RPM to Voltage Converter

Convert engine RPM (Revolutions Per Minute) to electrical voltage based on motor characteristics. This calculator can be used for understanding how engine speed affects electrical output in DC motor systems.

Input Parameters

Calculation Results

Calculation Formula

Voltage (V) = No-Load Voltage + (RPM × (No-Load Voltage - Voltage Drop at Full Load) / Maximum RPM)

Where:
V = Voltage at current RPM
No-Load Voltage = Voltage at zero load
Voltage Drop at Full Load = Voltage drop at maximum load
RPM = Current engine speed

Calculated Voltage (Volts)

RPM to Voltage Converter Calculator Usage Guide

Learn how to use the RPM to Voltage Converter calculator and its working principles

How to Use This Calculator

  1. Enter the engine RPM (Revolutions Per Minute) in the first input field.
  2. Enter the no-load voltage (volts) of your motor when it's running at zero load.
  3. Enter the voltage drop at full load (volts) - this is the difference between the no-load voltage and the full-load voltage.
  4. Click the "Calculate" button to compute the voltage at the current RPM.
  5. The calculated voltage will be displayed in the result field.

Working Principle

This calculator uses a linear relationship between RPM and voltage in DC motor systems. The formula assumes that the relationship between RPM and voltage is linear between no-load and full-load conditions:

Voltage (V) = No-Load Voltage + (RPM × (No-Load Voltage - Voltage Drop at Full Load) / Maximum RPM)

The calculator assumes a maximum RPM of 6000 for the calculation. This value can be adjusted if needed, but it's important to know the actual maximum RPM of your motor for accurate results.

Applications

This calculator is useful for:

  • Understanding how engine speed affects electrical output in DC motor systems.
  • Designing and tuning motor control systems.
  • Diagnosing electrical system issues in vehicles with DC motors.
