Details of Learning Activities
|
You will involve in the following learning activities to meet requirements for competency and stage 1 competencies for Engineering Associates Learning and simulated work activities to demonstrate an understanding of typical motor problems encountered in meeting performance requirements and compliance standards, revising a motor operating parameters and dealing with motor malfunctions.
* Classroom tutorial activities to consolidate the theory of three-phase electrical systems, operating principles of single-phase motor, three-phase motor, universal motor, controlling devices for various motors, various motor protection devices.
*Practical exercises involving design and construction of simple electrical motor control circuits and participate in research activities in the application of different control devices for various electrical motors. It involves the development of testing procedure to verify the performance specification, diagnosis of faults in the systems and completion of the commission.
* Research activities to investigate control devices for various types of electrical motors, and various motor protection device applications. It is expected that students would require approximately 20% of course hours to be allocated for independent study to do motor selection criteria, equivalent electrical circuit, motor control circuit design, construction, testing and problem solving activities
