Claims

[Scope of utility model registration request]

A rotor part is formed by a yoke provided with a magnet, blades provided on the outer periphery of the yoke, and a shaft serving as a rotating shaft, and a stator located inside the rotor part, an excitation coil, and the shaft. A stator section is formed by a bearing section that supports the shaft and a housing in which each of these components is attached, and a printed circuit board mounted with a drive circuit that rotationally drives the rotor section is provided inside the housing, and air flows from one side of the housing to the other. In a DC brushless fan motor having a wind tunnel serving as a flow path, a flange portion for mounting on a panel surface is formed on the housing in a direction perpendicular to the flow path except for the wind tunnel portion, and parallel to the flow path and different from the flange portion. A DC brushless fan motor characterized in that a mounting base is formed in a housing in a direction orthogonal to the housing.
