    Hello everybody. Can anybody help me figuring out the torque of a brushless motor. for example this motor: http://www.robotmarketplace.com/products/0-GPMG5155.html

    it says it has a kv rating of 3180rpm/V so if I run it at say 11v it equals 34,980 rpm no load speed right? know how do I know the stall torque of the motor with the specs given in the site. It doesn't mention anything about torque and I also checked the documentation of the motor and it also doesn't say anything. basically how can I find out the torque constant?

    This motor is just an example I would want to be able to calculate the torque for different motors not just this one.

    Every half-decent motor manufacturer rates the torque of its motors. Not this one.
    Cheap motors from GWS in Taiwan rate the torque of all its motors.
