Description
Technical Field
[0001] This utility model belongs to the field of motor component technology, and more specifically, it relates to a high-efficiency and energy-saving stator core using combined silicon steel sheets. Background Technology
[0002] High-efficiency and energy-saving stator cores using composite silicon steel sheets are core components used in electric motors. Their key feature is that the composite design of silicon steel sheets improves motor efficiency and reduces energy consumption. The composite splicing makes the arrangement of silicon steel sheets more aligned with the magnetic field direction, reducing magnetic resistance, hysteresis loss and eddy current loss. However, the commonly used traditional composite cores may have insufficient structural stability after assembly. Therefore, there is a need for a new type of high-efficiency and energy-saving stator core using composite silicon steel sheets. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a high-efficiency and energy-saving stator core using composite silicon steel sheets, thereby solving the problem that existing traditional composite cores may exhibit insufficient structural stability after assembly.
[0004] This utility model discloses a high-efficiency and energy-saving stator core using composite silicon steel sheets, achieved through the following specific technical means:
[0005] A high-efficiency and energy-saving stator core using composite silicon steel sheets includes silicon steel sheets, fastener one, and fastener two;
[0006] The silicon steel sheet has positioning grooves and positioning components A on both sides, and positioning component A is movably locked inside the positioning groove. The silicon steel sheet has two sets of round holes. The upper end of the fixing component one has six sets of grooves, and eight sets of positioning rods are fixedly connected inside the lower end of the fixing component one. The upper outer side of the positioning rods is threaded. The fixing component two is placed on the upper side of the fixing component one, and the fixing component two has eight sets of round holes. A set of positioning tubes is fixedly connected inside the eight sets of round holes on the fixing component two, and a set of internally threaded tubes is movably locked inside the eight sets of positioning tubes.
[0007] Furthermore, the positioning grooves on the four sets of silicon steel sheets cooperate with the positioning component A, and are assembled into a single-layer iron core after being spliced in a ring. The multiple layers of single-layer iron cores are vertically stacked inside the fixing component one, and the positioning rod is inserted into the round hole on the silicon steel sheet.
[0008] Furthermore, each of the two sets of circular holes in the silicon steel sheet is connected to a set of anti-slip sleeves, with the inner surface of the anti-slip sleeves tightly attached to the outer surface of the positioning rod.
[0009] Furthermore, the outer side of the second fixing member is provided with six sets of positioning members B, and the six sets of positioning members B are movably engaged in the six sets of grooves at the upper end of the first fixing member.
[0010] Furthermore, the inner threads of the eight sets of internally threaded tubes are threadedly connected to the outer threads at the top of the positioning rod, and a shock-absorbing pad is provided at the bottom of the internally threaded tube.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. By setting an internally threaded tube, this utility model facilitates the connection between the internal thread and the outer thread at the top of the positioning rod. A shock-absorbing pad is provided at the bottom of the internally threaded tube, which tightly connects the first and second fixing parts together, forming a strong clamping force on the multi-layer silicon steel sheet core and ensuring a compact core structure.
[0013] 2. This utility model sets up silicon steel sheets, with positioning grooves and positioning parts A on both sides of the silicon steel sheets. This makes it easier to use positioning parts A to be snapped into the positioning grooves, so that four sets of silicon steel sheets can be spliced together in a ring to form a single-layer iron core. This design facilitates the assembly of silicon steel, ensures the shape accuracy of the single-layer iron core, and also helps to optimize the magnetic circuit, reduce magnetic resistance, and reduce magnetic loss.
[0014] 3. This utility model features anti-slip sleeves. Two sets of round holes in the silicon steel sheet are connected to a set of anti-slip sleeves, and the inner surface of the anti-slip sleeves is in close contact with the outer surface of the positioning rod. This helps to prevent the silicon steel sheet from sliding on the positioning rod, increases the stability when the iron core is stacked, and can also reduce vibration and noise to a certain extent.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example:
[0023] As attached Figure 1 To be continued Figure 5 As shown:
[0024] This utility model provides a high-efficiency and energy-saving stator core using combined silicon steel sheets, including silicon steel sheet 1, fastener 1 4, and fastener 2 5;
[0025] The silicon steel sheet 1 has positioning grooves and positioning parts A2 on both sides, and the positioning parts A2 are movably locked inside the positioning grooves. The silicon steel sheet 1 has two sets of round holes. The upper end of the fixing part 1 4 has six sets of grooves, and eight sets of positioning rods 9 are fixedly connected inside the lower end of the fixing part 1 4. The upper outer side of the positioning rods 9 is threaded. The fixing part 2 5 is placed on the upper side of the fixing part 1 4, and has eight sets of round holes. A set of positioning tubes 8 are fixedly connected inside the eight sets of round holes on the fixing part 2 5, and a set of internally threaded tubes 7 are movably locked inside the eight sets of positioning tubes 8.
