Module summary

The teaching and assessment methods shown below will be kept under review during 2021-22. In particular, if conditions allow for alternative formats of delivery, we may amend the timetable and schedule appropriate classes in addition to (or in place of) any online activities/sessions. Where learning activities are scheduled to take place on campus, it may be possible and/or necessary for some students to join these sessions remotely. Some of the listed contact hours may also be optional surgeries. Students will be provided with full information about the arrangements for all of these activities by the module staff at the beginning of the teaching semester.‘Independent online learning’ may involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or mini-projects, etc. Students will be expected to fully engage with all of these activities. The time commitment for independent online learning, and also the frequency and duration of online sessions are approximate and intended as a guide only. Further details will be confirmed when the module commences.Where assessments are shown as Online Time-Limited Assessments, the durations shown are indicative only. The actual time permitted for individual assessments will be confirmed prior to the assessments taking place.

Objectives

Electric machines play a principal role in our lives. They are electromechanical energy converters able to convert electric to mechanical power and vice versa. As generators, they produce almost all electric energy on Earth (conventional and renewable). As loads, they consume more than 60% of all electric energy produced with applications in transportation (e.g., electric vehicles, trains, personal electric transportation), in automation/robotics (linear and rotational movement), and in everyday life (fans, pumps, washing machines, etc). This module introduces students to the basic principles of electromechanical conversion and focuses on DC and AC electric machines. Students will gain an understanding of the operation of electric machines, starting from basic electromechanical conversion principles to their numerous applications and visiting different machine types. It provides students with the necessary skills to select and analyse appropriate electric machines for different applications.

Learning outcomes
On completion of this module students should be able to:

1. Explain the relationship between voltage, current, flux and EMF, and perform calculations with magnetic circuits.
2. Explain the physical principles of electromechanical energy conversion.
3. Describe the operation of DC machines in generator and motor applications, draw the equivalent circuits and perform calculations involving the speed, torque and power.
4. Describe the operation of AC machines in generator and motor applications and explain qualitatively and quantitatively the differences between synchronous and asynchronous AC machines, draw the equivalent circuits and perform calculations involving the speed, torque and power.
5. Provide application examples for different types of electric machines.

Private study

Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.



Opportunities for Formative Feedback

Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.
