How the Gear Ratio RPM Calculator Works

The calculator requires three key inputs:

1. Motor RPM: The speed of the motor in revolutions per minute.
2. Input Gear Teeth: The number of teeth on the driving gear connected to the motor.
3. Output Gear Teeth: The number of teeth on the driven gear receiving the motion.

The tool uses the standard gear ratio formula:

Gear Ratio = Output Gear Teeth ÷ Input Gear Teeth
Output RPM = Motor RPM ÷ Gear Ratio

This calculation allows you to determine how fast the output gear will rotate based on the motor speed and gear configuration.

Step-by-Step Instructions to Use the Calculator

Follow these steps for accurate results:

1. Open the Calculator: Access the Gear Ratio RPM Calculator on your device.
2. Enter Motor RPM: Input the revolutions per minute of your motor.
3. Enter Input Gear Teeth: Provide the number of teeth on the input (driving) gear.
4. Enter Output Gear Teeth: Specify the number of teeth on the output (driven) gear.
5. Click Calculate: Press the “Calculate” button. The progress bar will indicate the calculation process.
6. View Results: Once complete, results will display the gear ratio and output RPM.
7. Copy or Share: Use the “Copy Results” or “Share Results” buttons to save or send results.
8. Reset (Optional): Click “Reset” to clear fields for a new calculation.

Practical Example

Suppose you have a motor spinning at 3000 RPM with a gear setup where the input gear has 20 teeth and the output gear has 60 teeth.

Step 1: Calculate Gear Ratio
Gear Ratio = 60 ÷ 20 = 3.00

Step 2: Calculate Output RPM
Output RPM = 3000 ÷ 3 = 1000 RPM

This means the output gear rotates at 1000 RPM, providing a clear understanding of how gear size affects speed and torque.
