Formation of asynchronous motor transient moments by the rate of change of the supply voltage.

Abstract

As a result of the study of the expression for the electromagnetic torque of the motor, it was found that in a certain range of the rate of change of the supply voltage, it is possible to limit the impact moments while simultaneously maintaining the drive speed. The rational limits of the speed variation of the power supply voltage were determined. The features of such modes when powering the engine through a thyristor switch and the possibility of their practical implementation are considered. The theoretical conclusions are confirmed by the simulation results. Figures 2. Bibliographic references 3.
