to be determined by unit coordinator)
Co-requisites
(Corequisite units must be studied concurrently with this unit)
Overview
This unit introduces the principles and applications of magnetic circuits and electrical machines. Students will analyse magnetic systems and calculate forces on moving charges, followed by the study of DC machines, transformers, induction motors, and synchronous machines. Emphasis is placed on equivalent circuit models, performance analysis, and practical operation. Topics include transformer efficiency, induction motor starting methods, and synchronous generator performance, including power factor correction and reactive power control. Laboratory activities reinforce theoretical concepts through testing and performance evaluation of real machines.
Learning Outcomes
On successful completion of this unit, students will be able to:
- Apply the fundamental principles of electromagnetic and mechanical energy conversion to analyse electrical machines;
- Describe the structure and function of key components in DC, induction, and synchronous machines;
- Develop and apply equivalent circuit models to evaluate performance under various operating conditions;
- Analyse and interpret the operation of transformers and power systems using theoretical and experimental data; and
- Evaluate motor starting methods and assess the industrial applications of AC machines for efficiency, sustainability and suitability.
Assessment
For Melbourne campuses
Assessment type: Report | Grade: 40%
Laboratory Practicals (3000 words (Group of two))
Assessment type: Test | Grade: 60%
Two In-class problem solving exercises (30% each, 60 minutes each) (Individual)
Tests: These secure invigilated in class assessments have an unpredictable problem-solving scenario format that tests understanding, requires explanation of reasoning and process, and involves applying knowledge to new contexts.
Report: This secure assessment ensures accountability by requiring students to perform hands on lab tasks under supervision. Real-time observation and process-focused questioning verify understanding and application of analytical skills. Structured group lab report documenting design, implementation, and validation processes in detail. Progressive milestone checks, documented collaboration and individual contributions ensure accountability and support verification of each student’s engagement. Explicit evaluation of individual contributions further supports the secure assessment and assurance of each student’s achievement of learning outcomes.
