Course syllabus
Welcome to Electrical Machines and Drives at Dalarna University
The course is part of the bachelor program in Energy Technology and takes place in the third period of the second year. You can also attend the course as an exchange student or as an independent student. The following entry requirements should be meet: Electrical principles, Electrical Power engineering (electric and magnetic field, transformer, semiconductors, Simulations tools LT-SPICE or Power Factory).
What you will study
In this course, you will explore systems for electromagnetic energy conversion, where the major focus is on electrical machines and drive systems. Theoretical concepts of various electrical machines and drive systems are covered:
- DC machines
- induction machines
- synchronous machines,
- machines with permanent magnets,
- power semiconductors,
- pulse width modulation
- direct current and alternating current conversion
Additionally, students will learn how control strategies in drive systems can contribute to the electricity grid.
This course should give you a good base for the coming courses Automation and Control Engineering (only in Swedish), Renewable Energy Technology, Combined heat and power systems and Active Electric Networks
Learning activities
Lectures
You can attend lectures live on campus or online via Zoom or watch with some delay uploaded recorded lecture. You can find the Course schedule in TimeEdit, here you also find the classroom and zoom room link. If you attend via Zoom please login via SSO to Zoom. You don't know how to do this: Check out the webpage Study tools.
Own work
The Own work material is provided via Canvas, it could be pre-recorded lectures, reading material or other media. Own work material needs to be read or prepared before the module question session. The own work time is scheduled in TimeEdit to make clear before which question session material needs to be prepared.
Question Sessions
The question session is your time where you can discuss open questions from the study material with other students and the teacher. It is only effective if you prepare yourself properly before and attend this session to be able to ask questions. If you can’t attend please send your questions either in written form or in a short recording.
Course accompanying assessment (Canvas Submission/ Quiz, Wooclap Quiz or Padlet)
Since this course has no final written exam. Is it obligatory to do all Quizzes and task which are normally given in the lectures and own work material before the new module starts. This requires that you login to Wooclap and Padlet with your university Microsoft account.
Laboratories
You will conduct two laboratories on has its focus on machines the other on drives. In the electrical machine laboratory, you will attend either a) DC machine, b) Induction machine or c) Synchronous machine laboratory. After the laboratory you prepare with your group a presentation on your machine that you present at the seminar. The drive laboratory all students will perform. Laboratories have obligatory attendance in Borlänge. TimeEdit shows when campus and distance students are scheduled for laboratories. For distance students please organize your accommodation in advance and try to finish as many group tasks as possible during your stay in Borlänge to avoid group communication issues.
Study visit
We will visit one of the hydro power stations in Borlänge to look at their electrical machines. Until then you should know which electrical machine is used in hydro power stations.
Project
You choose an application where you have to select the electrical machine and drive system and argue why other machines are not suitable for your application. The work is orally presented at the end of the course.
Academic Writing
When writing an academic text or preparing a presentation, it is important to reference the sources you use so that it is clear where you have obtained your information and what is your own reasoning and what belongs to others. If you use someone else's work without referencing the source, you risk committing plagiarism. In this course you should use IEEE citation style.
If you need help with information searching, reference management, or other questions, you can book an appointment with a librarian.
Plagiarism and Other Academic Misconduct
Plagiarism means presenting the content of someone else's as your own. Plagiarizing is considered a violation of good academic practice and can lead to suspension from your studies. To avoid plagiarism, it is important to learn how to reference, quote, and cite correctly when using other people's content.
Always carefully read the rules that apply to each exam, for example, regarding whether collaboration is allowed or which aids may be used during a written exam.
By submitting an assignment, you confirm that you have read and understood the rules regarding academic misconduct and plagiarism.
Any suspicion of misconduct will be reported to the rector. For more information, please refer to the student portal.
Coures evaluation
This course is entirely new. Therefore, is your feedback very important for us and we encourage you to share your comments and suggestions with us. In this course, you will be asked by the end of the course to give your feedback in an online session. We are also very happy for any feedback during the course, in the classroom, via email or any other form. Any feedback is systematically analyzed and conclusions and actions are described in the teacher’s course evaluation, which we will be shared with the students in the course room.

Re-examination Project |
If you couldn't start the project during week 11 and 12 and you would like to do the project during the summer please fill out when you are available. I would prefer if we could agree on one presentation time to enable a good discussion around the topics during the presentation day. If only one group is presenting than there is not much of discussion. |
Re-examination - Project work during summer fill the poll in the page. Thanks |
