Content

This subject is about the structure, functions and characteristics of static and rotating electrical machines. The student must acquire knowledge about the structure of electrical machines and their importance for electricity production and distribution and their importance for the use of electrical energy to carry out work in industry. The course also provides an introduction to the production of electrical energy from water, wind, thermal power and the sun, as well as the importance of production technology for the function and characteristics of the power grid.

Learning outcome

  • Have knowledge of the production of electrical energy from water, wind, thermal power and the sun.
  • Have knowledge of synchronous generators, transformers, 3-phase distribution and autotransformers, DC generators and DC motors, induction machines (asynchronous machines), and synchronous machines.
  • Know converter technology, rectifiers and inverters, and be able to describe function, use and connection.
  • Have knowledge of modern electric motors and associated converters for use with DC voltages, including PMSM and BLDC.
  • Be able to understand and explain concepts such as commutation, efficiency, mechanical and electrical losses.
  • Have knowledge of lifetime estimation, fault situations, malfunctions and typical forms of machine failure on electrical transformers, motors and converters.
  • Understand the need for protection of motors when using motor guards.

Course assessment

There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
