Welcome to Electrical Machines and Drives at Dalarna University

The course is part of the bachelor's 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 met: Electrical Principles (introduction to simulation tool LT-SPICE ) and Electrical Power Engineering (electric and magnetic field, transformer, semiconductors, introduction to simulation tool Power Factory). If you do not meet these prerequisites, you are expected to bridge the knowledge gaps in advance or at the latest before the relevant parts of the course.

You can follow this course live on campus, live online via Zoom or by watching recorded lectures. 
Campus: The main classroom will be the Power Lab B423, located on 4th floor. Please check the map for the location and test your access to the floor before course starts. Note that you can only use the doors in the first and second floor to enter the staircase leading to the 4th floor. Your keycard needs special access for Energy students. If you do not have this access, please kindly visit the reception to have it added to your keycard. Note that some study activities are conducted purely online. Computer rooms with the necessary software are available on campus. 
Zoom: The classroom and Zoom room are visible in your personal schedule in Student Web when you log in with your student account. One exception is Sarah's workshops; she will post the Zoom meeting in Canvas. When attending via Zoom, please make sure that you have working audio and video, and that you are logged in with your student account using SSO. Check the webpage Study tools if you are unsure how to log in to Zoom. 
Recorded lectures: Recordings will be uploaded within 24 hours from the lecture. After that, you can send a reminder if a recording has not been for uploaded. 

What you will study

In this course, you will explore systems for electromagnetic energy conversion, with a major focus 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, online via Zoom or watch uploaded recorded lectures with some delay. 

Own work
The own work material is provided via Canvas; it may be pre-recorded lectures, reading material or other media. Own work material needs to be prepared before the module question session. The own work time is scheduled in TimeEdit to clarify which material is expected to be prepared before each question session.

Question Sessions
The question session is your time ton discuss open questions from the study material with other students and the teacher. It is only effective if you prepare properly beforehand and attend the session so that you can ask questions. If you cannot attend, please send your questions in good time, either in written form or as a short recording.

Course accompanying assessment (Canvas Submission/ Quiz, Wooclap Quiz or Padlet)
Since this course has no final written exam in a classroom, it is obligatory to complete all quizzes and tasks that are given. We strongly recommend to conducting accompanying assessments before the start of next module or the given deadline. Please note it is requires that you log in to Wooclap and Padlet with your university Microsoft account.

Laboratories
You will conduct two laboratories: one focuses on machines and the other on drives.
In the electrical machine laboratory, you will attend either a) the DC machine, b) the induction machine, or c) the synchronous machine laboratory. After the laboratory you will prepare with your group a presentation on your machine that you will present at the seminar. The drive laboratory will be performed by all students. Laboratories have obligatory attendance in Borlänge and can only be conducted once a year. TimeEdit shows the schedule for laboratories; please register for the labs. You will find the link below in the fast overview table. For distance students, please organize your train tickets and accommodation in advance and try to finish as many group tasks as possible during your stay in Borlänge to avoid group communication issues.
Prerequisites for attending the Elaboration: You must have submitted all individual tasks that have a due date before the elaboration week. (Any exceptions to this prerequisite must be discussed with the course coordinator well in advance.)

Study visit
We will visit a  hydro power station to look at its electrical machines.

Project
You work in a group of 2-3 people on a chosen application. Here you have to select the electrical machine and drive system and argue which is the most suitable machine and explain why the other machines are not suitable for your specific application. The work is examined through an oral presentation and a written report at the end of the course. Grouping should be done one week before the laboratory visit so that you meet once physically and can discuss your application. 
Prerequisites for attending the Project: You must have submitted all individual tasks that have a due date before the elaboration week. (Any exceptions to this prerequisite must be discussed with the course coordinator well in advance.)

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.
A workshop is given on presentation technique as a support for you during the project.  A librarian will introduce you to the reference management tool Zotero, which you are expected to use during the project. 

Plagiarism and Other Academic Misconduct
Plagiarism means presenting the content of someone else's work 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 your examination. 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.

Course evaluation
In this course, you will be asked at the end of the course to give your feedback during the physical compulsory meeting. We are also very happy to receive any feedback during the course, in the classroom, via email or in any other form. Any feedback is systematically analyzed and conclusions and actions are described in the teacher’s course evaluation.
