Electrical Machines and Transformers ENG231


This unit introduces students to the operation principles and characteristics of electrical machines and transformers as well as the physics behind the operation of these machines. Students will gain a thorough understanding of transformers, DC motors, induction machines and synchronous machines. This unit prepares students to undertake future studies in Electrical Power Engineering.

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

Learning Outcomes

  • Explain the operation of motors, generators and transformers using knowledge of magnetic circuit laws and fundamental circuit laws.
  • Solve problems related to the operation, characteristics and implementation of motors, generators and transformers.
  • Determine electric and magnetic field strengths and their effects in and around electrical machinery.
  • Predict and model the effects of magnetic induction on moving parts of machinery by making use of Maxwell's equations.
  • Analyse, draw conclusions and report the results of physics and electrical machines experiments.
