METHOD TO DEFINE ESTIMATE OF FREQUENCY OF INDUCTION MOTOR ROTATION Russian patent published in 2013 - IPC H02P23/14 H02P27/04 

FIELD: electricity.

SUBSTANCE: instantaneous values of currents and voltages in an induction motor stator are measured, simultaneously they measure instantaneous values of currents and voltages on two stator phases, they serially perform three time delays at least by 6 ms, producing current and once, twice and thrice delayed values of currents and voltages of two phases of the motor stator, with the help of a pre-trained artificial neuron network, on the basis of experimental data on operation of the electric motor in all modes, using dependences detected by the artificial neuron network in process of training between input and output data, they determine instantaneous value of estimated frequency of induction motor rotor rotation with the help of formulas given in the application materials.

EFFECT: spreading of range of facilities of similar purpose.