[0026] Among them, such as Figure 2 and Figure 4 As shown, the positioning grooves on the four sets of silicon steel sheets 1 cooperate with the positioning component A2, and after being spliced in a ring, they are combined to form a single-layer iron core. The multiple layers of single-layer iron cores are vertically stacked inside the fixing component 4, and the positioning rod 9 is inserted into the round hole on the silicon steel sheet 1. It is installed in the positioning groove by the positioning component A, so that the four sets of silicon steel sheets 1 can be spliced in a ring to form a single-layer iron core. This design facilitates the assembly of silicon steel 1, can ensure the shape accuracy of the single-layer iron core, and is also conducive to optimizing the magnetic circuit, reducing magnetic resistance, and reducing magnetic loss.
[0027] Among them, such as Figure 3 As shown, a set of anti-slip sleeves 3 are connected to the two sets of round holes of the silicon steel sheet 1. The inner surface of the anti-slip sleeve 3 is in close contact with the outer surface of the positioning rod 9. The two sets of round holes on the silicon steel sheet 1 are used to cooperate with the positioning rod 9 of the fixing component to realize the vertical stacking and fixing of the multi-layer iron core. The inner surface of the anti-slip sleeve 3 is in close contact with the outer surface of the positioning rod 9, which can prevent the silicon steel sheet 1 from sliding on the positioning rod 9, increase the stability when the iron core is stacked, and also reduce vibration and noise to a certain extent.
[0028] Among them, such as Figure 1 and Figure 2 As shown, the outer side of the second fixing member 5 is provided with six sets of positioning members B6, and the six sets of positioning members B6 are movably locked in the six sets of grooves at the upper end of the first fixing member 4. The six sets of grooves at the upper end of the first fixing member 5 are used to cooperate with the positioning members B6 of the second fixing member, so as to play the role of positioning and initial fixing between the upper and lower fixing members.
[0029] Among them, such as Figure 5 As shown, the inner threads of the eight sets of internally threaded tubes 7 are threadedly connected to the outer threads at the top of the positioning rod 9, and a shock-absorbing pad 10 is provided at the bottom of the internally threaded tube 7. The internally threaded tube 7 is threadedly connected to the positioning rod 9, which tightly connects the fixing part 1 5 and the fixing part 2 6 together, forming a strong clamping force on the multi-layer silicon steel sheet core, ensuring that the core structure is compact. The shock-absorbing pad 10 is set at the bottom of the internally threaded tube 7, which can reduce the energy loss caused by the vibration of the core during motor operation, reduce noise, and at the same time, it can also play a certain protective role for the silicon steel sheet 1, preventing damage caused by hard contact.
[0030] The specific usage and function of this embodiment are as follows:
[0031] like Figures 1 to 5 As shown, in this utility model, by using the positioning component A to be installed in the positioning groove, four sets of silicon steel sheets 1 can be spliced together in a ring to form a single-layer iron core. This design facilitates the assembly of silicon steel sheets 1, ensures the shape accuracy of the single-layer iron core, and is also conducive to optimizing the magnetic circuit, reducing magnetic resistance, and reducing magnetic loss. The internal threaded tube 7 is threadedly connected to the positioning rod 9, and the fixing component 1 5 and the fixing component 2 6 are tightly connected together, forming a strong clamping force on the multi-layer silicon steel sheet iron core, ensuring that the iron core structure is compact. The shock-absorbing pad 10 is set at the bottom of the internal threaded tube 7, which can reduce the energy loss caused by the vibration of the iron core during motor operation, reduce noise, and at the same time, it can also play a certain protective role for the silicon steel sheets 1, preventing damage caused by hard contact.
