Abstract
The problem of improving the calculations for the dynamic modes of the electric drives is considered. The procedure of analytical replacement of multimass systems of mechanical systems with equivalent two- or three-mass systems is described, when it is envisaged that the records contain the moments of inertia and stiffnesses of transfer ratio shafts that are considered constant at all stages of the subsequent calculations. In high dynamic modes of operation of the drive, this constancy is violated. It is proposed to consider the mechanical part of the electric drive as a set of rotating masses without using the ideology of adjusting the moments of inertia of the rotating masses, the stiffnesses of the shafts, etc. with a purpose of clarifying the operational loading of the components of the electric drive.
