The results of the development of a mathematical model of a synchronous motor and a study of the influence of the degree of saturation of the magnetic circuit on the transient processes of direct start-up are presented. It is noted that the existing methods of research and calculation of transient processes of synchronous machines are based on the application of the superposition (superposition) method, which excludes their use in nonlinear systems.

As a result of the analysis, ways to reduce electricity losses in the system of its production, distribution, transmission and consumption in industrial enterprises have been identified. The problem of recompense of jet capacity always occupied the important Place in the general complex problems of increasing transfer efficiency, distribution and consumption of electric energy. The correct decision such problems appreciably predetermines economy monetary and material resources, electrical supply improvement of quality. The main recompense problems of jet capacity should be considered with the account of modern views and taking into account new technical decisions in this area. The analysis of electricity losses in the Republic and increasing their energy efficiency while optimizing the consumption of reactive power is made. Recommendations have been developed to reduce losses on the line and in-plant losses of electricity.

In order to conduct model experimental studies of the mutual influence of electromagnetic and mechanical transient processes of starting up inertial vibration drives with an asynchronous motor, its mathematical model is being developed. The analytical dependence of the dynamic mechanical characteristics of the vibrator at various values of the rotor acceleration is determined. The mathematical model uses the dynamic mechanical characteristics of an induction motor as a torque.
