FIELD: mechanical engineering. ^ SUBSTANCE: device has signal form generator, power amplifier and electromechanical block, including first fixed magnetic system and first coil of current-conductive wire, additionally included are integrator and corrector of amplitude-frequency characteristic of electromechanical block, and block also has second fixed magnetic system and second coil of current-conducting wire, rigidly and coaxially connected to first coil. Connection of first and second coils with fixed base is made in form of soft suspension with possible movement of first and second coils, forming a moving part of modulator, relatively to fixed magnetic systems, while output of said signal shape generator is connected to direct input of integrator, inverse input of which is connected to speed sensor of moving portion of modulator, output of integrator is connected to input of corrector, to output of which input of said power amplifier is connected. ^ EFFECT: higher precision. ^ 3 cl, 8 dwg
