Details for undergraduate courses
  • Level 3 core unit in the Electrical specialisation in the Engineering Science major sequence
  • Category B broadening unit for students
  • Level 3 elective
Content
This unit covers the theory of three-phase circuits, transformer models, DC and AC machines (synchronous and induction), equivalent circuits and performance relations (torque-speed relation, speed and voltage regulation, efficiency calculation).
Outcomes
Students are able to (1) demonstrate an ability to work effectively in laboratory teams; (2) analyse and compare two basic principles (generation of EMF and torque) that govern the electromagnetic energy conversion; (3) develop equivalent circuits for DC machines, transformers, induction and synchronous machines; (4) develop phasor diagrams for transformers, induction and synchronous machines; (5) using equivalent circuits, analyse and assess the performance (regulation, losses and efficiency) of DC machines, transformers, induction and synchronous machines; (6) differentiate between motor and generator operations for DC, induction and synchronous machines; (7) analyse torque-speed characteristics to develop speed control techniques for DC and induction motors; (8) develop transmission line parameters and power system representation; and (9) explain the working of special purpose electrical machines including single phase induction motors.
Assessment
Typically this unit is assessed in the following ways: (1) laboratory assignments and reports; (2) class tests; and (3) a final examination. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
