Analytical-computational approach to dynamic investigation of the electro-mechanical coupling effects in the rotating systems driven by asynchronous motors

In the paper dynamic electromechanical interaction between the rotating machine drive system and the electric driving motor is considered. The investigations are performed by means of the circuit model of the asynchronous motor as well as using an advanced structural hybrid model of the drive system. The results determined for harmonic excitation generated by the driven machine working tool are qualitatively analysed from the viewpoint of influence of the electromagnetic stiffness and damping between the stator and the rotor on dynamic properties of the mechanical system.
