Annotation: The paper provides the results of the analysis of electromagnetic hysteresis couplings designed for operation in the pipeline valves electric drives for oil and gas automated complexes. It is shown that the Fe-Cr-Co hysteresis coupling can be an alternative to technical solution of the intelligent electric drives based on the asynchronous electric motors. The results of the electromagnetic analysis of four types of hysteresis couplings to be used in the electric drives of the stop valves up to 7.5 kW are obtained.
