I have found the following in the FAQ:
The Vex Motor Stall Torque is approximately 6.5 inch*lbs.
All the other servos list the stall torque in oz/in. What would be the stall torque for VEX servos in oz/in?
Also what is the stall amperage?
Torque is measured in units of FORCE*DISTANCE, so oz/in is an incorrect term.
I googled “servo specs” and all the ones I came across are in oz-in which is the same as oz*in.
(ex: http://www.futaba-rc.com/servos/servos.html)
Using [www.onlineconversion.com (one of my favorite websites), I show that 6.5 lbinch is the same as 104 ozin.
The original spec posted for the Vex servo was experimentally calculated. It is difficult to get a good measurement on this, because when the motor is stalled, it’s thermal protection kicks in and kills the motor. So your mileage may vary. If you experimentally determine a different number, we’d be happy if you share it on this forum.
I ask Ricky to post the motor stall current, asap.
