Tc = torque required during constant velocity (Nm) Fa = total axial force (N) r1 = radius of drive pulley (mm) η = efficiency of belt drive system. Notice that the efficiency (η) of the belt drive system is included in the torque equation. This efficiency accounts for losses such as friction between the belt and pulleys.Web
