Guidelines For Calculation Of Pulleys And Rpm - Nogueira PN-MASTER 3000 Manual De Instrucciones

Guidelines for calculation of pulleys and RPM

See on this manual the speed ratio to operate the PN-Master 3000. To have different speeds in this
zone. Its necessary change the pulleys combination, that is, use differents diameters.
The formulas below will help you to discover which diameter is better to each pulley, according the
desired speed.

Diameter of
motor's pulley

Example of formula application
Machine pulley diameter = 195 mm
Motor pulley diameter = ? (this measure will be calculated)
Speed desired to the machine = 2.500 rpm
Motor's speed = 2.000 rpm (this value is an example, because it depends on the power)
2nd Formula: ?* 195 mm x 2.500 rpm
* In this example, the pulley assembled on the motor shaft should be a diameter or 244 mm.
