Abstract: A rotating electrical machine includes an annular coil connection body provided coaxially with a stator. The coil connection body has, in a groove provided on a holder, an overhang portion for restricting an axial-direction movement of a terminal, and a positioning projection for restricting a radial-direction movement of the terminal. The positioning projection positions the terminal such that a part of the terminal overlaps the overhang portion in the axial direction. In this structure, when the terminal moves in a direction from a terminal holding portion toward a groove opening, the terminal comes into contact with a side surface of the overhang portion, whereby lifting and coming-off of the terminal can be prevented.

The second resin blocks at least a part of the plurality of holes reaching the first face.

Abstract: A problem to be solved by the present disclosure is to realize a fan unit capable of determining occurrence or non-occurrence of a backflow during operation. In a second unit, a second controller calculates front-rear differential pressure by substituting a rotation speed and a volume of air or a wind speed that can be acquired in real time into a relational expression. The relational expression derives, from two values of the rotation speed, the volume of air or the wind speed, and the front-rear differential pressure, the remaining one value. Then, the second controller determines that a backflow occurs if the calculated front-rear differential pressure is within a range that cannot occur under a normal condition. Therefore, the occurrence of a backflow can be detected without using an expensive pressure sensor or a directional wind speed sensor.
