Course work and exam formalities

written exam at the end of the module, 60 minutes


Position dependent inductances, space vector description of electrical machines: fundamental wave and harmonic waves, force and torque calculation: fundamental torque and harmonic torque and harmonic torques, laws of growth and scalability;

General performance of electrical machines: rotating field machines (induction machine and electrically excited synchronous machine), synchronous and asynchronous torques, windings: distributed windings and concentrated windings, permanent magnet excitation in electrical machines

Learning outcome

By taking part in module, the students gain deepend knowing in the physical mode of operation and formation of torque in electromechanic converters. In addition, students learn to apply the achieved basic knowledge about electrical machines on particular types of machines and describe the operating behaviour of these types of machines mathematically.

Teaching and studying methods

Additionally to the individual learning methods of the students a more detailed knowledge development is assured by several tutorials, where problems are discussed and individually solved.

As teaching method during lecture and tutorials classrom teaching is preferred. During tutorials also problems and exercises are provided (discussion, evalution and analysis of e.g. simulation examples, solution statements,....).
