MODE OF RECEIVING A FEEDBACK SIGNAL IN STRUCTURES OF CONTROL SYSTEMS OF ELECTRIC DRIVES WITH SUPPORTING FLUX-LINKAGE OF AN ELECTRIC ENGINE

摘要

FIELD: the invention refers to the field of electric technique and may be used in control systems of electric drives of direct and alternating current. ^ SUBSTANCE: in the mode of receiving a feedback signal in the control structures of electric drives with supporting flux-linkage of an electric drive in quality of a feedback signal they use value of the flux-linkage arising in the cut of the magnet conducting plate installed on the stand of the electric engine between the polar divisions. The feedback signal acts also at zero assignment because the given signal directly depends from flux-linkage in the gap. Therefore having once tuned the control system of the electric drive at nominal regime of work, the received feedback signal allows further controlling deviations of the flux-linkage from nominal value and that is the main assignment of the control systems of electric drives with supporting the flux-linkage. ^ EFFECT: provides simplicity of receiving a feedback signal and support of required trans-shifting capability of the electric engine at zero assignment. ^ 2 dwg
