The ceiling fan mainly consists of fan blades, fan heads, suspension equipment, and speed controllers. The blades of ceiling fans are generally stamped with 1.5-2mm aluminum plates, mostly in a three leaf long strip structure. The fan head is the core component of a ceiling fan, consisting of a stator, rotor, ball bearings, and upper and lower end covers.

Nowadays, single-phase AC capacitor working motors are commonly used for ceiling fan motors. It differs from table fans and floor standing electric fans in that it adopts a closed outer rotor structure. The characteristic of this structure is that the stator is fixed in the middle of the motor, the outer rotor rotates around the stator, and then drives the connected fan head and shell to roll together. Installation of wind blades

On the fan head shell, follow the rotation of the fan head shell to supply air.

The speed controller of the ceiling fan is usually controlled by a reactance type speed control switch box, which is connected to each tap of the reactor separately to adjust the terminal voltage applied to the electric fan motor, so that the motor can obtain different torques at different voltages, and then obtain different speeds to achieve the purpose of speed regulation.

Nowadays, many households use electronic speed controllers to achieve stepless speed regulation of electric fans. When using it, first turn on the power and start the electric fan motor at high speed. After starting, users can adjust the air volume according to their needs.
