  • Level 3 core unit in the Automation and Robotics Engineering; Electrical and Electronic Engineering major sequences
Outcomes

Students are able to (1) demonstrate an ability to work effectively in laboratory teams; (2) analyse two basic principles (generation of EMF and torque) that govern electromagnetic energy conversion and differentiate between motor and generator operation; (3) analyse the performance (regulation, losses and efficiency) of DC machines, transformers, induction and synchronous machines based on the equivalent circuits; (4) explain the working principle of transformers and AC electrical machines by using phasor diagrams ; (5) analyse torque-speed characteristics to develop speed control techniques for DC and induction motors; (6) develop transmission line parameters and power system representation; and (7) demonstrate compliance with work, health and safety regulations, codes and standards when operating electrical machines.

Assessment

Indicative assessments in this unit are as follows: (1) laboratory assignments and reports; (2) class tests; and (3) a final examination. Further information is available in the unit outline.



Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

  • 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.
  • Visit the Essential Textbooks website to see if any textbooks are required for this Unit. The website is updated regularly so content may change. Students are recommended to purchase Essential Textbooks, but a limited number of copies of all Essential Textbooks are held in the Library in print, and as an ebook where possible. Recommended readings for the unit can be accessed in Unit Readings directly through the Learning Management System (LMS).
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
