Goals and objectives
of the course in terms
of competences and skills
|Main target is to acquaint students with the general knowledges of application of electrical drives, electrical machines, power electronics in electrical transport national economy systems. Student must be able apply predominatory knowledges for simplified calculation of motion, electromechanical and energetic characteristics of electrical transport.|
To be able classify electrical transport traction drives in respect to properties of power supply and electrical motors - Succesful passing of test negotations
To be able explain a motion regimes, apply equations for calculation of motion processes as also energetic connections - Qualitative elaboration of the anticipated 3 home works for admittance of the test lesson and succesful passing of test negotations
