ELECTRIC DRIVE WITH ASYNCHRONOUS MOTOR WITH PREDICTIVE TORQUE CONTROL SYSTEM Russian patent published in 2024 - IPC H02P21/30 H02P21/12 H02P23/00 H02P27/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to an electric drive with asynchronous motors. Electric drive with an asynchronous motor with a predictive torque control system comprises a constant voltage sensor, a voltage inverter, phase current transducers, asynchronous motor, motor speed setter, adders, rotational velocity controller, motor stator flux linkage setter, cost function calculation unit, switching functions generation unit, electric drive state monitoring unit. Device also has a housing, at the bottom of which fastening elements are fixed, and inside which there is an additional unit for selecting a group of voltage vectors. Voltage vector group selection unit contains in-series installed relay motor stator flux linkage, the output of which is connected to the stator flux linkage relay state identifier input, which outputs and the output of the stator flux linkage vector phase sector determiner are connected to the matrix controller inputs, the output of which is connected to the input of the signal converter of the matrix controller, the output of which is connected to the input of the unit for calculating the cost function. Adder output is connected to motor stator flux linkage relay input.

EFFECT: increased energy efficiency of electric drive.
