Vliv charakteristik elektrických motorů na dynamické chování poháněných soustav
Půst, Ladislav
The more precise mathematical models of dynamic systems must contain also more exact description of source of excitations. The paper deals with the analysis of electric motors characteristics and of interaction of motor with limited driving power and excited system. The moment charcteristic M(xxx) of the motor introduces new nonlinear effcts into the whole system and causes more complicated responses.
Identification of impacts in drive systems
Kratochvíl, Ctirad ; Grepl, Robert
In the last few years apears the existence of problems by controled drive systems because of impacts. Directly in mechanical constraints and also in control subsystems. Conditions of its existence where study mostly for systems with 1 or 2 DOF.
The Compare of Dynamic Properties of Electromechanical Drive Systems with
Kratochvíl, Ctirad ; Procházka, František ; Pulkrábek, J.
DC drives are more and more used drives in engineering for both high and low powers. In examination of its dynamic properties one must consider both disturbances of drives themselves and its control and possible disturbances in gears.
