Calculating Load Capacity for a Linear Servo: Is My Math Correct?

Click For Summary
SUMMARY

The discussion centers on calculating the load capacity for a linear servo slider with a maximum allowable dynamic moment of 36.3 Nm. The user calculated the load capacity based on an acceleration of 0.3G, an offset distance of 305mm, and a load mass of 50lb. The calculation yielded a maximum load capacity of approximately 88lbs (40Kg), confirming that the slider can move the specified mass. The math presented is accurate based on the provided parameters.

PREREQUISITES
  • Understanding of dynamic moments in mechanical systems
  • Familiarity with linear motion and servo mechanisms
  • Basic knowledge of unit conversions (e.g., pounds to kilograms)
  • Proficiency in applying Newton's second law of motion
NEXT STEPS
  • Research "Dynamic Moment Calculations in Mechanical Systems"

I have a linear slider with the following specs:

Max allowable dynamic moment: 36.3 Nm
Load capacity based on acceleration of: 0.3G
Offset distance from center of slider to center of load: 305mm
Mass of load: 50lb

I did the following calcuation

36.2N*m = X(Kg) * 305mm * 0.3G * 9.8/1000
X = 40Kg or approx 88lbs

I can conclude this slide is capable of moving this mass.

Is my math correct? :)

Thanks!
