Electric motor pulley rpm formula.
And the formula for calculating torque will be.
The rpm of the first driven large pulley is transferred to second set small driver pulley and so on.
Why do you need to connect the motor to the load.
Assume a power shaft pulley size of 4 inches.
The sets of pulleys will be drawn at the bottom of the page with each set rpm reductions and total rpm reduction through all entered sets.
N revolution per minute rpm alternatively.
Multiply by the speed ratio.
This is generally a good size for efficient belt operation.
If you have any problems with the pulley calculator please email us.
Check the circle next to the item you are solving for and enter the remain three items in the spaces provided.
The result will give the load shaft pulley size.
In the example below the pump rpm is 1070 for full output while the motor is 1750 rpm.

125 cm 17 76 seeds 7 04 cm.
Get the speed ratio by dividing the speed in rpm of the power shaft by the speed in rpm of the load shaft.

Below is a small calculator that will solve the ratio for you.
There are complicated formulas for determining pulley ratios but in generic layman terms simply divide the driven component pump by rpm the driver component motor or engine rated by rpm to get the required ratio.
The cell plate 45 cell x 0 395 rpm 17 76 seeds drop in one revolution.
Calculate the sizes of the pulleys.
The math of pulley sizing.
Well if there is no load there is no torque.
Motor and equipment speed for pulleys with different diameters are indicated in the charts below.
Using the motor from generator kit is the best way to do it.
τ rpm 2π 60 i v e.
In this instance the initial small driver pulley rpm is 2000.
T inlb torque in lb f.
Torque in imperial units can be calculated as.
