Abstract:
The present invention relates to a torque detection device comprising a torque detection part for outputting an analog torque signal and a digital torque signal by detecting the torque of a rotor; and a torque signal processing module for estimating an estimated digital torque signal from the analog torque signal and an estimated analog torque signal from the digital torque signal based on a preregistered estimation algorithm, and determining a final torque signal based on a first deviation between the analog torque signal and the estimated analog torque signal and a second deviation between the digital torque signal and the estimated digital torque signal Accordingly, the present invention can precisely control the torque strong to external noise by supplementing the weakness of the analog and digital torque signals using the analog and the digital torque signals together.
Abstract:
PURPOSE: A servo motor system for accurately controlling torque is provided to control overshoot no more than a target torque by inhibiting a movement of a motor over the target torque with a torque controlling position compensator. CONSTITUTION: A torque detector(191) detects torque of a servo motor by receiving a first electrical signal from a load cell. The first electrical signal corresponds to a load according to a movement of a servo motor. A sequence controller(110) generates a target position order. A torque control position compensator(131) receives a second electrical signal from an encorder. The torque control position compensator detects a position of a servo motor. The torque control position compensator generates a feedback position signal. The second electrical signal corresponds to a revolving position of a servo motor.

Abstract:
PURPOSE: An automatic press device for separating a margin to seam is provided to improve work efficiency by automatically ironing the margin to seam. CONSTITUTION: A sewn good support unit(110) supports sewn goods. The sewn good support unit supports a margin to seam. A first press unit(120) performs primary ironing to the margin to seam. A second press unit(130) pressurizes the ironed margin to seam. A second press unit performs secondary ironing to the margin. A pedal manipulating unit(140) executes or stops the first and the second press units.
Abstract:
PURPOSE: An active walking aid and a driving method thereof are provided to assist the walking of user by determining accurate walking direction. CONSTITUTION: An active walking aid comprises a support(110) supporting the elbow of the user, a first and a second handle bar(120) which are installed on right and left sides of the support and equipped with at least one sensor for sensing the force applied by the user, and a controller(140) which determines walking direction by applying the sensed force and the variation thereof to fuzzy algorithm and outputs a driving signal for driving a motor of wheels according to the results.
Abstract:
PURPOSE: A wafer flat zone aligner including an edge crack detecting function and a driving method of the same are provided to simultaneously perform a flat zone align operation and an edge crack detecting operation by splitting one laser using a beam splitter. CONSTITUTION: A beam splitter(4) splits laser from laser source into two lasers. A first optical system(2) horizontally radiates first laser split from the beam splitter to the surface of a wafer along a first path. A second optical system(3) radiates second laser split from the beam splitter to the surface of the wafer along a second path. A first optical sensor(9) detects a first laser transmitted through the float zone of the wafer. A second optical sensor(14) detects the second laser transmitted through the edge crack of the wafer.
