Motor Absorbed Power Calculator Usage Guide

Learn how to use the Motor Absorbed Power Calculator and its working principles

How to Use

  1. Enter the voltage (in volts) of your motor
  2. Enter the current (in amperes) flowing through your motor
  3. Enter the power factor of your motor (typically between 0.7 and 0.9 for motors)
  4. Click the "Calculate" button to compute the absorbed power

Working Principle

The absorbed power (also known as real power or active power) of a motor is the electrical power that is actually consumed by the motor to perform work. It is calculated using the formula:

P = V × I × pf

Where:

  • P = Absorbed Power (watts)
  • V = Voltage (volts)
  • I = Current (amperes)
  • pf = Power Factor (dimensionless, between 0 and 1)

Example

If a motor operates at 220V with a current of 10A and has a power factor of 0.8, the absorbed power would be:

P = 220V × 10A × 0.8 = 1,760W

Applications

This calculator is useful for:

  • Estimating the power consumption of electric motors
  • Designing electrical systems to ensure proper capacity
  • Energy auditing and efficiency calculations
  • Motor selection for specific applications
