Abstract

A wind power generation unit, an electric motor, and an airflow delivery for an electric motor air gap are provided. The airflow delivery device for the electric motor air gap comprises an annular air distribution chamber, wherein the annular air distribution chamber is located at at least one end of the air gap, and the annular air distribution chamber has a delivery port facing the air gap so as to deliver a hot or cold airflow to the air gap. The annular air distribution chamber is arranged at an end part of the air gap, the required airflow is introduced into the annular air distribution chamber, and the annular air distribution chamber can output the accumulated airflow to the air gap, facilitating the airflow in flowing smoothly through the air gap, such that the flow of the air gap is relatively easy to control.
