    摘要: A portable fan assembly. The fan assembly includes a motor, a shaft rotatably driven by the motor and a plurality of fan blades coupled to the shaft and rotatable with the shaft. The fan assembly further includes a mounting mechanism that is configured to releasably mount the fan to a non-upwardly facing, horizontal flat surface without requiring modification of the surface.

    摘要: A fan includes an annular frame, a rail assembly, a driving member and blades. The blades are connected to the driving member. The driving member is electromagnetically movable along the magnetic levitation assembly that extends along an edge of the annular frame. The driving member does not contact the annular frame or the magnetic levitation assembly so that when the fan is used, the magnetic levitation assembly is energized to generate an electromagnetic force between the magnetic levitation assembly and the driving member to move the driving member along the edge of the annular frame to drive the blades to rotate. Therefore, the blades can be rotated without having to use any motor behind the annular frame, thereby reducing the volume of the fan.

    摘要: A motor including a rotating portion that is rotatable about a center axis that extends vertically and a stationary portion that rotatably supports the rotating portion. The stationary portion includes a stator facing at least a portion of the rotating portion in a radial direction, a base disposed axially below the stator, and a resin portion covering at least a portion of the stator, connecting the stator and the base. The base includes a recessed portion that is recessed downward in an axial direction and that accommodates at least a portion of the resin portion. The recessed portion includes an inner peripheral surface provided with an upper wall portion disposed axially above a portion of the resin portion.
