    please include equations and the works
    A 12V DC motor has a stall torque of 2 mNm, a stall current of 5 A, and a no load speed of 8000 rpm. What is the torque constant?

    Read the current draw at a given torque on the Typical Performance Characteristics graph. Now divide the torque by the current.
