  • Sizing and Applying Magnetostrictive Linear Position Sensors
    of the time. delay indicates the location of the position magnet. For example,. at a measured distance of 1 meter with a waveguide velocity of. 2850 m/s, the time delay would be: Figure 2: Basic components of a Magnetostrictive Linear-Position Sensor. 1 meter ÷ 2850 meters/second = 0.35 milliseconds
  • Encoder vs. Resolver-Based Servo Systems (.pdf)
    all parts of the machine in step at a given pace. Electronic motion controllers use devices called transducers to accurately resolve and encode the position of a motor. shaft, other rotating shaft, or linear movement on a machine. Through the history of machine development the com-. mon names adopted
  • Measurement Techniques for Incremental Sensors: Encoders, Frequency Counters, Magnetic RPM sensors, etc.
    timing measurement) relates. a uniformly indexed ruler performing the same function as the. rate of change. uniformly divided disc in a rotational measurement. Since the. For example, an incremental encoder is a common device used. same principle applies to both rotational and linear encoders
  • Positioning Components
    . A controller then uses a translation table in memory to relate the code read from the transducer into system position. Absolute encoders are available in both rotary and linear optical types. Tachometers are probably the most widely used velocity transducer. In addition, velocity transducers
  • Advanced photonics will ride on air
    is the NanoDrive linear amplifier, which is often paired with 4096X-encoder interpolation for use in photonics applications. All moving objects possess six degrees of freedom -- three linear and three rotary. The task of a linear-motion guideway is to eliminate, as closely as possible, five
  • Setting the stage for good machine design
    friction can make it difficult to maintain a constant velocity. Under some conditions, such as temperature or humidity extremes, the pitch of the ball screw can change and affect accuracy. If thermal effects are an issue, a linear encoder may be required or a linear-motor stage may be a better choice

  • Precision moves with pint-sized motors
    in this configuration. It says this rate can produce linear velocities of about 130 mm/sec. Users can gang EDO motors together to boost applied force if need be. It is also possible to convert this linear motion to circular motion by letting the EDO device push the outside radius of a disc. The piezomotor has
