Two Pulley Calculators from homemetalshopclub.org How do you calculate pulley size? The motor pulley is less costly, it is the easy one to change, and as the smaller of the two pulleys, it probably has the greatest wear on it. Say you want to know what size pulley to use on that old planer to get 3450 rpm, you know the motor rpm is 1725 and the pulley on the motor is 6. How to determine pulley size? To use this calculator you must enter at least 3 values in the spaces below. Take the stated motor rpm (or measured) and simply apply the appropriate ratio to the diameter of the motor pulley to get the speed you want. For example, given a drive speed of 750 rpm, the speed of the first pulley = 750/2 = 375 rpm, and the speed of the second pulley = 750/1.27 = 591 rpm. Multiplication factor = rpm out/rpm in = 1002.13/1773 =.5652
