Claim 2:
3. The torque estimation system according to claim 1, further comprising:
torque estimation means for estimating the friction torque of the rotation mechanism using an estimation model of a friction model generated by machine learning, wherein
the torque estimation means outputs the friction torque when the torque estimation means determines that the estimated friction torque is not equal to or greater than the upper limit value or is equal to or less than the lower limit value set by the limit value setting means, and
the torque estimation means does not output the friction torque when the torque estimation means determines that the estimated friction torque is equal to or greater than the upper limit value or is equal to or less than the lower limit value set by the limit value setting means.
