Název v původním jazyce
Modelling and analysis of dynamics of electric motor rotor
Popis výsledku v původním jazyce
This paper deals with the dynamic modelling of electromotor. The models are characterized by flexible shaft with mounted packet of sheet metals that are equipped with parallel copper bars connected by end shortcircuit rings. Finite element analysis in rotating coordinate system is used for the discretization of the shaft, while the sheet metal packet of cylindrical shape is modelled as a set of rigid bodies joined using chosen viscoelastic forces and torques. The shortcircuit rings are supposed to be rigid in the basic dynamic model and the pieces of copper bars are substituted by massless springs of calculated properties. These parts are considered to be flexible in the second complex dynamic model. Problematic model parameters are identified by meansof performed experimental measurements of modal analysis.
