This unit introduces various forms of linear and rotary electromechanical energy conversion systems. The basic concepts of electromagnetic theory are revised and applied in the study of voice coil and self-excited linear and rotary actuators. An equivalent circuit model for the complete electromechanical system is developed which provides a basis for subsequent study of dynamic behaviour. The DC machine output characteristics are revised and its operation within a variable speed drive is presented. The operation of power electronic servo amplifiers and phase-controlled rectifiers are also introduced. As an introduction to the AC machine, the concept of the rotating magnetic field is discussed. Subsequent study concentrates on the asynchronous motor where its operation is described, the equivalent circuit is derived and its output characteristics under fixed and variable frequency excitation are analysed.
Having completed this unit, a successful student will be able to:
Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.
If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENG20002).
How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours
of study to complete. Your total learning time is made up of contact time, directed learning tasks,
independent learning and assessment activity.
See the Faculty workload statement relating to this unit for more information.
Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit.
The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an
assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates
within the Regulations and Code of Practice for Taught Programmes.
