Goals

Explain the working principles of electric machines, construction elements and operating states. Explain the basic analysis of individual electrical machines in different working regimes. Explain the basic state diagnostic procedures and condition monitoring of electrical machines implemented in electrical drives. Train students to conduct simple calculations and analyses of basic electrical machine parameters for different load conditions of asynchronous, DC and synchronous machines. Train them to conduct measuring and testing procedures for synchronous and DC motors, synchronous and DC generators. Train students to conduct calculations of all values obtained by these measurements and to analyse them.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. explain the working principles, construction parts, the role of transformers in the electric power system, and identify the basic operating states (no load, short circuit, operation under load)

2. explain the working principles, construction parts, role of DC, asynchronous and synchronous machines and drives. Identify the basic operating states (no load, short circuit, operation under load)

3. evaluate the procedures for status diagnostics and results of monitoring the operation of electrical machines in plants

4. explain the calculated values for voltages, currents, power and efficiency for different loads of asynchronous, DC and synchronous machines

5. critically analyse solutions obtained for selected numerical examples of electrical machines

6. categorise and differentiate measurement and testing procedures of asynchronous and DC motors, synchronous and DC generators as well as explain and analyse calculated sizes obtained by these measurements
