  • Optical Shaft Encoders
    encoders are preferred when low cost is important, or when only relative position is needed. Their output typically consists of two square waves, each corresponding to an increment of rotation. Incremental encoders often have a third channel with a single segment slot or reference which is used to zero
  • When to go Linear
    . Optical encoders use a light scanning principle where two scaled gratings of equal graduations move relative to each other. A reflective glass or steel-tape media has nonreflective stripes forming one grating. An index grating of opaque strips on a transparent material moves along the reflective media
  • Eliminating sensors from closed-loopcontrol
    relative to the stator field. The controller uses this data to regulate voltage, current, and frequency through a pulse-width modulator to the motor. Torque, therefore, is controlled indirectly. This system provides good torque response, accurate speed control, and can produce full torque at zero speed
  • Motor Follower - Electronic Gearing
    Encoder tracking is a technique that monitors a reference motor with an encoder and controls a secondary motor. The method provides programmable motor-to-encoder ratios that determine relative speed between two axes. A dynamic change in ratio produces acceleration or deceleration. Absolute
  • Guide Sensor : Step Analog type
    GS-2744B is step analog voltage output type magnetic navigation. sensor for AGV. GS-2744B is composed of 15 bit MACOME original. magnetic sensor elements "saturable coil", encoder and D/A. converter. The step analog voltage (DEVIATION OUT) changes. proportional to relative position between GS-2744B
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems
    connections to the upper axes are static which means there is no bending or relative movement of the cables. By shortening the cable length, the main concerns of crosstalk and radiation are eliminated. Instead of a bulky central motion controller, only an external. power supply is needed which is usually
  • No contact means no headaches in position transducing
    , producing greater accuracy. Because the noncontacting potentiometer's 2 by 6-mm pickup probe covers a larger area than contacting wiper points, the relative gradient, or slope variation, of the probe's output is relatively flatter. Less variation means reduced noise, and a more accurate signal
  • Finding the right sensor for linear displacement
    . They are not threshold-type devices, like proximity sensors, which only determine if an object is present and whether it has moved to or passed a specified location. These sensors are also classified as either absolute or incremental (relative) sensors. Absolute sensors generate the same output after a power
