Description

Technical Field

[0001] This utility model relates to the field of iron core structure technology, specifically a high-stability low-temperature iron core structure. Background Technology

[0002] The stator core, also known as the stator iron core, is the core component of the stator of an electric motor or generator. It is mainly made of stacked silicon steel sheets. The inner circle of the stator core has evenly distributed slots for embedding the stator windings.

[0003] In certain specific situations, motors need to operate in low-temperature environments. Therefore, the stator core, as one of the core components of the motor, also needs to operate under low-temperature conditions. This can result in a large temperature difference between the core and the surrounding environment, leading to thermal stress. Generally, by setting a protective plate on the outside of the core as a buffer layer, the impact of this temperature difference on the core can be reduced. For example, a skewed stator core structure disclosed in patent number CN219420391U uses a rubber plate and spring to insulate heat while absorbing external mechanical vibration or impact, protecting the core from damage. However, this structure is connected between the spring and the rubber plate, which poses a certain risk of loosening and may also transmit the vibration or impact of the core to the rubber plate through the spring, thereby affecting the stability of the entire system. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable low-temperature iron core structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability low-temperature iron core structure, comprising an iron core body, fixing teeth, winding grooves, and main silicon steel sheets. The iron core body is formed by uniformly stacking main silicon steel sheets, and the external connections between the main silicon steel sheets are uniformly fixed by clamping fasteners. Fixing teeth are uniformly distributed inside the iron core body, and winding grooves are formed in the iron core body between the fixing teeth. Protective plates are uniformly distributed on the outer side of the iron core body, and the protective plates are uniformly connected to the iron core body by elastic buffers. A sleeve is provided at the center of each elastic buffer, and a support core column is embedded inside each sleeve.

[0006] Preferably, vertical grooves are uniformly formed on the outer side wall of the core body, and reinforcing ribs are embedded in the interior of each vertical groove, with the reinforcing ribs radially distributed along the outer side wall of the core body.

[0007] Preferably, the fixing teeth have slots on both sides, and the slots are U-shaped.

[0008] Preferably, the protective plate has an arc-shaped cross-section, and all protective plates are made of rubber.

[0009] Preferably, the elastic buffers are all made of rubber, and the two ends of the elastic buffers are connected to the outer wall of the core body and the inner wall of the protective plate through the first connecting part and the second connecting part, respectively.

[0010] Preferably, the elastic buffer body has uniformly formed cavities inside, and the cavities are distributed in a concentric circle structure around the supporting core column.

[0011] Preferably, auxiliary silicon steel sheets are evenly spaced between the main silicon steel sheets, and the auxiliary silicon steel sheets are pre-stamped with reserved grooves during stamping, and resistance wires are provided inside the reserved grooves.

[0012] Preferably, the resistance wires are all embedded in the reserved slots, and the gap between the reserved slots and the resistance wires is uniformly filled with thermally conductive epoxy resin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-stability low-temperature iron core structure consists of an iron core body, main silicon steel sheets, an elastic buffer, and a protective plate. The iron core body is made of stacked main silicon steel sheets. A protective plate, made of rubber, is evenly distributed on the outer side of the iron core body, effectively reducing heat exchange between the iron core body and the external environment and maintaining the stable temperature of the iron core body.

It is also highly adaptable to the environment and is not easily affected by external factors such as temperature and humidity. Compared with springs, it is softer and more uniform, and can provide a more stable protective effect. The support core column in the central position of the elastic buffer can provide additional structural support, enhancing the overall stability and strength of the elastic buffer. Especially when subjected to external forces, the support core column can effectively prevent the elastic buffer from undergoing excessive deformation or collapse, maintaining the integrity of its shape and structure.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 The present invention provides an embodiment of a high-stability low-temperature iron core structure, comprising an iron core body 1, a fixing tooth 2, a winding groove 3 and a main silicon steel sheet 9. The iron core body 1 is formed by uniformly stacking the main silicon steel sheets 9, and the external connections between the main silicon steel sheets 9 are uniformly fixed by clamping fasteners 7.

[0022] Auxiliary silicon steel sheets 19 are evenly spaced between the main silicon steel sheets 9, and the auxiliary silicon steel sheets 19 are pre-stamped with reserved slots 16 during stamping, and resistance wires 17 are provided inside the reserved slots 16. Lead-out terminals are provided at the edge or end of the iron core body 1 to facilitate connection with an external power source.

[0023] When the resistance wire 17 is energized, it generates heat. In conjunction with the temperature control system of the equipment, it can maintain the iron core body 1 within a suitable working temperature range in a low-temperature environment, thereby maintaining its good physical and electromagnetic properties and preventing the iron core body 1 from losing magnetic permeability and mechanical strength due to the low-temperature environment.

