DYNAMIC INVESTIGATIONS OF ELECTROMECHANICAL COUPLING EFFECTS IN THE MECHANISM DRIVEN BY THE STEPPING MOTOR

Inthepaper,ananalysisoftransientandsteady-stateelectro-mechanical vibrationsofaprecisedrivesystemdrivenbyasteppingmotorisperformed. These theoretical investigations are based on a hybridstructural modelofthemechanicalsystemaswellasontheclassicalcircuitmodel of the stepping motor.The mainpurpose ofthese studies is toindicate essential differences between the torsional dynamic responses obtained for the considered object regarded respectively as electro-mechanically coupledand uncoupled.Fromthe computationalresults,it followsthat these differences are qualitatively and quantitatively essential from the viewpointofpossiblypreciseandreliableoperationofthedrivesystems. Here,torsionalvibrationsofthedrivesystemsignificantlyinfluencethe electro-mechanical coupling effects, which emphasizes their importance indynamicanalyses.
