Annotation The realization of typical electric drives for different essential groups of mechanisms: cranes, lifts, conveyers, pumps, compressors, funs, excavators and machine-tools. Calculation of the drives.The dynamic loads, transiert processes. Braking processes. Adjusting of effiency of the mechanisms, modes of automation systems and schemes for control of typical electrical drives.
Goals and objectives
of the course in terms
of competences and skills
The aim is to study mechanics of typical electric drive systems, influence of parameters on the drives characteristics, methods of speed control, calculation methods of transient processes, calculation of drives power parameters and motor selection for different operation regimes of typical electric drives. The students can describe and analyze systems of typical electric drives, select scheme for electric drive speed control and calculate elements of the schemes, calculate influence of transient processes on the operation of typical electric drives.
