Course responsible: Jagath Sri Lal Senanayaka, Petter Hieronymus Heyerdahl
ECTS credits: 10
Faculty: Faculty of Science and Technology
Teaching language: EN
(NO=norsk, EN=Engelsk)
Limits of class size:
Maximum 64 persons can have lab in January. See Norwegian text above.
Teaching exam periods:

This course starts in autumn parallel. This course has teaching/evaluation in autumn parallel and January-block.

See Norwegian text above on possible laboratory course in the June block. 

Course frequency: Annually.
First time: Study year 2010-2011
Preferential right:


1.            students who have the course as mandatory in their study plan

2.            students on the following study programmes:  B-EMF, M-MF, M-MPP, M-IØ, M-RB, M-LUR

3.            students with most ECTS credits

It there are not enough slots in group one the students will be ranked by their ECTS credits.

Students taking the course for the first time have lab priority.

Course contents:
The course starts out by repeating the electrical principles from the study of electromagnetism, relevant for this course. We will then cover the principles, construction, output, properties and fields of application of various electrical machines.
Learning outcome:
You will understand that all transformation of energy in machines follows the law of induction: Voltage is induced when an electrical conductor experiences a varying magnetic field. You will see that a dynamo, a generator, a motor, a transformer, a loudspeaker, a microphone, a cassette player and the read/write head in a computer disk are in theory similar machines. You will become familiar with some different machine types such as the induction machine also called asynchronous machine, the synchronous machine, the direct current generator and motor and transformers of various kinds. In the same way, you are to understand the difference between direct current, alternating current, single phase systems, three-phase systems and you will be able to conduct elementary calculations on machines in simple networks. You will also understand the ideas of efficiency, active and reactive power and some important roles that they play in small and large energy systems.
Learning activities:
Textbook teaching through lectures in the autumn parallell. Calculation exercises will be given throughout the course. Laboratory exercises in the January block  with labs on the most important machines and principles being part of the course.
Teaching support:
Canvas. Tutoring by teaching assistants. Meetings with teacher by appointment.
Theodore Wildi: Electrical Machines, Drives and Power Systems. Prentice hall, ISBN 0-13-093083-0 Currently: Sixth Edition. Curriculum is covered by chapters 1 - 18. Details will be given in Canvas. 7 laboratory assignments are also curriculum.

MATH111, MATH112, MATH113, FYS101, FYS102, FYS103,

It is advantageous to have some knowledge of electrical circuits as covered in FYS235 Electronics

Recommended prerequisites:
FYS235, FYS236
Mandatory activity:
There will be two midterm tests of seven quarters each. The first one is on direct current, DC, and will be held about week 40. The other one is on alternating current, AC, and will be held about week 46. You must pass both tests to take part in the laboratory part of the course. If you cannot participate in the tests, you must present a medical certificate. There will be no continuation tests for the two midterm tests. You have to participate in a safety demonstration and must in writing accept the safety instructions for the laboratory part before you can participate in the laboratory part. Alle laboratory exercises shall be performed and must, including reports, be approved before you can take the final exam.

Written exam. 3.5 hours. A-F. You will find more than 50 exams with detailed example solutions on Canvas. 

The exam will take place at the end of January for those who take the laboratory part in the January block. If there must be held laboratory in June, there will also be written exam after the lab period.

Nominal workload:
250 hours
Entrance requirements:
Special requirements in Science
Reduction of credits:
Type of course:

Autumn paralell: 2 hours twice a week. Exercises: 1-2 hours per week. January block: Laboratory assignments, duration 4 - 7 hours each.

Eventually June block: Laboratory assignments, duration 4 - 7 hours each.

The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate's exams as a calibration according to the Department's guidelines for examination markings.
Allowed examination aids: B1 Calculator handed out, no other aids
Examination details: One written test: Letter grades
