Motor

The principle of a "Pulay and Belt" system used to convey power from the motor (power early Pulay) to the power receiving Pulay, whereby the rotation rate of the power receiving Pulay can be calculated using the formula as follows:

Elements in the image:

1.A = Power Tree Poolay (Puley Motrice)

A pulay attached to a motor and so on, which has a defined cycle speed (RPM) and diameter (& # 174;).

2.B = Puley Conducida

The pulay driven by the belt, which we want to find the RPM speed.

The formula used to calculate:

\ text {RPM} _ B =\ frac {\ Phi _ A\ times\ text {RPM} _ A} {\ Phi _ B}

Where:

= Diameter of power tree pulay (A)

= Diameter of power receiving pool (B)

= Cycle speed of the power pool

= The required speed of locating the power receiver Pulay

Example in the picture:

Power tree pool diameter () = 6 cm

Pulay diameter, taking power () = 15 cm.

Cycle Speed of Power Tree Pulay () = 1700 RPM

Calculate for:

\ text {RPM} _ B =\ frac {6\ times 1700} {15}

\ text {RPM} _ B =\ frac {10200} {15}

\ text {RPM} _ B = 680\,\ text {RPM}

Results:

The cycle speed of the power receiving pool (B) is 680 RPM.

This reduction in cycle speed size is due to the use of a larger diameter pulay, resulting in a decrease in the rotation cycle of Pulay B compared to Pulay A.
