A ceiling fan structure includes a mounting bracket, a hanging plate, a coupling, and a motor. The mounting bracket is fixed to a ceiling. The hanging plate has a top fixed to the mounting bracket. The top is formed with a recessed accommodating groove for accommodating a first electronic component. The coupling is connected to a bottom of the accommodating groove and extends downward. The coupling is connected with a support plate extending horizontally. The support plate is configured to support a second electronic component. The internal space of the ceiling fan structure is properly planned so that the components of the ceiling fan structure can be reasonably configured, so as to improve the efficiency of assembly.

A ceiling fan mount assembly having a downrod assembly with a downrod and a motor assembly comprising motor and including a motor shaft. The ceiling fan mount assembly further includes a downrod plate coupled to the downrod and a shaft coupler coupled to the motor shaft and coupled to the downrod plate, whereby coupling the downrod plate to the shaft coupler suspends the motor from the downrod.

A blower including a volute, a motor, a blower wheel, and a box. The motor is disposed on the volute. The motor includes a spindle, a rotor assembly, a stator assembly, a motor housing, a front-end cover, a rear-end cover and a capacitor. The rotor assembly is disposed on the spindle. The stator assembly and the motor housing are integrated and sleeved on the rotor assembly. The front-end cover and the rear-end cover are installed on the two ends of the motor housing, respectively. Two ends of the spindle are supported on the bearing of the front-end cover and the bearing of the rear-end cover, respectively. The front end of the spindle extends into the volute and is connected to the blower wheel. The capacitor is disposed in a cavity formed by the box and the rear-end cover.

A motor control system providing at least seventeen speed settings using industry standard control signals and an industry standard five pin speed connector. One speed monitoring pin transmits an output signal for monitoring the speed of the motor, and four speed setting pins receive input signals for setting the speed. One of the speed setting pins receives and decodes two binary states and two frequency states, thereby providing a total of thirty-two speed settings. A non-regulated isolated winding is added to an internal transformer to provide an internal isolated flyback power supply for the motor, thereby liberating a pin on the industry standard five pin speed connector to provide the fourth speed setting input pin. Transmission circuitry is associated with the speed monitoring pin, and the non-regulated isolated winding is used to provide a direct current bias to the transmission circuitry.

A fan and an electronic device are provided. The fan includes a hub, an outer frame surrounding the hub, and a plurality of blades connected between the hub and the outer frame. The outer frame includes a first side facing an air inlet of the fan, a second side facing an air outlet of the fan, and an inner wall between the first side and the second side. Each of the plurality of blades includes a first end connected to the hub and a second end connected to the outer frame. The second end includes a first region and a second region, the second region is connected to the inner wall. The first region extends from the second region and is disposed above the first side. A first notch is defined among the first regions of two adjacent blades and the first side.

A blower unit can include an outer housing, an inlet subassembly, a fan subassembly, an outlet subassembly, and a grommet. The outer housing can have an aperture extend along a first axis between first and second ends. The inlet subassembly can be received in the first end of the aperture. The fan subassembly can be received in the aperture adjacent to the inlet subassembly and include at least one wire. The outlet subassembly can be received in the second end. The grommet can be positioned between at least part of the second end and the outlet subassembly. The at least one wire can extend through the grommet. The grommet can seal against the at least one wire. The grommet can seal between the outer housing and the outlet subassembly.

A ceiling fan having a dual redundant motor mounting assembly for suspending a motor comprising a downrod, a hollow motor shaft suspending the motor from the downrod, a retaining pin extending through the hollow motor shaft, and a retaining rod coupled to the retainer pin for redundantly suspending the motor.
