Description

Technical Field

[0001] This utility model relates to the field of wind turbine products, and in particular to a permanent magnet drive synchronous integrated motor for wind turbines. Background Technology

[0002] Currently, wind turbines are often installed in tea gardens and pastures. The structure of these wind turbines is shown in patent publication CN112922867A. The motors used in these wind turbines are generally AC asynchronous motors. Since permanent magnet synchronous motors have relatively high operating efficiency, some wind turbines used in tea gardens and other places are now starting to use permanent magnet synchronous motors. Patent publication CN221553013U discloses a permanent magnet synchronous motor that can be used in wind turbines. However, because there is no corresponding fixing structure on the casing of this type of permanent magnet synchronous motor, the permanent magnet synchronous motor disclosed in CN221553013U cannot directly replace the AC asynchronous motor in the wind turbine, and its adaptability is relatively poor. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a permanent magnet synchronous integrated motor for wind turbines.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A permanent magnet synchronous integrated motor for wind turbines includes a housing, a stator disposed inside the housing, a rotor rotatably disposed on the housing, a shaft disposed on the rotor, one end of the shaft being located outside the housing, and a connecting plate with an arcuate contact portion. The housing is cylindrical, the connecting plate is fitted together with the housing, and the arcuate contact portion on the connecting plate is in close contact with the outer wall of the housing. The connecting plate has mounting holes, and mounting holes are provided on both sides of the housing, with all mounting holes lying in the same plane.

[0006] In this type of permanent magnet synchronous integrated motor, a connecting plate is added. The arc-shaped contact part on the connecting plate is used to fit tightly against the outer wall of the housing. Since the connecting plate has mounting holes, it can be used to mate with fasteners such as screws or bolts. Therefore, by adding a connecting plate with mounting holes, this type of motor achieves convenient installation of the permanent magnet synchronous motor. Thus, this type of permanent magnet synchronous motor can be directly installed on the fan to replace the AC asynchronous motor, and has stronger installation adaptability.

[0007] Optionally, it also includes an end cap and a controller. The end cap is disposed on one side of the housing, and a sealed protective cavity is formed between the end cap and the housing. The controller is located in the protective cavity and is connected to a coil inside the housing.

[0008] The controller's function is to control the operating status of the entire motor. An end cover is installed on the housing, forming a protective cavity with the housing to protect the controller. This effectively integrates the motor and controller into a single unit, resulting in a more compact structure.

[0009] Optionally, the end cap is provided with heat dissipation fins.

[0010] The function of heat dissipation fins is to dissipate heat.

[0011] Optionally, the end cap is provided with a wiring sleeve.

[0012] The purpose of the wiring sleeve is to clamp and seal the cables entering and exiting the end cap.

[0013] Optionally, a side sealing plate may also be included, which is detachably mounted on the end cap.

[0014] The end cap has an observation port, and the side sealing plate is installed on the end cap with screws. The side sealing plate is used to block the observation port on the end cap.

[0015] Optionally, the connecting plate is provided with protrusions, there are two protrusions, each of which is provided with an arc surface, the arc surface is close to the outer wall of the shell, and there is a gap between the outer wall of the shell and the connecting plate.

[0016] Specifically, the arc surfaces on the two protruding blocks together form the arc contact area. These two arc surfaces fit snugly against the outer wall of the housing, allowing the housing to be suspended relative to the connecting plate. The gap between the outer wall of the housing and the connecting plate ensures rapid heat dissipation and prevents water accumulation between the connecting plate and the housing. The protruding blocks are integrally molded with the connecting plate, and the protruding blocks provide a certain degree of cushioning and shock absorption between the connecting plate and the housing.

[0017] Optionally, the mounting holes include oval mounting holes and circular mounting holes, and the oval mounting holes and circular mounting holes are distributed on both sides of the housing.

[0018] The presence of both oval and circular mounting holes ensures that the entire connecting plate can better adapt to different positions and different types of fastening needs.

[0019] The advantages of this invention are: it can be directly installed on the fan to replace the AC asynchronous motor, and its installation adaptability is stronger. Attached Figure Description

[0028] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a permanent magnet synchronous integrated motor for a fan includes a housing 2, a stator inside the housing 2, a rotor rotatably mounted on the housing 2, a rotating shaft 1 mounted on the rotor, one end of the rotating shaft 1 located outside the housing 2, and a connecting plate 6 with an arcuate contact portion. The housing 2 is cylindrical, and the connecting plate 6 is fitted together with the housing 2, with the arcuate contact portion of the connecting plate 6 adhering to the outer wall of the housing 2. The connecting plate 6 has mounting holes, and mounting holes are provided on both sides of the housing 2, with all mounting holes in the same plane.

[0029] In this type of permanent magnet synchronous integrated motor, a connecting plate 6 is added. The arc-shaped contact part on the connecting plate 6 is used to fit tightly against the outer wall of the housing 2. Since the connecting plate 6 has mounting holes, it can be used to cooperate with fasteners such as screws or bolts. Therefore, by adding the connecting plate 6 with mounting holes, this type of motor achieves convenient installation of the permanent magnet synchronous motor. Thus, this type of permanent magnet synchronous motor can be directly installed on the fan to replace the AC asynchronous motor, and has stronger installation adaptability.

[0030] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, it also includes an end cap 3 and a controller. The end cap 3 is disposed on one side of the housing 2, and a sealed protective cavity is formed between the end cap 3 and the housing 2. The controller is located inside the protective cavity and is connected to the coil inside the housing 2.

[0031] The controller's function is to control the operating status of the entire motor. An end cover 3 is installed on the housing 2, and the end cover 3 and the housing 2 form a protective cavity, which protects the controller. At the same time, it is equivalent to integrating the motor and controller into one unit, making the entire structure more compact.

[0032] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, heat dissipation fins 301 are provided on the end cover 3.

There are two protrusions 7, and each protrusion 7 is provided with an arc surface 701. The arc surface 701 is close to the outer wall of the housing 2, and there is a gap between the outer wall of the housing 2 and the connecting plate 6.

[0039] Specifically, the arc surfaces 701 on the two protruding blocks 7 together form an arc contact part. The two arc surfaces 701 are close to the outer wall of the housing 2, realizing the suspended installation of the housing 2 relative to the connecting plate 6. The gap between the outer wall of the housing 2 and the connecting plate 6 ensures that the housing 2 can dissipate heat quickly and prevents water accumulation between the connecting plate 6 and the housing 2. The protruding blocks 7 are integrally formed with the connecting plate 6, and the protruding blocks 7 can play a certain role in buffering and shock absorption between the connecting plate 6 and the housing 2.
