SERVO DRIVE Russian patent published in 1997 - IPC

FIELD: automatic control systems, mechanical engineering, machine tool manufacture. SUBSTANCE: invention can be used for movement of objects within wide range with high precision and fast response. Servo drive has position meter 1, comparator 2 to compute error signal between specified position of object and readings of meter, former 3 of controlling action, motor 4, guide 5 kinematically coupled to motor, base rests 6 and pressure rests 7, nonlinear unit 8 to set minimal moving force which value is bigger than difference of moduli of forces of dry friction in base and pressure rests of guide and less that their sum is, unit 9 used to ensure periodic motion of base and pressure rests along; travel of guide in opposite directions in accordance with error signal of comparator. EFFECT: widened range of application of servo drive, high precision eng fast response. 1 dwg
