The study centers on dynamic transients resulting from jump-like changes in controller of machinery electrical drive. Discussion requires description of dynamic processes in various operation modes-acceleration, deceleration, reversing, and transition between different angular velocities given DC and AC engines momentums conditioned on angular velocity values. Conditions in which technological drives operate necessitate relevant transient modes aiming either to provide for maximization of operation speeds, or minimization of losses, or limitation of dynamic loads generated in components of kinematic chains which link electric drive and working element, etc. Control of transient processes in the electric drive guarantees maximum operation speeds and equipment performance given specific limitations. On the basis of the dynamic drive model with two degrees of freedom, the different stages of the run-up mode were analyzed. The characteristics of the static component of torque on the shaft in steady mode and the dynamic component caused by the transient process are determined. The ways of reduction of the dynamic component significant for the drive operation are offered.

The determination of equivalent circuit parameters for AC induction motors represents an important task in an electrical machine laboratory. Frequently used open-circuit and short current tests answer these requirements. However, the results have a low accuracy. This becomes especially obvious when the equivalent circuit is applied for the motor current and power prediction. The main obstacles in this circumstance lie in the difficulty of providing a pristine open-circuit test, the lack of which causes errors in parameter estimation. A much more accurate approach can be carried out with a test including several output points with measurements of the motor torque, velocity, current, and power magnitudes. Nevertheless, a relatively simple and accurate method to ensure determining parameters for such tests does not exist. This article tries to provide such a method by an approach based on Kloss’s simplified equation and the Thevenin theorem. The significant novelty of the method is the specially selected synergetic interaction between the analytical and numerical approaches, which give a relatively simple algorithm with a good accuracy and a convergence of the parameters’ estimation.
