Instrument Positioner Actuator Calculator

How the precision instrument vertical stage works

A guided carriage carries side loads and bending moments. Axial effort includes gravity along the guide, guide friction, measured resistance and the entered acceleration. Synchronization and guide design are separate from actuator thrust.

Measurements for this application

Measure stage travel, moving optics or instrument mass and guide drag. Positioning resolution depends on the controller and sensor.

• Record required movement, guide angle above horizontal, load offset from guide center, maximum retracted pin space, maximum working pin space. Measure between pivot or mounting-pin centers.
• Account for instrument weight, moving structure weight, guide friction coefficient, measured breakaway / process force. Use the heaviest permitted operating condition.
• Enter the actual motion limits and check the mechanism at both ends and through the full path.

Choosing an actuator for precision instrument vertical stage

The calculator checks the required force, stroke and mounting length before displaying variants. Super Duty actuators take priority, followed by Utility and C-Series where their dimensions and ratings fit. Industrial actuators take priority above 450 lbf of moving load or required actuator force; feedback Micro Pen actuators take priority for the humanoid finger.

Compare exact variants, set travel limits for any unused stroke, and verify the controller, duty cycle, environment and mounting details. Save the design or download its engineering brief to keep your measurements and results together.

What does this calculator solve?

Precision instrument vertical stage is solved along the entered start-to-end path. The animation follows those measurements and the force plot shows the demand through the move. The stated model assumptions define which parts of the real mechanism are included.
