Description

Technical Field

[0001] This utility model relates to the field of fans, specifically to a fan motor. Background Technology

[0002] Traditional fan motors generate a lot of heat during operation, but the common motor structure makes it difficult to dissipate heat quickly, which can easily cause the motor to overheat and affect its lifespan. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a fan motor that can quickly dissipate heat, allowing the motor to operate for extended periods with lower temperatures, higher efficiency, and a longer lifespan.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A fan motor includes a motor housing and a motor installed inside the motor housing. The motor includes a lower motor housing, an upper motor housing, a stator coil, a coil, a rotor, a shaft, an upper cooling fan, and a lower cooling fan. The coil is installed inside the lower motor housing via the stator coil. The rotor, upper cooling fan, and lower cooling fan are disposed inside the coil via the shaft. The upper cooling fan, rotor, and lower cooling fan are sequentially mounted on the shaft, and the blades of the upper and lower cooling fans have opposite tilt angles. A limiting hole adapted to one end of the shaft is provided inside the lower motor housing, and the other end of the shaft passes through the upper motor housing.

[0006] Furthermore, the motor box is made of aluminum alloy profile and has heat dissipation holes on the back.

[0007] Furthermore, the lower housing of the motor and the upper housing of the motor are connected by bolts to form a mounting cavity for the stator coil, coil, rotor, shaft, upper cooling fan and lower cooling fan.

[0008] Furthermore, the upper cooling fan and the lower cooling fan are located on the upper and lower surfaces of the rotor, respectively.

[0009] Furthermore, the stator ring is made of silicon steel sheet, and its inner side is provided with a slot for installing the coil. The coil includes two coil rings and several coil posts disposed between the two coil rings. The coil posts are locked in the slot, and the two coils protrude from the stator ring.

[0010] The motor box of this utility model is made of die-cast aluminum alloy, which is not only aesthetically pleasing but also has good heat dissipation performance. With the front and rear heat dissipation fan blades installed at opposite angles, the heat dissipation efficiency can be further improved, preventing the motor from overheating. This allows the motor to be used for a long time with lower temperature, higher efficiency, and longer life. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-6As shown, this utility model provides a fan motor, including a motor housing 1 and a motor 2 and a motor controller (not shown) installed inside the motor housing 1. The motor 2 is installed inside the motor housing 1 and is limited by a cover plate (not shown). The motor 2 includes a lower motor housing 3, an upper motor housing 5, a stator coil 4, a coil 6, a rotor 7, a shaft 8, an upper cooling fan 9, and a lower cooling fan 10. The lower motor housing 3 and the upper motor housing 5 are connected by bolts to form the mounting structure of the stator coil 4, coil 6, rotor 7, shaft 8, upper cooling fan 9, and lower cooling fan 10. The motor is assembled in a cavity; the coil 6 is installed inside the lower housing 3 of the motor via the stator coil 4, and the rotor 7, the upper cooling fan 9 and the lower cooling fan 10 are arranged inside the coil 6 via the rotating shaft 8. The upper cooling fan 9, the rotor 7 and the lower cooling fan 10 are sequentially mounted on the rotating shaft 8, and the blades of the upper cooling fan 9 and the lower cooling fan 10 have opposite tilt angles, that is, the upper cooling fan 9 and the lower cooling fan 10 respectively adopt positive angle blades and negative angle blades; the lower housing 3 of the motor is provided with a limiting hole that matches one end of the rotating shaft 8, and the other end of the rotating shaft 8 is arranged through the upper housing 5 of the motor.

[0021] To further improve the heat dissipation performance of the fan motor, the motor box 1 is made of aluminum alloy profile and has heat dissipation holes on the back. The aluminum alloy profile has high thermal conductivity, which can quickly conduct heat away. At the same time, the material has good weather resistance, which can extend the service life of the motor box 1.

[0022] In this embodiment, to facilitate the installation of the coil, the stator ring 4 is made of silicon steel sheet, and a slot for installing the coil 6 is provided on its inner side. The coil 6 includes two coil rings and a plurality of coil posts disposed between the two coil rings. The coil posts are secured in the slot, and the two coils protrude from the stator ring 4.

[0023] To further ensure smooth motor operation and reduce operating noise, the coil 6 uses copper enameled wire with excellent insulation properties, and the shaft 8 undergoes a tempering heat treatment process to prevent rotor deformation during operation. Furthermore, the bearings of the shaft 8 utilize double ball bearings, which reduce operating noise and increase lubrication.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
