How the Gear Ratio & RPM Calculator Works

The calculator uses three primary inputs:

1. Motor RPM – The rotational speed of the motor driving the system.
2. Driving Gear Teeth – The number of teeth on the motor’s gear.
3. Driven Gear Teeth – The number of teeth on the gear being driven.

The calculation follows standard mechanical engineering formulas:

• Gear Ratio = Driven Gear Teeth ÷ Driving Gear Teeth
• Output RPM = Motor RPM ÷ Gear Ratio

These calculations determine how the rotational speed of the motor translates to the driven gear, which is crucial in mechanical system design.

Step-by-Step Instructions to Use the Calculator

1. Access the Calculator: Open the tool on your device.
2. Enter Motor RPM: Input the motor’s speed in revolutions per minute.
3. Enter Driving Gear Teeth: Input the number of teeth on the motor gear.
4. Enter Driven Gear Teeth: Input the number of teeth on the driven gear.
5. Click Calculate: Press the “Calculate” button to start the computation. A progress bar will indicate the process.
6. View Results: The calculator will display the gear ratio and output RPM.
7. Copy or Share Results: Use the “Copy Results” button to save the output or “Share Results” to send it to team members.
8. Reset Inputs: Click the “Reset” button to clear all fields and perform a new calculation.

Practical Example

Imagine a motor operates at 3000 RPM, with a driving gear of 20 teeth and a driven gear of 60 teeth. Using the formulas:

• Gear Ratio = Driven ÷ Driving = 60 ÷ 20 = 3
• Output RPM = Motor RPM ÷ Gear Ratio = 3000 ÷ 3 = 1000 RPM

This means the driven gear will rotate at 1000 RPM, three times slower than the motor, which is essential for designing the correct speed reduction in machinery.
