A ceiling fan hanger assembly includes a mount plate with a pair of plate extensions and a downrod having a pair of spaced downrod extensions. A connector bracket pivotally couples to the plate extensions to define a first pivot axis and pivotally couples to the downrod extensions to define a second pivot axis different than the first pivot axis.

An impeller is provided, including a metal housing, a shaft, and a plastic member. The metal housing has a shaft mounting hole. The inner surface of the shaft mounting hole includes three or more contact points, and the contact points are closer to the shaft than other portions of the inner surface of the shaft mounting hole. The shaft passes through the shaft mounting hole and is affixed by the contact points. The metal housing divides the shaft into an upper section, a middle section, and a lower section. The plastic member passes through the shaft mounting hole and is in contact with the middle section.

A heat dissipation fan of a magnetic suspension structure includes a fan frame, a fan blade assembly, a motor coil, a PCB, and an iron plate. The fan frame incudes a base portion and a circumferential wall portion. A central portion of the base portion is raised to form a central shaft. An assembling space is provided between an outer circumference of the central shaft and the circumferential wall portion. The motor coil is arranged in the assembling space and mounted to the central shaft and is electrically connected to the PCB to acquire electrical power. The fan blade assembly includes a hub portion including an axle core and blades extending radially from the hub portion. The fan blade assembly is rotatably mounted in the fan frame with the axle core mounted into a shaft formed in the central shaft. The rubber magnet encloses a circumference of the motor coil.

A condenser fan includes a lock hub and multiple blades that are fastened to the hub. Each of the blades includes six planes, each of which having variable parameters including pitch angle, sickle, chord length, and blade curve. For each embodiment of the evaporator fan, the blades are identically configured.

A rotary fan system with dual rotation axes, wherein a driving arm rotates about a first axis, and trailing arm rotates about a second axis.

Methods for manufacturing an impeller wheel assembly (e.g., an impeller wheel attached to one or more additional components) are provided. In one example, a method includes casting an impeller wheel without a hub feature in a mold and holding the cast impeller wheel in a fixed position using a holding plate during subsequent stages of fabrication (e.g., the addition of a shaft via friction welding).

In one aspect, a fan assembly is provided that can be manufactured while producing a significantly reduced amount of scrap material. More specifically, the fan assembly utilizes a hub ring and one or more hub strips to support a plurality of blades rather than a solid center disc or end disc used by some prior approaches. In another aspect, a method is provided that includes bending a member into an annular configuration and joining end portions of the member together to rigidly fix the member in the annular configuration. The rigid annular member may be used as an end ring, a hub ring, an orifice, or other component, while producing significantly less scrap material than traditional approaches.

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a ceiling fan mount with a dual axis gimble. The dual axis gimble can be received by a mounting bracket so that at least a first and second axis of rotation are provided to the ceiling fan assembly.
