[0031] Please refer to Figures 1 to 5 The fan motor in the figure is designed with a driver 1, a first mounting plate 2, and a body 3; the driver 1 is used to install electronic control components and electrically control the body 3; the first mounting plate 2 is used to fix the entire fan motor; the body 3 is used as the main structure of the entire motor; the present application optimizes and innovates the entire structure of the fan motor so that it can be better applied to fans. In actual applications, the above components can be further optimized or other components can be added.

[0032] The driver 1 in the figure is an existing component, and the present application installs it on a first mounting plate 2, which provides space for the installation of the entire motor.

[0033] The first mounting plate 2 in the figure is designed with four square mounting ends 21 protruding outward at the outer edge position, and each mounting end 21 is designed with a mounting hole 211, so that it is easy to cooperate with the bracket and other components to achieve fixation on the fan hub. The center position of the first case plate is longitudinally extended with a protruding mounting portion 22 structure toward the upper and lower positions in the figure. The mounting portion 22 is hollow inside and has a keyway so that it can be assembled with the rotating shaft 51 in the body 3; in order to facilitate threading and installation, the mounting portion 22 is designed with a threading hole 221 and a mounting hole 211 structure. In order to form a firm matching relationship with the rotating shaft 51, the inner annular surface of the mounting portion 22 is fixed to each other by a cone shaft positioning method with the rotating shaft 51 of the body 3. In actual application, the number of mounting ends 21 can be adjusted according to the situation.

[0034] The body 3 in the figure is a structure of a permanent magnet synchronous motor, which mainly designs the first upper cover 31, the rotating shaft 51, the bearing 52, the first lower cover 32, the first shell 33 and other components. The first upper cover 31, the first shell 33 and the second lower cover 61 form the external structure of the entire body 3, and the rotating shaft 51 and the bearing 52 form the internal structure of the entire body 3. The functions of the above components can refer to the existing permanent magnet synchronous motor. The first upper cover 31 in the figure has a hole-shaped structure inside, so that it is convenient to configure the bearing 52 and the mounting portion 22 of the first mounting plate 2. In order to facilitate heat dissipation and strengthen the strength of the entire cover body, it can design a plurality of uniformly arranged first ribs 311 structures on the outer top surface of the top, and at the same time, it can also design a plurality of uniformly arranged second ribs 312 structures inside. The above rib structure is a conventional straight plate-like structure. The rotating shaft 51 in the figure is optimized from a traditional cylindrical structure to a conical structure, so that the surface where the rotating shaft 51 is assembled with the first mounting plate 2 is a conical match, and at the same time, the rotating shaft 51 is sleeved with the above bearing 52 at the position where it matches the first upper cover 31 and the first lower cover 32. The first shell 33 is hollow inside and is installed between the first upper cover 31 and the first lower cover 32 at both ends. In order to facilitate heat dissipation, multiple annular heat dissipation strip structures can also be designed on its outer surface. The first lower cover 32 adopts a hole-shaped structure inside to facilitate the placement of the bearing 52. The first lower cover 32 is arranged and installed relative to the first upper cover 31. At the same time, multiple fixing grooves 321 are evenly arranged on the surface that cooperates with the petiole. The above-mentioned fixing groove 321 is semicircular as a whole. Next to the fixing groove 321 is a screw hole for installing bolts. In this way, when the angle of the petiole needs to be adjusted, first loosen the bolt in the alignment position, then rotate and adjust the angle of the petiole, and then install the bolt. In order to cooperate with the installation of the petiole, a fixing block is configured on the above-mentioned fixing groove 321, and the fixing block also has a semicircular groove, so that the structure formed by the two grooves corresponds to the structure of the petiole.

[0035] Please refer to Figures 6 to 10The fan motor in the figure is designed with a driver 1, a second mounting plate 4, and a body 3; the functions of the above components can refer to the above embodiments. In practical applications, the above components can be further optimized or additional components can be added.

[0036] The driver 1 in the figure is an existing component, and the present application installs it on the second mounting plate 4, which provides space for the installation of the entire motor.

[0037] The second mounting plate 4 in the figure is also designed with four square mounting ends 21 protruding outward at the outer edge, and each mounting end 21 is designed with a mounting hole 211 for facilitating the installation of the entire motor, so that it can be fixed on the hub of the fan in conjunction with the existing bracket. The second mounting plate 4 extends in the direction toward the rotating shaft 51 to form a fixed portion 41 structure, and the fixed portion 41 adopts an internal hollow design, so that this position can match the middle and upper position of the rotating shaft 51 of the body 3 and the bearing 52, and at the same time, the inner surface of the fixed portion 41 can be fixed to the rotating shaft 51 of the body 3 in a tapered shaft positioning manner as described in the embodiment. The top of the second mounting plate 4 is also designed as a hollow hole structure, so that it penetrates the hollow integral body of the fixed portion 41.

[0038] The body 3 in the figure is a permanent magnet synchronous motor structure, which mainly designs a rotating shaft 51, a bearing 52, a second lower cover 61, and a second shell 62. The second mounting plate 4 replaces the design of the upper cover, and the second shell 62 in the figure is arranged inside the second mounting plate 4 and the second lower cover 61, so that the second lower cover 61 and the second mounting plate 4 are arranged oppositely. The second shell 62 adopts a hollow annular structure design. In order to facilitate the configuration of the bearing 52, a hole-shaped structure is designed inside the second lower cover 61. Like the above embodiment, the second lower cover 61 has a plurality of fixing grooves 321 structures for facilitating the installation of the fan blade handle. Each fixing groove 321 is a semicircular structure and is designed with a plurality of screw holes for mounting bolts next to it.
