CALCULATORS / MECHANISMS

Lead screws and linear stages

Screw kinematics with efficiency and load assumptions.

lead, RPM, load, efficiency → thrust, travel speed, drive torque

lead, load, speed, efficiency, stroke → torque, power, nominal selection constraints

lead angle, friction, thread geometry → backdrive screening, required brake torque

unsupported length, diameter, end supports → critical-speed estimate, usable speed range

root diameter, unsupported length, end conditions → Euler buckling estimate

lead, encoder counts or steps, gearing → nominal increment, quantization

screw, nut and drivetrain lost motion → linear deadband, direction-change error

moving mass, friction, acceleration, stroke, duty → required force, speed, peak and RMS power
