Description

Technical Field

[0001] This utility model relates to the field of generator set accessories technology, and more specifically, it relates to a stator core for generator set accessories. Background Technology

[0002] Generator set accessories refer to various components and equipment used for the operation, maintenance, and performance optimization of generator sets. These accessories include core components, which are key parts of the generator and engine and directly participate in energy conversion and power output. In addition, they also include control systems, cooling systems, lubrication systems, fuel systems, exhaust systems, and electrical systems. These accessories work together to ensure the efficient and stable operation of the generator set and extend the service life of the equipment.

[0003] Among these collaboratively operating systems and key components, the core components can be considered the "heart" of the generator set. Their performance directly affects the overall operating efficiency of the unit. Among the core components, the stator core occupies a crucial position. As the core hub for electromagnetic energy conversion, it provides a solid foundation for the efficient operation of the generator set with its unique characteristics of high permeability and low loss.

[0004] However, the ratio of the center hole to the outer diameter of the stator core is equally critical. If the ratio is too small, although it can increase the effective magnetic field area, it will restrict the flow of cooling medium, resulting in poor heat dissipation, increased leakage flux and eddy current losses, reduced efficiency, and affected unit stability and service life. In addition, the assembly and maintenance space is small, winding installation and maintenance are difficult, and maintenance costs and downtime are increased. Therefore, a stator core for generator set accessories is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stator core for generator set accessories.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stator core for generator set accessories, comprising a stator core body, a central through hole on the stator core body, a plurality of stator core teeth evenly arranged on the inner wall of the stator core body, the stator core teeth being evenly distributed along the annular axis, tooth grooves symmetrically arranged on the sidewalls of the stator core teeth, the tooth grooves having a V-shaped structure, a stator winding groove having a U-shaped structure being provided between two stator core teeth; the outer diameter of the stator core body is 2276mm, and the inner diameter of the stator core body is between 1904.6mm and 1905.4mm.

[0007] The present invention is further configured such that the stator core body is composed of multiple silicon steel sheets stacked together.

[0008] The present invention is further configured such that: a stator core shell is provided on the side wall of the stator core body, and the stator core shell is symmetrically provided with limiting members.

[0009] The present invention is further configured such that: the limiting member is provided with a limiting hole, the limiting hole being used to fix the component.

[0010] The present invention is further configured such that: a plurality of positioning holes are provided on the stator core outer shell, and the positioning holes are evenly distributed along the annular axis.

[0011] The present invention is further configured such that: the outer wall of the stator core body is provided with a plurality of positioning steel bars, and the positioning steel bars are snapped into the corresponding positioning holes.

[0012] The present invention is further configured such that the shape of the positioning steel bar is adapted to the shape of the positioning hole.

[0013] In summary, this application includes at least one of the following beneficial technical effects: while ensuring that the outer diameter of the stator core remains unchanged, by increasing the size of the inner diameter, the ratio of the central through hole of the stator core to the outer diameter of the core is increased, thereby increasing the heat dissipation area and providing more spacious space for assembly and maintenance operations.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] Please see Figures 1-5 The present invention provides the following technical solution:

[0023] Example 1, see Figures 1-5 A stator core for generator set accessories includes a stator core body 1, a central through hole 2 on the stator core body 1, and a plurality of stator core teeth 3 evenly arranged on the inner wall of the stator core body 1. The stator core teeth 3 are evenly distributed along the annular axis, and tooth grooves 31 are symmetrically arranged on the side walls of the stator core teeth 3. The tooth grooves 31 have a V-shaped structure, and a stator winding groove 4 with a U-shaped structure is arranged between two stator core teeth 3. The outer diameter of the stator core body 1 is 2276 mm, and the inner diameter of the stator core body 1 is between 1904.6 mm and 1905.4 mm.

[0024] Among them, the central through hole 2 allows the rotor to pass through the stator core body 1, which improves the flexibility of the structure and the ease of installation. The design of the stator core teeth 3 increases the magnetic reluctance of the motor, promotes the generation of magnetic field and the transmission of electromagnetic force. The V-shaped structure of the tooth slot 31 helps to fix the stator winding and ensures the stable installation of the stator coil, thereby improving the electrical performance of the motor. The stator winding slot 4 has a U-shaped structure for embedding the stator coil, which enhances the continuity of the magnetic path and improves the efficiency and power output of the motor.

[0025] In this invention, the outer diameter of the stator core body 1 is fixed at 2276 mm, while its inner diameter is within the range of 1904.6 mm to 1905.4 mm. In actual production, when the outer diameter of the stator core body 1 remains constant, the inner diameter of this component has a certain degree of variability and can be appropriately increased within the above range.

[0026] While ensuring that the outer diameter of the stator core 1 remains unchanged, the ratio of the central through hole 2 of the stator core to the outer diameter of the core is increased by increasing the inner diameter, thereby increasing the heat dissipation area and providing more spacious space for assembly and maintenance operations.

[0027] See Figures 1-5 Furthermore, the stator core body 1 is composed of multiple silicon steel sheets 11 stacked together.

[0028] Among them, the stator core body 1, composed of 11 stacked silicon steel sheets, has a stable and stronger structure, which can effectively resist the electromagnetic force and mechanical stress impact generated during motor operation, ensuring that it maintains the stability of its original shape and performance during long-term use.

[0029] See Figures 1-5 Furthermore, a stator core housing 5 is provided on the side wall of the stator core body 1, and limit members 52 are symmetrically provided on the stator core housing 5.

[0030] Among them, the stator core body 1 is the main magnetic circuit part of the motor, and the stator core shell 5 set on its side wall is used to protect and fix the stator core body 1, and enhance the stability of its overall structure.

[0031] See Figures 1-5 Furthermore, the limiting member 52 is provided with a limiting hole 53, which is used to fix the component.

[0032] The limiting hole 53 on the limiting member 52 is used to fix the components and ensure the stability and reliability of the components during the operation of the motor.

[0033] See Figures 1-5 Furthermore, the stator core outer shell 5 is provided with multiple positioning holes 51, which are evenly distributed along the annular axis.

[0034] The stator core housing 5 has multiple evenly distributed positioning holes 51 on its outer wall, which provide positioning references for the assembly process and ensure the consistency and stability of the installation.

[0035] See Figures 1-5 Furthermore, the outer wall of the stator core body 1 is provided with multiple positioning steel bars 6, which are snapped into the corresponding positioning holes 51.

[0036] See Figures 1-5 Furthermore, the shape of the positioning steel bar 6 is adapted to the shape of the positioning hole 51.

[0037] Among them, the multiple positioning steel bars 6 provided on the outer wall of the stator core body 1 are adapted to the shape of the positioning holes 51 and can be firmly locked in the corresponding positions, thereby realizing the precise positioning and reliable connection between the stator core body 1 and the stator core outer shell 5.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
