07/06/2019 For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a) on the belt multiplied by the radius (r 1) of the drive pulley. T c = torque required during constant velocity (Nm) F a = total axial force (N) r 1 = radius of drive pulley (mm)
