- No, not at all. This course want to explore the world of motors and generators and due to vastness of the world, it can not do anything. It should have been more focused.» (No, the goals are set too high)

- The turtorials could me more organized..» (Some extent)
- Good teaching in lectures, not as good in tutorials.» (Large extent)

Genomsnitt: 2.78

- Very shallow. The course just touched every subject but with no detail.» (Much too shallow)
- it was a too bright range that was tried to cover, would have been better to do less and to go in deeper» (Much too shallow)
- i was expecting this cource to deal with methods to control electrical motors, but the cource was mainly about the machine itself and that part in my openion was not treated with the expected depth, i think it would have been better if the kinds of machines treated in the cource were limited to the conventional types and handeled with more careful detailed study insted of dealing with a various kinds of machines without going deep enough in staudying any of them.» (Somewhat too shallow)
- Well, I do believe it is better to give much details for the classical Machines like Induction and Synchronous and even it would be better to change the name of the course to Elect.Machines instead of Elect.Drives and devote the second course to Elect.Drives after taking the necessary dose of Power Electronics, otherwise the course will be something in between.» (Somewhat too shallow)
- of course due to time shortage much in detail is not discussed in the class.» (Adequate)
- Some parts where too deep compared to others.» (Somewhat too deep)

- Not unusual to have the tutorial immediately after the lecture.» (Little extent)
- Nearly no time. We were at the classes all the time and did not have any time to prepare for tutorials.» (Little extent)
- I think it would be better if the tutorial papers where put on the web 1 or 2 days before the tutorials. Then you could tackle the exercises on your own and then see how to do it in class if you have problems. » (Little extent)
- The tutorials were too closed lecture. We had no time to prepare ourself for the tutorials.» (Little extent)
- sometimes tutorials are solved soon after the lecture class» (Little extent)
- this was not good! Directly after a class the tutorial is of little help, mostly it is just a time for copying the blackboard. so the tutorial could be efter a day or like a 2 hour free time to look into the material. otherwise I em not following and I feel the time is wasted.» (Little extent)

- not poroer way of using math, no derivatons, highly simplified formulars / relatation (sometimes you cannot even say a formula was offered) that ony fit in special cases» (Some extent)
- There were few questions in tutorial, and I believe it was because of the short time between lecture and tutorial. The questions come after you sit for yourself and try to solve the problems.» (Large extent)

- The book was more oriented to discussion which was good. » (Large extent)
- 70% was close to the book» (Large extent)
- I often miss things and therefore need to be able to learn myself. The book was really good but we never got any answers to those tutorials that was connected to subjects outside that book. Made it impossible for me to catch up!» (Great extent)

- Having to write a report made it necessary to get into it. So it was good.» (Large extent)

Genomsnitt: 2.3

- I think the labs were so so useful but the report writing I think was just wasting time. SUGGESTION: Give us some forms to fill in our results and short questions.» (Small extent)
- I do prefer that there will be no lab report and instead the students should prepare themself well before the labs by doing the assignments and before starting the labs the assistant should assess the knowledge of the students by asking some questions and based on that he can decide wheather the student is ready to carry out the experiment or not.Also after the end of each lab the assistant should discuss the results with the students and give the necessary comments.I think this will be more helpful. Other things the number of the assistants are quite small compared with the number of the groups» (Small extent)
- took to much time» (Some extent)
- When you write the report you already know all the answers to the questions so there is just waste of time for my learning to write a report on all the labs. This time that I spent could be used for further reading etc. A report on the computerlab was though good, because it lead to deeper understanding.» (Some extent)
- see above» (Large extent)
- it is good to write things on your own, but takes a lot of time, especialy working on the report with others» (Large extent)

- You have such a nice system with the schedule in the student portalen. Why you don"t use it?» (Very badly)
- How about putting some solutions and not only answers on the course page more sooner.» (Rather badly)
- Solutions to tutorials took several weeks to appear on the web page» (Rather badly)
- Only because of the tutorials. The questions with solutions should be on the homepage after the tutorial. How should be otherwise be able to lurn things?!» (Rather badly)
- Our printer quotas are not adjusted so that we can print the slides ourselves.. so to have them handed out before every lecture should be obvious!» (Rather badly)
- Except for what I mentioned in question 14» (Rather well)
- Please use Time Edit next year and keep it updated. There is no reaon not to use it.» (Rather well)
- But I think the tutorials should be on the web page alot sooner so you can look at them before the utorial and start to think about the questions. And then It should be posted on the web page if the lecture had had any handouts that day, so if youre sick or something, you know that there is something you should try to get. » (Rather well)
- need some handouts» (Rather well)
- The webpage and especially its handouts section was extremely good. Keep up the good work. Really useful...» (Very well)

- It was so many pages to read... it felt like I never would pass them!» (High)
