Mathematical Modeling of Mechanical Characteristics of Transient Processes of Asynchronous Electrical Drives of Weaving Machines in Textile Enterprises
Abstract
Asynchronous electric motors are widely used in industrial electric drives, including textile enterprises, where their operating efficiency and dynamic characteristics directly affect the energy consumption and productivity of technological equipment. Therefore, accurate mathematical modeling of asynchronous motors is important for analyzing transient operating conditions, determining their electromagnetic and mechanical characteristics, and improving the efficiency of industrial electric drive systems. The purpose of this study is to develop a mathematical model of the 4A100L6U3 squirrel-cage asynchronous electric motor and investigate its dynamic and mechanical characteristics during the starting process. A three-phase asynchronous motor with a rated power of 2.2 kW, supply voltage of 220/380 V, and nominal rotational speed of 950 rpm was selected as the research object. A mathematical model of the motor was developed to describe its electromagnetic and mechanical behavior. Based on the developed model, transient processes occurring during motor starting were simulated and analyzed. The changes in the main electromagnetic and mechanical parameters were investigated, and the mechanical characteristic of the asynchronous electric drive was constructed. Particular attention was given to the starting torque, critical torque, nominal torque, and slip characteristics. The simulation results demonstrate the dynamic behavior of the 4A100L6U3 asynchronous motor during the starting process and provide a basis for evaluating its operating characteristics under industrial conditions. The obtained mechanical characteristic and analyzed torque and slip parameters allow the main operating regimes of the electric drive to be assessed and optimized. The results of the study can be used to improve the energy efficiency and reliability of electric drives in textile enterprises, optimize the operating modes of technological equipment, and improve the control and regulation systems of asynchronous electric motors
