Opis:: The operating modes of the automatic control system for electromechanical converters for synchronization of rotor speeds have been developed and investigated. The proposed automatic speed control system allows adjusting the slave engine to the master one in a wide range from 0 to 6000 rpm. To improve the synchronization accuracy an adaptive algorithm is proposed that allows to increase the synchronization accuracy by 3-4 times. The proposed model of an adaptive automatic control system with an observing identification tool makes it possible to minimize the error in the asynchrony of the rotation of the rotors of two electromechanical converters.

Opis:: The paper has dealt with two theoretical problems of calculation of electromagnetic force or torque. The first problem considers the magnetically anisotropic and conductive region. The theorem about equivalence of both Maxwell and Lorentz methods has been presented. The second problem deals with the independence from the integration surface of force or torque calculated by the Maxwell method. The second theorem which presents the sufficient condition for an independence problem in the anisotropic and nonconductive region has been formulated.

Opis:: The purpose of that paper is to develop of unified equations of electromechanical energy converters accounting for the magnetic non-linearity of the main magnetic circuit of a converter. The concept of applying higher order forms of winding currents for the description of the co-energy function is introduced in order to derive the structure of converter equations via mathematical analysis. Also, another concept of equivalent magnetizing currents is applied to determine the higher order forms for selected converters designs. The structure of circuital equations for converters with multiple windings has been unified by means of the introduction of matrices of dynamic and nonlinear inductances following the higher order forms of the co-energy function.

Opis:: This paper describes DC drive with thyristor voltage regulator Lenze 530 series. To investigate the transients of the drive system developed numerical model in MatLab is developed. Dual circuit structural diagram of “TCV-DC motor” system with negative feedback for the current and angular speed or current and armature voltage in model is realized. By introduction of current feedback, torque and current limit are achieved and with using of armature voltage or tacho automatic speed stabilization is obtained. At this model certain standard settings of cascade control system are made. The basis of the internal loop consist from PI-regulator with KP.C=2 and KI.C=100 gains, TCV and armature transfer functions, covered by armature current feedback. Current controller is configured at technical optimum. Second circuit can have armature voltage feedback; can be tuned at technical optimum and has a P-regulator with KP.S=36 gain. In same way it can have a speed negative feedback with the same tunings. A numerical model has restrictive blocks: to limit the maximum and minimum speed and maximum current. To demonstrate the obtained results virtual oscilloscopes were used. Also the electromechanical characteristics of the drive with armature voltage and current or speed and current feedbacks using XYGraph block are presented. At this paper the electromechanical characteristic of the real DC drive Lenze 530 series is presented too. According to research results at numerical model and physical investigation equipment graphs of instantaneous values of current and electromechanical characteristics are made. Analysis of graphs confirms the adequacy of the results obtained at the numerical model and the real drive system, which enables the use of the developed numerical model for the investigation of similar DC drives. DC drive model with thyristor voltage regulator Lenze 534 and results of investigations of electromechanical properties are presented.
