Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and relates to a stator lamination, and particularly to a stator lamination for a reluctance motor. Background Technology

[0002] A reluctance motor is a type of synchronous motor that utilizes the torque generated by the non-uniform magnetic reluctance of the rotor. It is one of the simplest motors in terms of structure. Its principle is that magnetic flux always closes along the path of least magnetic reluctance. Therefore, when the iron core moves to the position of least magnetic reluctance, its main axis must coincide with the axis of the magnetic field.

[0003] The stator core of existing reluctance motors is formed by pressing together several stator laminations. After long-term operation, the gap between these stator laminations will increase, causing the magnetic field generated by the stator core to change, which in turn affects the rotation of the rotor. The motor is prone to local heating during operation, or the rotor and shaft may move and vibrate, resulting in noise. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a stator lamination for a reluctance motor that can be assembled with each other.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1 to 5As shown, this utility model can be implemented through the following example: A stator lamination for a reluctance motor includes a lamination body 1 and a lamination body 2. The lamination body 1 has a mounting hole 11, a fixing tube 3 is fixed in the mounting hole 11, a sliding rod 4 is installed in the fixing tube 3, a flat part 41 is provided on the sliding rod 4, a slot 411 is provided on the flat part 41, an installation groove 31 is provided in the fixing tube 3, a sliding plate 5 is installed in the installation groove 31, a locking block 51 is provided on the sliding plate 5, a top plate 42 is provided on the top of the sliding rod 4, a chamfer 1 52 is provided on the sliding plate 5, and a chamfer 2 421 is provided on the top plate 42.

[0021] The fixed tube 3 is interlocked with the sliding rod 4 and the sliding plate 5 to connect the stamping body 1 in series, preventing the spacing of the stamping body 1 from changing after long-term use; the upper flat surface 41 of the sliding rod 4 is designed to fit the sliding plate 5, making it easy for the sliding plate 5 to send the locking block 51 into the locking groove 411, and the flat surface 41 is designed to facilitate the user's visual rotation; the top plate 42 is used to squeeze the sliding plate 5 into the mounting groove 31, release the interlock between the sliding rod 4 and the sliding plate 5, and facilitate disassembly; the chamfer 1 52 and chamfer 2 421 are designed to facilitate the top plate 42 to squeeze the sliding plate 5 open.

[0022] like Figure 3 and Figure 4 As shown, a guide block 32 is provided inside the fixed tube 3, and a limiting plate 33 is provided on the rear end face of the fixed tube 3. The top plate 42 is sandwiched between the guide block 32 and the limiting plate 33. The guide block 32 is used to guide the top plate 42 to slide, and at the same time, it works with the limiting plate 33 to fix the top plate 42 inside the fixed tube 3, preventing the top plate 42 from sliding due to vibration during the operation of the motor, which would cause the jamming to be released.

[0023] like Figures 3 to 5 As shown, the top plate 42 has an opening 422 with the same shape as the guide block 32. The opening 422 facilitates the sliding of the top plate 42 within the fixed tube 3, enabling the top plate 42 to release the locking mechanism.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a fixing groove 34 is provided on the front end face of the fixing tube 3. A limiting strip 6 corresponding to the fixing groove 34 is installed on the limiting plate 33. A limiting rod 61 is provided on the limiting strip 6, and the limiting rod 61 passes through the limiting plate 33 and the top plate 42. After the stamping body is connected in series, the limiting strip 6 is inserted into the fixing groove 34, and the limiting strip 6 is limited by another fixing tube 3. The limiting rod 61 provided on the limiting strip 6 is used to fix the top plate 42 and the fixing tube 3 by passing through the limiting plate 33 and the top plate 42, so as to prevent the top plate 42 from rotating due to vibration and causing the jamming to be accidentally released.

[0025] like Figure 3As shown, the sliding plate 5 is provided with a guide rod 53, and a spring 7 is sleeved on the guide rod 53. The spring 7 is disposed between the sliding plate 5 and the mounting groove 31. The guide rod 53 is used to guide the spring 7 to push the sliding plate 5 to move, preventing the sliding plate 5 from deviating due to the spring 7's own deformation direction being incorrect; at the same time, the spring 7 provides the sliding plate 5 with a thrust to push the locking block 51 into the locking groove 411, preventing the locking between the locking groove 411 and the locking block 51 from being released.

[0026] like Figure 3 and Figure 4 As shown, the sliding plate 5 has a chamfer 54. The chamfer 54 is provided to avoid the sliding rod 4, so that the sliding rod 4 can come between the sliding plates 5 and engage the locking block 51 into the locking slot 411.

[0027] like Figure 2 and Figure 3 As shown, a limiting tube 8 is installed inside the second body 2 of the lamination, and a fixing plate 81 is provided next to the limiting tube 8. A bolt 9 passes through the fixing plate 81 and the second body 2 of the lamination. A sliding plate 5 is installed inside the limiting tube 8, so that the limiting tube 8 and the fixing tube 3 are snapped together. At the same time, the limiting tube 8 is fixed to the second body 2 of the lamination by the bolt 9, so that the fixing tube 3 is fixed to the second body 2 of the lamination, thus realizing the connection between the first body 1 and the second body 2 of the lamination.

[0028] The working principle of this utility model is as follows: The stamping body 1 is pressed together, so that the sliding rod 4 on the fixed tube 3 is engaged with the sliding plate 5 on another fixed tube 3. Then, the limiting tube 8 is fixed to the stamping body 2 by bolts 9. The stamping body 2 is then pressed onto the stamping body 1, so that the sliding plate 5 in the limiting tube 8 is engaged with the sliding plate 5, thus completing the assembly. When disassembling, a columnar object is inserted into the limiting tube 8 to push the sliding plate 5 in the limiting tube 8 open. Then, the stamping body 2 is taken out, and then the limiting strip 6 is taken out. The top plate 42 is rotated. When the opening 422 of the top plate 42 and the guide block 32 are engaged, the sliding rod 4 is pushed, so that the top plate 42 squeezes the sliding plate 5. The sliding plate 5 is moved away from the sliding rod 4 by the top plate 42, thereby releasing the engagement of the sliding rod 4. Then, the stamping body 1 is removed.

[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
