METHOD TO CONTROL ELECTROMAGNETIC TORQUE AND MAGNETIC FLOW OF AC ELECTRIC MACHINE

摘要

FIELD: electricity.SUBSTANCE: in the method of control of electromagnet torque and magnetic flow of an electric machine of AC current at first the specified value of electromagnetic torque is established, as well as the specified value of stator flux linkage amplitude, the specified value of the limit stator current, and instantaneous values of current and flux linkages of the stator are determined, as well as the value of the electromagnet torque. Then phase voltages of the stator are calculated and formed.EFFECT: reduction of dynamic loads in a transmission device of an electric drive, limitation of currents consumed by an electric motor, increased reliability of a system of electric drive control.8 dwg
