Course detail

Electrical drives

FEKT-CEPBAcad. year: 2010/2011

This new course link to courses of mechanic, theory of Electric machines and Power Electronics. Explain the principles and methods dimensioning of power parts structure of Electric drives. Electric drives play an important role as electromechanical energy converters in most production processes.Explain problems : Dynamics of a Mechanical Drive,
Integration of the simplified Equation of Motion, Thermal effects in Electrical machines,structures with Separately Excited and Series DC machines, Control of Converter-supplied this type,Induction Motor + frequency converter,Variable Frequency Synchronous Motor Drives and Some Applications of Controlled Drives.
