**About Brushless Motor Power Calculator (Formula)**

Using the Brushless Motor Power Calculator, you can determine how much input power is needed for a brushless motor to produce a desired output power at a given efficiency level. Input power, output power, and motor efficiency are all related using a simple formula.

**The formula used in the Brushless Motor Power Calculator is**

**Pi = Po/(E/100)**

**Where **

- Pi is the Brushless Motor Input Power (watts)
- Po is the output power (watts)
- E is the efficiency of the motor expressed as a percentage

According to the formula, brushless motors require a decimal input power equal to their output power divided by their efficiency. Input power and efficiency are used to determine the minimum power rating needed for brushless motors to achieve a desired output power, or to determine the expected output power of a given motor.

By entering the desired output power in watts along with the motor’s efficiency as a percentage, the Brushless Motor Power Calculator will calculate and display the required input power in watts.

The Brushless Motor Power Calculator allows users to easily calculate the power requirements of brushless motors, and it is a valuable tool for anyone who works with them. This calculator can help streamline the process and ensure optimal performance when designing a new motor system or troubleshooting an existing one.
