Module summary

The teaching and assessment methods shown below will be kept under review during 2020-21. 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) the Online Learning Workshops. For Semester 2 (from January 2021), we anticipate that this will be most likely, in which case online teaching will be substituted for traditional face-to-face teaching methods, including lectures and practical classes. ‘Independent online learning’ will involve watching pre-recorded lecture material or screen-casts, engaging in learning activities such as online worked examples or remote/virtual laboratory work, 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 Learning Workshops, are approximate and intended as a guide only. Further details will be confirmed when the module commences." "The teaching and assessment methods shown below will be kept under review during 2020-21.

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 the most common devices that an electrical engineer will encounter: DC and AC electric machines.

Objectives: This module gives students 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, size, and analyse appropriate electric machines for various applications."

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

1. Understand and explain the basic relationships between voltage, current, flux, and EMF; perform computations with simple magnetic circuits; understand and explain the basic principles behind electromechanical energy conversion.
2. Understand the operation of DC machines both in generator and motor operation; draw the equivalent circuits and perform basic calculations concerning the speed, torque, power, etc; be able to analyse their steady-state behaviour and estimate parameters.
3. Understand the operation of AC machines both in generator and motor operation; be able to explain qualitatively and quantitatively the differences between synchronous and asynchronous AC machines; draw the equivalent circuits and perform basic calculations concerning the speed, torque, power, etc; be able to analyse their steady-state behaviour and estimate parameters.
4. Provide application examples for different types of electric machines.

Syllabus

Topics may include, but are not limited to:

Magnetic circuits and magnetic materials

Private study

Students are expected to use private study time to consolidate the material covered in lectures, to undertake preparatory work for examples classes/laboratory classes and to prepare for summative assessments.

Opportunities for Formative Feedback

Formative feedback will mainly be through the worked examples that students will undertake in the example classes
