FIELD: electricity.
SUBSTANCE: device comprises three-phase asynchronous motor, which parameters are to be estimated, sensors of stator phase voltage, sensors of stator phase current, phase voltage converter and stator phase current converter that allow conversion of stator phase voltage and current to voltage and current of generalised machine, estimated model of the asynchronous machine, five calculation units for parameters estimation, summators. The device allows estimation of parameters, variable values and frequency of asynchronous motor rotation rate without usage of speed transducers, rotary acceleration sensors and differentiators.
EFFECT: extension of application area.
