    velocity-dependent motor sounds, and. • prevent additional heat generation,. • so allowing the motor to realize its maximum mechanical power rating. The effi ciency of a linear motor is therefore greatly infl uenced by the selection of the position encoder. Encoders with optical scanning. methods provide benefi ts

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

    by factoring in motor behavior when managing velocity feedback. Velocity algorithms and linear quadratic regulators, In a servosystem, velocity disturbances are a manifestation of how the system reacts to outside effects caused by various components. If all system components are perfect
  • Important Considerations When Selecting Digital Encoder Outputs (.pdf)
    . rotary encoders are used. Within linear or rotary encoders there are two basic types of electrical output formats;. incremental or absolute. Absolute encoders have a unique digitally coded output or. address for every distinct position of the encoder. Incremental encoders will output a. count
