Servo watts calculation

The best way to get to Einstein is to analyze the game, figure out which three robots would make up the ideal Einstein alliance, and then design, build, iterate, and polish the one that best matches your teams' capabilities. - Jared Russell [more]

Servo watts calculation

According to R18:

Quote:

PWM COTS servos with a maximum power rating of 4W each at 6VDC
Per the Servo Industry, Servo Max Power Rating = (Stall Torque) X (No Load Speed)

I'm wanting to do the calculation for the HS-422 servo. Can someone verify my work?

Assumes 6v power at PWM port on roboRIO.

Torque T = 4.1 kg-cm = .4 N-m
Angular speed w = .16sec @ 60 degrees

Watts W = N-M / s = .4 / .16 = 2.5
