Description

Technical Field

[0001] The utility model relates to the technical field of fan motors, in particular to a fan motor. Background Art

[0002] A fan motor is a motor specifically designed to drive the rotation of fan blades, mainly used to generate air flow to achieve the effects of ventilation, cooling or heating. The basic working principle of a fan motor is to convert electrical energy into mechanical energy. Through electromagnetic action, the rotor of the motor rotates, and then drives the fan blades to rotate.

[0003] Fan motors are widely used in various types of fans, including table fans, floor fans, ceiling fans, etc. They are not only used for ventilation and cooling in the home environment, but also widely used in air circulation systems in industrial, commercial and other places.

[0004] During the installation process of existing fan motors, the common method is to fix the motor housings with screws. In order to ensure the installation stability of the screws, the normal rotation direction of the fan is opposite to the rotation direction when loosening the screws. Therefore, during the continuous rotation of the fan, the screws will become tighter and tighter on the motor output. Without using tools such as wrenches, it is very difficult to disassemble them. And during long-term use, the screws and the motor housings will also rust, making it even more difficult to disassemble. Therefore, a fan motor that can ensure both installation stability and quick manual assembly is needed to improve the normal assembly efficiency. Summary of the Utility Model
