Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a synchronous motor that is easy to install and produce. Background Art

[0002] In the prior art, as a widely used power equipment, the structural design of the synchronous motor is directly related to the convenience of installation, safety and maintenance efficiency. Traditionally, the power cord of the synchronous motor is mostly radially led out from the side wall of the motor housing. For example, an AC synchronous motor with patent application number CN201220203549.7 and a claw-pole permanent magnet synchronous motor stator and a speed reduction mechanism connection structure with patent application number CN201320121880.9 are all designed in this way. This design can meet the use requirements in most conventional installation scenarios. However, in the face of increasingly complex and compact mechanical equipment layout requirements, especially in an environment with limited installation space, this power cord layout method reveals its limitations.

[0003] Especially in narrow or special-shaped installation spaces, the side walls of the motor housing are in direct close contact with or embedded in the surrounding structure, resulting in the power lines extending radially from the side walls often facing the risk of being squeezed, which not only affects the insulation performance and service life of the line, but may also cause short circuit accidents due to squeezing, and even cause fire and other safety hazards in serious cases. In addition, unreasonable cable layout will increase the difficulty of installation and limit the flexibility and adaptability of the motor in specific application scenarios.

[0004] Therefore, how to optimize the lead-out method of the power cord while maintaining the original performance of the motor to adapt to a more compact and complex installation environment has become a technical problem that needs to be solved urgently. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] like Figures 1 to 6 As shown, the utility model discloses a synchronous motor that is easy to install and produce, including a casing 1 with an open end, a rotor assembly 2 and a stator assembly 3 are arranged in the casing 1, wherein the stator assembly 3 includes a first winding bobbin 31 and a second winding bobbin 32 that are fixed to each other, a claw pole assembly 33 is sleeved on the first winding bobbin 31 and the second winding bobbin 32, and a first winding 34 is wound on the first winding bobbin 31, and a second winding 35 is wound on the second winding bobbin 32. In addition, the first winding bobbin 31 is fixedly connected to a terminal 36 on a side away from the second winding bobbin 32, and the terminal 36 has three terminals. The first winding 34 and the second winding 35 are provided with a winding wire 37 electrically connected to the terminal 36. The specific connection method of the winding wire 37 and the terminal 36 is as follows. Figure 3As shown, the winding wire 37 on the second winding 35 passes over the first winding 34, and it should be noted that the length direction of the terminal 36 is coaxially arranged with the housing 1. In addition, the housing 1 is fixedly covered with a cover plate 4 at the open position, and the terminal 36 extends toward the cover plate 4. An access port 41 is opened between the cover plate 4 and the housing 1 at a position close to the terminal 36. The access port 41 facilitates the connection of the power cord with the terminal 36 and is connected to an external device from the access port 41. The position of the terminal 36 and the access port 41 of the utility model is reasonably arranged, which can avoid the power cord and the housing 1 being arranged radially, so that the side wall of the motor housing 1 is directly in close contact with the surrounding structure. When touching or embedding, the power cord is prevented from being squeezed, or the motor is difficult to install due to the power cord. The utility model optimizes the lead-out method of the power cord on the basis of maintaining the original performance of the motor, so that the motor can be easily installed in a more compact and complex environment. In addition, the terminal 36 can facilitate the connection of the winding wire 37 on the first winding 34 and the second winding 35, so that after the power cord is connected to the terminal 36, the winding wire 37 is connected to the power cord. Compared with directly connecting the winding wire 37 to the power cord, the winding wire 37 is first connected to the terminal 36, and then the power cord is connected to the terminal 36, which can be more convenient for automated production.

[0028] like Figure 2 As shown, the first winding bobbin 31 and the second winding bobbin 32 are both provided with a wire passing groove 38 on the side close to each other, and the wire passing groove 38 enables the winding wire 37 on the second winding 35 to pass through the side close to each other of the first winding bobbin 31 and the second winding bobbin 32 in an orderly manner, so as to pass over the first winding 34 and connect to the terminal 36. In addition, the first winding bobbin 31 also has a second wire passing groove 39 on one side of the terminal 36 for the winding wire 37 to pass through. The winding wire 37 on the first winding 34 and the second winding 35 is as shown in FIG. Figure 3 As shown, the winding wire 37 is connected to the terminal 36 via the second wire groove 39. The arrangement of the wire groove 38 and the second wire groove 39 improves the stability of the arrangement of the winding wire 37, making it less likely for the winding wire 37 to deviate.

[0030] Among them, the terminal 36 is also located between the cover plate 4 and the stator assembly 3. The casing 1 has a placement gap 11 on one side of the reduction assembly for accommodating the terminal 36. The utility model has a reasonable structure and a compact internal space, and the terminal 36 and the reduction assembly do not interfere with each other.

[0031] like Figure 6 As shown, the reduction assembly specifically includes a driving gear 61, a reduction double gear 62 and a reduction gear 63, wherein the reduction gear 63 is fixedly connected to the output shaft 5, the reduction double gear 62 is rotatably connected to the side of the cover plate 4 facing the inside of the casing 1, the driving gear 61 is fixedly connected to the rotating shaft 21, and the reduction double gear 62 is meshingly arranged between the driving gear 61 and the output reduction gear 63. When the rotor assembly 2 rotates, the rotating shaft 21 drives the driving gear 61, the driving gear 61 drives the reduction double gear 62, and the reduction double gear 62 drives the reduction gear 63 to rotate the output shaft 5. It should be noted that this is only one embodiment of the reduction assembly of the utility model, and the utility model can also be transmitted through other gear meshing forms.

[0032] like Figure 1 As shown, the housing 1 is integrally formed with a fixing support 12 at the open position, and the fixing support 12 is provided with a wire outlet notch 13 at a position corresponding to the access port 41. The wire outlet notch 13 is convenient for the power line to pass through, and the fixing support 12 can also be used to fix on a device that needs to be installed.
