The approximate motor torque required to produce a given force can be determined using the above chart:

Find the peak force on the horizontal scale and draw a vertical line from this value through the data line. From the intersection point, draw a horizontal line to the vertical legend on the left. This torque input will produce the peak axial force defined above for an in-line or parallel offset 1:1 gear belt ratio. For a 2:1 gear belt ratio, the required torque is reduced by 50%.
