Re: troque

While your number is correct (300 or so ounce inches), that's the stall torque, at which point the motor is drawing 110-120A. Your breakers will pop well before then.

That does however give you the Torque Constant of the motor. For a DC motor like the CIM, we can assume that torque output is linear to current, so just divide the stall torque by stall current and you'll get the torque per amp.

Typically, we've designed for 1 N*m of torque from each CIM.
