The article covers issues related to the ways of improvement an asynchronous engine. The features of modernization of asynchronous motors aimed at increasing their energy efficiency are considered. The reasons for the low average load of this engine in the electric drive, especially the traditional and the newest approaches to the calculation of such engines, are analyzed. A new method of executing a stator winding (combined windings) of an electric motor, which has a significant economic effect, is characterized. It is noted that this method of performing the stator winding provides: the ability to adjust the speed at a constant current frequency by gradually changing the voltage throughout the speed range; soft and stable mechanical characteristics; consumption of smaller starting currents and increase of a twisting moment; improvement of vibration and noise characteristics. The importance and peculiarities of studying the methods of increasing the energy efficiency of asynchronous engines by future teachers is substantiated. In this context, the study of improving the efficiency of electrical installations, in particular induction motors, is important in the formation of professional competencies of teachers related to the ability to analyze and evaluate objects of the technological environment and the ability to organize research activities of students in the process of working on educational projects. .

This article takes the sizing 195/65R15 as an example and establishes a 3D tire FE model to simulate the tire in the steady rolling process through Pro/E and Abaqus software. The vibration accelerations of nodes were extracted from tire surface, which can be transferred into acoustic boundary conditions to calculate the tire vibration noise by acoustic finite element method and acoustic infinite element method. This paper provides a new method which calculates the tire vibration noise and predicts the tire noise characteristics in the conceptual design phase.

Channel Control

Constantly increasing requirements for the performance of electromechanical systems include the task of improving the vibration and noise characteristics of the electric drive. Currently, this problem is solved mainly by using traditional three-phase systems. The transition to a multiphase version of the electric drive construction opens up new opportunities for its solution. The aim of the study is to improve the vibration and noise characteristics of the electric drive through the development of a multiphase control system that provides targeted formation of the field configuration in the gap of a multiphase electric machine. To conduct the research, the model of a multiphase synchronous motor proposed by the authors was used. The model considers the spatial non-sinusoidality of the field distribution in the gap and enables to represent the engine as a set of parallel substructures, the number of which depends on the number of phases. The technique to design a synchronous motor with an arbitrary number of winding phases based on the field model of the machine has been proposed. The correctness of the results obtained is ensured by the real geometry of the magnetic circuit and steel saturation. The multi-channel control system of the electric drive, characterized by the targeted formation of field configuration in the gap of a multiphase electric machine has been proposed. The calculation model of the electric drive has been developed. The model combines the field model of the engine and the control system. The engine model is implemented in the ElСut software package, the control system model is implemented in the MatLab (Simulink) complex. Compared to the traditional three-phase design of the electric drive with a sinusoidal supply voltage, the options for forming a field in the gap of a synchronous motor considered in the article provide a reduction in ponderomotive force by 8–14 %. The engineering methodology for designing an m-phase synchronous permanent magnet motor with permanent magnets and the structure of the multi-channel control system can be applied when developing electric drives with improved vibration and noise characteristics.

Vibration Noise

Vibrations and noises occur during the operation of synchronous motors. To reduce them, more advanced engine designs and special control algorithms are used. The application of a multiphase (m > 3) synchronous motor design allows you to influence the configuration of the magnetic field in a wider range. Thus, the task to develop a control algorithm that improves the vibration-noise characteristics of a multiphase motor is relevant. The finite element method is used to calculate the magnetic field in a 2D formulation, implemented in the Elcut software package. Also, the simulation methods with the MatLab Simulink package are applied. The authors suggest the algorithm to control multiphase synchronous motors with permanent magnets that reduces the level of vibrations. Improvement of vibration-noise characteristics is achieved when the motor is supplied with currents of the certain form, and they compensate the pulsation of electromagnetic forces that occur between various parts of the electric machine. This algorithm is based on the measurement of the electromagnetic forces and the torque directly in the process of control. The results of modeling the operation of the engine with the developed control algorithm are presented. The authors have compared the characteristics obtained using the developed control algorithm and the characteristics that correspond to the sinusoidal source supply. The vibration-noise characteristics of a permanent magnet synchronous motor can be improved by using the control system. This control system generates currents in an appropriately synthesized form. In this case, the power consumption will increase slightly.
