Topic outline

  • General

    This course is intended as a first course on electric motor drives. The basics of mechanics as well as selection of components (motor and converter) are covered. During the course, modelling and control concepts are introduced using a DC motor and a surface-mounted permanent-magnet synchronous motor (SPM) as example machines. Other AC machine types are briefly discussed at the end of the course. Operating principles of a four-quadrant DC-DC converter and its pulse-width modulation are described in more detail, while three-phase converters are mainly left out of the scope of this course.

      Exam: 15th December 2021, 9:00 - 12:00 Quiz

      The exam will be held digitally here on 15th December 2021. The exam will start at 9:00 and end at 12:00.

      • You will need your computer with internet connection, pen, paper, and mobile phone to solve the problems and submit your answers.
      • The digital exam aims to be aligned with the learning outcomes of the whole course and the individual learning outcomes of each lecture (and exercise). You can use course materials, calculator, computer, and internet.
      • You are NOT allowed to ask help from others.
      • The structure of the exam will be like the structure of the paper exams from earlier years (with some minor changes). This year you can use materials. Therefore, the problems will be such that you must process information more as compared to the earlier years. In other words, the exam aims to test if you have understood the concept, instead of testing if you are able to find it from the materials.
      • You can copy-paste relevant figures and equations from the course materials to your answers. However, avoid copy-pasting unnecessary or irrelevant material.
      • In some problems, you may be asked to attach some drawings or equations. You can simply use pen and paper for this purpose. Then, take a photo of your hand-written solution with your mobile phone and attach it to your solution. (Alternatively, you may use digital tools such as an equation editor or a drawing program, which, however, can be more time consuming. Or if you feel it easier, you can use pen and paper for all your answers.)
      • In your attachments, allowed file formats are pdf, jpg, png, and svg. You can submit your solutions as a single document, or you can submit several separate files.
      • Before the exam, please practice how to get photos from your mobile phone to your computer.