[0024] All resistance wires 17 are embedded in the reserved slots 16, and the gap between the reserved slots 16 and the resistance wires 17 is uniformly filled with thermally conductive epoxy resin 18 to ensure efficient heat conduction.

[0025] The core body 1 has evenly distributed fixing teeth 2 inside, and winding grooves 3 are formed in the core body 1 between the fixing teeth 2 to provide space for winding installation, so that the winding can be tightly and orderly wound on the core body 1.

[0026] The fixed tooth 2 has slots 6 on both sides, and the slots 6 are U-shaped, which makes it easy to embed the wire into the slots 6, fix the position of the winding, and improve the stability of the winding during motor operation.

[0027] The outer side of the core body 1 is uniformly distributed with protective plates 4. The cross-section of the protective plates 4 is arc-shaped and the protective plates 4 are all made of rubber material, which has a low thermal conductivity, which can effectively reduce the heat exchange between the core body 1 and the external environment and maintain the temperature stability of the core body 1.

[0028] The protective plate 4 and the iron core body 1 are evenly connected by elastic buffers 10. The elastic buffers 10 are all made of rubber, and the two ends of the elastic buffers 10 are connected to the outer wall of the iron core body 1 and the inner wall of the protective plate 4 through the first connecting part 14 and the second connecting part 15, respectively.

[0029] The elastic buffer 10 has good elasticity and toughness, which can absorb external mechanical vibration or impact, protect the iron core body 1 from damage, and absorb thermal stress to prevent the iron core body 1 from deforming or cracking due to thermal expansion and contraction.

[0030] The elastic buffer 10 is not prone to performance degradation during long-term use and can maintain stable buffering performance. It is also highly adaptable to the environment and is not easily affected by external factors such as temperature and humidity. Compared with springs, it is softer and more uniform, and can provide a more stable protective effect.

[0031] Each elastic buffer 10 has a sleeve 12 at the center of its interior, and each sleeve 12 has a support core 13 embedded inside it.

[0032] It can provide additional structural support, enhance the overall stability and strength of the elastic buffer 10, especially when subjected to external forces, the support core column 13 can effectively prevent the elastic buffer 10 from undergoing excessive deformation or collapse, and maintain the integrity of its shape and structure.

[0033] The elastic buffer 10 has uniformly opened cavities 11 inside, and the cavities 11 are distributed in a concentric circle structure around the supporting core column 13.

[0034] This allows the elastic buffer 10 to absorb and disperse stress more effectively when subjected to external forces, thereby improving its elasticity and flexibility.

[0035] Vertical grooves 5 are evenly provided on the outer side wall of the core body 1, and reinforcing ribs 8 are embedded in the interior of each vertical groove 5. The reinforcing ribs 8 are radially distributed along the outer side wall of the core body 1. The reinforcing ribs 8 can resist shrinkage stress and prevent the core body 1 from deforming or cracking due to shrinkage at low temperature.

[0036] Working Principle: In this embodiment, the core body 1 has uniformly distributed fixing teeth 2 inside, and winding grooves 3 are formed between the fixing teeth 2 to provide space for winding installation, so that the winding can be tightly and orderly wound on the core body 1. Protective plates 4 are uniformly arranged on the outside of the core body 1. The protective plates 4 are made of rubber and have a low thermal conductivity, which can effectively reduce heat exchange between the core body 1 and the external environment and maintain the temperature stability of the core body 1. The protective plates 4 and the core body 1 are uniformly connected by elastic buffers 10. The elastic buffers 10 are all made of rubber and have good elasticity and toughness. They can absorb external mechanical vibration or impact, protecting the core body 1 from damage. At the same time, they can absorb thermal stress, preventing the core body 1 from deforming or cracking due to thermal expansion and contraction. The elastic buffers 10 are not prone to performance degradation during long-term use, can maintain stable buffering performance, and have strong environmental adaptability. It is not easily affected by external factors such as temperature and humidity. Compared with springs, it is softer and more uniform, and can provide better protection. The elastic buffer body 10 has a tube sleeve 12 in the center of the interior. The tube sleeve 12 is embedded with a support core column 13, which can provide additional structural support and enhance the overall stability and strength of the elastic buffer body 10. Especially when subjected to external force, the support core column 13 can effectively prevent the elastic buffer body 10 from deforming or collapsing too much, and maintain its shape and structural integrity. The iron core body 1 is made of stacked main silicon steel sheets 9. Auxiliary silicon steel sheets 19 are evenly spaced between the main silicon steel sheets 9. The auxiliary silicon steel sheets 19 have reserved grooves 16 during stamping. The reserved grooves 16 are all equipped with resistance wires 17, which can maintain the iron core body 1 within a suitable working temperature range in low temperature environment, thereby maintaining its good physical and electromagnetic properties and preventing the iron core body 1 from losing magnetic permeability and mechanical strength due to low temperature environment.
