The goal Students are introduced to the function and importance of electric drives, types and structures, methods of analysis, synthesis and design of electrical drives. Attention is given to control of drives, and protection of people and equipment, an important issue in design, production and application of drives. Energy efficiency and environment protection in aspect of application and use of drives.
The outcome Students capable of independent: • Analysis of drive operation in stationary and transient regimes • Modeling of drives • Selection of components for drives • Design of drives • Application of drives
Contents
