Precise positioning stage of THK PRECISION

Is the only difference between a "piezo stage" and a "piezo motor stage" the amount of movement?

• Target Products

  Piezo Stage, Piezo Motor Stage

• Issues

  I would like to know the difference in features between "piezo stage" and "piezo motor stage," which are precision positioning stages with nanometer accuracy, and to make a selection decision.

• Response and Suggestions

  Piezo stage" and "piezo motor stage" both use a piezo element (piezoelectric element) as a drive source, but the difference is not only in the amount of movement, as the principle of operation is different.

  • piezo stage

    

    [Drive Principle]	Table is moved through expansion/contraction of piezoelectric element.
    [Main Features]	Limited stroke Ultra-high resolution Fast response

  • Piezo Motor Stage

    

    [Drive Principle]	Table is fed gradually through repeated extension and bending of four legs.
    [Main Features]	Long strokes possible High resolution Maintains the stop position even when the power is turned off
