Description

Technical Field

[0001] This utility model belongs to the field of motor stator technology and relates to a stator stabilization structure for a linear motor. Background Technology

[0002] Stator stability is a key factor in ensuring the efficient and reliable operation of a motor. However, existing motor stators have some shortcomings in terms of stability. The stator core vibrates and generates noise under the influence of an alternating magnetic field, mainly due to core vibration and hysteresis losses caused by electromagnetic forces. The stator windings are subjected to thermal and mechanical stresses during operation, which can lead to insulation aging and winding deformation over long periods, thus affecting the motor's stability and lifespan. Conventional methods to address these shortcomings include using better materials and optimizing the design. Using high-permeability silicon steel sheets and high-quality insulation materials can reduce core vibration and winding insulation aging; precise machining and assembly techniques can improve the accuracy of the stator structure. However, these methods also have drawbacks. Using high-quality materials increases costs; optimized design may require complex calculations and simulations, increasing development cycles and costs; while enhanced maintenance can extend motor lifespan, it increases operating and maintenance costs and cannot fundamentally solve design and material defects. Therefore, there is an urgent need for a stator stabilization structure for linear motors to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stator stabilization structure for a linear motor, thereby solving the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a stator stabilization structure for a linear motor, comprising: a motor housing and an inner positioning frame, wherein a set of support frames for supporting the lower end of the motor housing is provided on the front and rear sides respectively, and a set of front sealing shells for sealing and fixing the inner sealing plate is provided on the left side of the motor housing, and a set of inner sealing plates for keeping the drive end side sealed is provided on the inner side of the front sealing shell.

[0005] The inner sealing plate has a set of inner heat dissipation aluminum fins on its right side for conducting heat dissipation inside the motor housing. The stator is located inside the inner heat dissipation aluminum fins. The left end of the stator is bolted to the inner side of the inner heat dissipation aluminum fins and fits against each other. The outer side of the right end of the stator is bolted to the inner side of the connecting frame. The inner sealing plate has a set of front limit bearings for maintaining the movement limit connection of the drive head. The front limit bearings have a set of drive heads for driving the linear motor inside. When the motor is used, the stator is energized and forms a magnetic field to drive the rotor to rotate. The left and right sides of the stator are respectively connected and fixed to the inner heat dissipation aluminum fins and the connecting frame, which can fix the stator and reduce the instability caused by poor stator fixation during rotor rotation.

[0006] In a preferred embodiment, the inner side of the drive head is provided with a set of transmission shafts for providing rotational potential energy, and the drive head passes through the center of the front limiting bearing, wherein the limiting bearing is a sealed bearing.

[0007] In a preferred embodiment, the side where the drive head is located is the drive end, the front cross-section of the connecting frame is an isosceles trapezoidal structure, and the right cross-section of the inner heat dissipation aluminum fin assembly is an annular structure.

[0008] In a preferred embodiment, the internal heat dissipation aluminum fin assembly is provided in several groups, and the several groups of internal heat dissipation aluminum fin assemblies are spliced ​​together to form a set of internal heat dissipation aluminum fin assemblies, and the outer side of the internal heat dissipation aluminum fin assembly is in contact with the inner side of the motor housing.

[0009] In a preferred embodiment, a connecting frame is provided on the right side of the inner heat dissipation aluminum fin assembly to maintain its connection and fixation. The connecting frame is fixed to the inner heat dissipation aluminum fin assembly by bolts. A rotor is provided inside the stator to provide drive rotation. The rotor is located outside the middle position of the drive shaft. When the rotor rotates rapidly inside the stator, heat is generated in the conductors when current passes through the stator and rotor. This is because electrons encounter resistance when passing through the conductor, and this resistance causes energy to be converted into heat energy, thus heating the stator and rotor. When heat is generated between the rotor and the stator, the inner heat dissipation aluminum fin assembly comes into contact with the stator, allowing the inner heat dissipation aluminum fin assembly to directly transfer the heat from the stator, thereby improving the stability of the motor during long-term operation.

[0010] In a preferred embodiment, a set of rear limiting bearings for limiting the rotational position of the drive shaft is provided at the center of the right end of the connecting frame. The rear limiting bearings are connected to the outer side of the right end of the drive shaft. Several sets of inner and positioning inserts for fitting and positioning the motor housing are provided on the right side of the inner sealing plate.

[0011] In a preferred embodiment, the inner socket and the positioning socket are respectively fitted and positioned to the left side of the motor housing, and bolts are used to pass through the positioning socket and the motor housing to connect and fix them.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: by using the magnetic field formed by the stator after being energized to drive the rotor to rotate, the left and right sides of the stator are respectively connected and fixed to the inner heat dissipation aluminum fin group and the connecting frame, which can form a fixed effect on the stator. At the same time, during the rotor rotation, the instability caused by poor stator fixation can be reduced.

[0013] When current flows through the stator and rotor, heat is generated in the conductors. This is because electrons encounter resistance when passing through the conductors, and this resistance causes energy to be converted into heat energy, thus heating the stator and rotor. When heat is generated between the rotor and stator, the internal heat dissipation aluminum fins come into contact with the stator, allowing the internal heat dissipation aluminum fins to directly transfer the heat from the stator, thereby improving the stability of the motor during long-term operation.
