# Wind turbine angular velocity

## Description

The formula for the calculation of the angular velocity of a wind turbine rotor. The definition is according to the IEC 61400-2.

If a disc is rotating at 60 rpm is said to be rotating at either 2π rad/s or 1 Hz, where the former measures the angular velocity and latter reflects the number of revolutions per second.

## Variables

ω_{n} | Angular velocity (dimensionless) |

π | pi |

n | rotor speed in rounds per minute (dimensionless) |
