Even without guard rails, if the package is too long and overhangs the curve, it may contact items outside the curve, causing a jam. Enter the dimensions (in inches) into the calculator to find the proper width for your curve to avoid jams. Please enter all dimensions in inches. BR is the distance "Between the Rails" of the curve.    ### Motor Sizing Calculations - Oriental Motor U.S.A. Corp.

Oriental Motor commonly provides inertia in oz-in². Then, when we calculate the Acceleration Torque in Torque Calculation we divide the total the total inertia by the gravity from. Gravity = 386 in/sec². oz-in² = Inertia based on weight. oz-in-sec² = inertia based on mass. Calculation for oz-in² to oz-in-sec².    ### Conveyor Calculators | Configuring Conveying Equipment

This calculator contains multiple calculators for various aspects of incline conveyors specification. We can always assist you when it come to conveyor specification. If you do not specify your curve to be wide enough, packages may become jammed against guardrails, or overhang the curve and contact nearby obstructions causing a jam or damage.    ### Calculation of Torque for Drive Pulley of Roller Conveyor

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.    ### CaLCULaTIOn METHODS – COnvEYOR bELTS - Microsoft
