That would make sense, using P=V*I, but for whatever reason FIRST defines servos likes this.
Quote:
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)
|
Following this steps from
this post and
this and from the spec sheet above.
Quote:
Free Speed 100 RPM @ 7.5 Volts
Stall Torque 6.5 in*lbs (approximately)
|
So Torque = 6.5inlbs=0.7344Nm (According to online converter)
100*.7344*0.1046=7.68Watts
So if all my math is right and I am converting everything proper, it does not seem that servo is under 4watts.
