RPM Calculator Between Two Pulleys
Use this calculator to find the RPM of any machine between two pulleys with motor RPM. Drive & Driven pulleys size will be in mm or inches. However, this tool is useful when you need to change the speed of the machine, or adjust the RPM by changing the pulley size.

How RPM is Calculated
You can calculate the RPM of the driven pulley using the following formula:
Driven Pulley RPM = (Motor RPM × Drive Pulley Diameter) ÷ Driven Pulley Diameter
By adjusting the size of the pulleys, you can increase or decrease the speed of the driven pulley based on the motor's RPM. However, for more industrial calculations, you can visit our home page.
FAQs
RPM stands for Revolutions Per Minute, which measures how many complete turns an object
makes in one
minute.
The larger the drive pulley relative to the driven pulley, the higher the driven pulley's
RPM. Conversely,
a larger driven pulley will reduce RPM.
You can use this calculator to calculate a variety of pulleys, provided the diameter and
motor RPM are input correctly.
To increase the RPM of a machine, increase the pulley dia of a motor or decrease
the driven pulley diameter.
The drive pulley is connected to the motor, while the driven pulley
receives the power
and rotates in response at a different RPM.
Yes, RPM can be measured manually using a tachometer or by counting the number of rotations
within a set
time frame.
RPM ensures that the machine operates within a safe and efficient speed range.
This prevents wear and tear and improves performance.
The calculator is designed for mm, and inches, but you can adapt it for other
measurement
systems by adjusting the conversion factors accordingly.
Yes, this calculator can be used for any pulley system, as long as you input the correct
measurements for
the pulleys.
