Annotation: The calculation procedure of item output of the valve electric drive in oscillatory mode subject to electric machine parameters, load and adjustment functions has been developed. The adjustability of the valve electric drive natural frequency through drive operating element’s position feedback has been specified. The comparative evaluation of electric drive operating efficiency with position feedback has been conducted. The functional diagram that implements natural frequency control mode of electro-mechanical system has been given.

Keywords: valve electric drive, natural frequency, oscillatory motion, resonant mode, reversed feedback
