Способ управлени бесконтактным электродвигателем посто нного тока

摘要

FIELD: electrical engineering; reversible variable-speed drives. ^ SUBSTANCE: proposed method includes generation of differential output signal equal to total signal proportional to motor shaft speed increment within modulation period and signal proportional to alternating component of motor electromagnetic torque, as well as generation of sweep signal equal in amplitude and opposite in polarity to alternating component value of motor electromagnetic torque predicted after change-over of switching components. ^ EFFECT: enlarged functional capabilities. ^ 1 cl, 1 dwg
