Re: Servo torque test question

Bob,

You can do that, or you can read motor torque directly by inserting
an ammeter in series with one of the motor leads. Let's say your
motor develops 400 oz-in at 20A. This means a 20 oz-in load will draw
1A of current, 100 oz-in will draw 5A, etc. For best accuracy,
subtract the motor's no-load current from the indicated reading.
