How to Use the Calculator

Input Motor RPM

  1. Enter the rotational speed of the motor in Revolutions Per Minute (RPM).
  2. This is the input speed to the gearbox.

Input Gear Ratio

  1. Enter the gear ratio of the gearbox.
  2. A ratio of 10 means the output speed will be 1/10th of the input speed.
  3. Ensure the ratio is greater than 0.

Calculate Output RPM

  1. Click the "Calculate" button.
  2. The result will show the output rotational speed of the gearbox in RPM.

Motor Gearbox RPM Fundamentals

Motor RPM

Motor RPM (Revolutions Per Minute) is the speed at which the motor's output shaft rotates. It's the primary input for a gearbox system.

Gear Ratio

  • The gear ratio defines the relationship between the input and output speeds of a gearbox.
  • It's calculated as the number of teeth on the output gear divided by the number of teeth on the input gear, or simply Input Speed / Output Speed.

Key Formula:

Output RPM = Motor RPM / Gear Ratio

Calculation Formulas

Output RPM:
Output RPM = Motor RPM / Gear Ratio

Example Calculation

Motor RPM: 1800 RPM

Gear Ratio: 10:1 (Enter 10)

Output RPM = 1800 RPM / 10 = 180 RPM

Result: 180.00 RPM
