Linear Stage - Position Control Methods

Position Control Methods

The position of the moving platform relative to the fixed base is typically controlled by a linear actuator of some form, whether manual, motorized, or hydraulic/pneumatic. The most common method is to incorporate a lead screw passing through a lead nut in the platform. The rotation of such a lead screw may be controlled either manually or by a motor.

Famous quotes containing the words position, control and/or methods:

    “Unfortunately, life may sometimes seem unfair to middle children, some of whom feel like an afterthought to a brilliant older sibling and unable to captivate the family’s attention like the darling baby. Yet the middle position offers great training for the real world of lowered expectations, negotiation, and compromise. Middle children who often must break the mold set by an older sibling may thereby learn to challenge family values and seek their own identity.”
    —Marianne E. Neifert (20th century)

    “Not being able to control events, I control myself; and I adapt myself to them, if they do not adapt themselves to me.”
    —Michel de Montaigne (1533–1592)

    “I believe in women; and in their right to their own best possibilities in every department of life. I believe that the methods of dress practiced among women are a marked hindrance to the realization of these possibilities, and should be scorned or persuaded out of society.”
    —Elizabeth Stuart Phelps (1844–1911)
