Algorithmic methods of providing electromechanical compatibility in asynchronous drive with variable-frequency power supply

A computer model was developed for to research purpose of electromechanical compatibility in asynchronous drive. On the basis of Based on this computer model, the influence of PWM-VSI’s inverter frequency and load value of asynchronous motor shaft load on the level of electromagnetic torque pulsing was investigated. Results of modeling are presented and recommendations for converter’s control algorithms modification, and improving electromechanical compatibility of asynchronous drive, are formulated.
