Linear output, closed loop mover assembly

A mover assembly that adjusts a position or shape of an object along a first axis, the mover assembly comprising:

• a motor including a motor output that moves;
• and
• a coupling assembly including a stage that couples the motor output to the object and a stage guide that guides the motion of the stage along the first axis, wherein the motor output is moved along the first axis and about the first axis and wherein the stage guide is a linear bearing that allows for motion of the stage along the first axis and inhibits motion of the stage about the first, about a second and third axes, along the second axis and along the third axis.

A mover assembly that adjusts a position or shape of an object along a first axis, the mover assembly comprising:

• a motor including a motor output that moves and a pair of opposed jaw elements that engage the motor output, wherein the motor includes a piezoelectric element that causes rotation of the motor output by moving the jaw elements relative to each other;
• and
• a coupling assembly including a stage that couples the motor output to the object and a stage guide that guides the motion of the stage along the first axis and inhibits motion of the stage about a second axis that is orthogonal to the first axis.

• a motor including a motor output that moves, wherein the motor output is moved along the first axis and about the first axis;
• and
• a coupling assembly including a stage that moves with the motor output, a stage guide that guides the motion of the stage along the first axis and inhibits motion of the stage about the first axis, and a measurement system that provides information regarding the movement of the stage, wherein the stage guide is a linear bearing that allows for motion of the stage along the first axis and inhibits motion of the stage about the first, about a second and third axes, along the second axis and along the third axis.

A mover assembly that adjusts a position or shape of an object along a first axis, the mover assembly comprising:

• a motor including a motor output that moves along the first axis, wherein the motor output moves in a step-like fashion;
• and
• a coupling assembly including a stage that moves with the motor output, a stage guide that guides the motion of the stage along the first axis and inhibits motion of the stage about the first axis, a resilient member that urges the stage against the motor output, and a measurement system that provides information regarding the movement of the stage.
