Learning activities and teaching methods
Activating (Simulation, games, dramatization), Exercises on PC
  • Preparation for examination - 15 hours per semester
  • Home preparation for classes - 10 hours per semester
Learning outcomes
The subject aim is to introduce the students of engineer study to the basic electromechanical energy transducers (motors electric) principles and realization techniqueas as a part of actuating device for mechanical systems motion control
Graduate of this course should know to describe behaviour dynamic of separate elektro- mechanical transducers- el .machine that way, to enabled to him to project and eventually realize their control as the actuator for mechanical movements control.
Prerequisites
Prerequisite is linear algebra, differential and integral calculi of several variables and ordinary differential equation systems knowledge. Next, the theoretic electrotechnics (dynamic states in el. network). Physics within the range of BC studies on technical university knowledge.

Assessment methods and criteria
Composite examination (Written part + oral part)

80% students' attendance on practices and seminars. Complete the scriptural examination within the time range of 1.5 period.The result of a subject examination is expressed on a six-point scale: A "výborně" (i.e. "excellent"), B "velmi dobře" (i.e. "very good"), C "dobře" (i.e. "good"), D "uspokojivě" (i.e. "satisfactory"), E "dostatečně" (i.e. "sufficient"), F "nedostatečně" (i.e. "fail").
