Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After the course, students will be able to:
1) describe typical applications of electric drives and their performance requirements;
2) calculate the required electromagnetic torque of the motor for various mechanical loads;
3) build simulation models for cascade-controlled DC motor drives and scalar-controlled induction motor drives;
4) tune a PI speed controller based on the mechanical parameters;
5) select the motor and the converter for simple applications.
