COMPENSATING DEVICE OF MOTORS FOR THE TORQUE DUE TO GRAVITY

摘要

PURPOSE: A compensating device of motors for the torque due to gravity is provided to easily be applied to a small motor and a large motor by compensating gravity through a simple structure. CONSTITUTION: A rotary shaft(120) is pivotally formed at the supporting frame. A load(130) is fixed to the rotary shaft in order to be rotated with the rotary shaft. A drive motor(140) applies rotation power to the rotation shaft. One end of a torsion bar(150) is connected to the rotary shaft. The torsion bar forms a rotation unit with a rotary shaft. The other end of the torsion bar is combined with a support frame to form a fixing unit with the rotary shaft.
