FIELD: mechanical engineering. SUBSTANCE: device has rotary drive with pull-back spring and connecting rod connected with rotary drive to transmit linear motion to mechanical member. Rotary drive has rotating electromagnet whose angular position is regulated by pulse and periodic current. Special device is provided to remove magnetization energy accumulated in electromagnet. EFFECT: simplified automatic control system owing to the less pronounced phenomena of resonance and instability. 10 cl, 10 dwg
