0. Yes, motor torque depends on load. More the load torque more the torque produced by motor. Yes, as previously mentioned answers every motor have some losses, that may be friction losses etc, and at no load the motor will produce a torque equal to the torque due to loss. So the some of Torque produced = Load torque + Torque (friction loss).

The torque is obtained by integrating the frictional force multiplied by roll radius over the arc of contact (lagging and leading zones). The negative sign before the second term is due to the fact that in leading zone the metal moves faster than the rolls hence it helps to rotate the rolls.
