Calculation of Torque for Drive Pulley of Roller Conveyor. May 06, 2017· 5.5 HP = 4125W 1500rpm = 157 Radians/second So the torque at the motor is 4125/157 = 26Nm The gearbox reduces rpm and multiplies the torque so torque at the output of the gearbox/drive pulley should be something like.. 26 * 1500/95 = 410Nm But that could be greatly exceeded.
