Study of the dynamics of the working parts of a controllable electrical complex for production of chemical fibres and nonwovens

A nonlinear system of algebraic and differential equations was obtained that can be used to study a complex electromechanical system with consideration of the statistical characteristics of the working parts, the electromagnetic processes in the electric drive, and the effect of flexible couplings in kinematic transmission. Calculation of the system of equations obtained showed that in transition regimes, important errors in the linear velocities of the working parts appear due to electromagnetic processes and the existence of flexible deformable units which disturb the manufacturing process. A method of limiting the increase in the voltage feeding the asynchronous electric drive with a multifunctional microprocessor regulator is proposed for correcting the speed regimes.
