OSCILLATING MOVEMENT ELECTRIC DRIVE Russian patent published in 2000 - IPC

FIELD: electrical engineering, in particular, electric drives, which actuating body performs oscillating and reciprocal movements, for example, for mechanical testing of cables for multiple bends, arranging long articles, while their are turned over coils, reels, and so on. SUBSTANCE: Goal of invention is achieved by introduced position detector which is mounted on rotor of electric motor. Reverse pulse counter, amplitude setter, central processing unit and pulse generator are introduced into frequency converter. EFFECT: increased functional capabilities and increased precision of operations due to stabilization of oscillation amplitude because of feedback circuit for rotor position and regulation of oscillation frequency of shaft of actuating motor. 2 dwg
