FIELD: electrical engineering.
SUBSTANCE: method for optimizing the operation of an asynchronous machine in terms of the minimum stator current and maximum efficiency with field-oriented vector control consists in alternately setting different ratios of the flux-generating and torque-generating stator currents Id, Iq, forming the same torque on the shaft, and calculating the current value at each step and efficiency in order to check the achievement of an extremum in terms of the minimum current and maximum efficiency by monitoring the monotonicity of the decrease in the function I(Id) and the increase in the functionη (Id).
EFFECT: increasing the efficiency of the electric machine.
