Description

Technical Field

[0001] The utility model relates to the technical field of motor equipment, in particular to an integral annular magnetic tile and a motor with the magnetic tile. Background Art

[0002] The magnetic tiles used as stators in existing motors are almost all multi-block in structure. Whether they are inner or outer arcs or square in shape, they will inevitably have poor magnetic field consistency. At the same time, due to the multi-block structure, the degree of eccentricity is difficult to control. Therefore, most of the current motor magnetic tile structures will cause the motor to vibrate and have noise problems, thereby affecting the performance of the motor. Moreover, due to the block-type magnetic tiles, it is very difficult to increase the area of ​​the magnetic field, which limits the use scenarios of the motor.

[0003] The prior art has the following deficiencies:

[0004] 1. Poor magnetic field consistency: The multi-block magnetic tile structure commonly used in current motors (whether inner and outer arcs or squares) makes it difficult to ensure the consistency and uniform distribution of the magnetic field. This inconsistency directly affects the operating efficiency and stability of the motor, which is a major defect of the existing technology.

[0005] 2. Structural eccentricity and vibration noise: The assembly of multiple magnetic tiles often leads to eccentricity problems, which are difficult to accurately calibrate, causing the motor to generate additional vibration and noise during operation. This not only reduces the working performance of the motor, but also increases energy consumption and affects the use environment.

[0006] 3. Limited scalability: The limitations of the traditional block-type magnetic tile design make it very difficult to increase the magnetic field area and adjust the magnetic field layout, which directly limits the improvement of motor performance and the expansion of application scenarios, especially in situations where high power output or specific magnetic field configuration is required.

[0007] 4. Technical challenges and application limitations: Existing technologies have not been able to effectively solve the complexity and cost issues of motor magnetic tile structures during manufacturing, installation and maintenance. In particular, for motor applications that pursue high efficiency, low noise and high stability, the shortcomings of existing magnetic tile structures are particularly significant.

[0008] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0009] In view of the problems existing in the prior art, the utility model provides an integral annular magnetic tile and a motor having the magnetic tile.

[0010] To achieve the above purpose, the specific scheme of the utility model is as follows:

[0011] The utility model provides an integral circular magnetic tile, comprising:

[0012] The outer wall is sleeved on the inner wall to form an integrated structure;

[0013] The outer side wall and the inner side wall are composed of arc segments and form a concentric structure;

[0014] By adjusting the magnetization method, a multi-lobed, evenly arranged magnetic field region is formed, the number of magnetic field regions is an even number, and occupies more than two-thirds of the total area of ​​the magnetic tile;

[0015] In addition, the magnetization method is adjusted to achieve a vertical or oblique distribution of the magnetic field area.

[0016] Furthermore, the outer side wall and the inner side wall are composed of arc surfaces consisting of a single full circle, two semicircular arcs or multiple small arcs.

[0017] Furthermore, the outer side wall is formed by splicing a plurality of continuous planes along the circumferential direction.

[0018] Furthermore, the geometric centers of the outer wall and the inner wall are kept concentric.

[0019] Furthermore, the magnetic tile forms magnetic field regions with an even number of lobes, including 4 lobes, 6 lobes, and 8 lobes, through magnetization. These magnetic field regions are evenly distributed along the circumference, and there is no magnetic field overlap between the magnetic field regions.

[0020] Furthermore, by adjusting the magnetization method on the magnetic tile, the direction of the magnetic field area is parallel to the axis of the magnetic tile or has an inclination angle of 15° to 45° with the axis of the magnetic tile.

[0021] Furthermore, two or more magnetic tiles are connected end to end and bonded in series to maintain the consistency of the overall magnetic field direction after the series connection, so as to extend the length of the magnetic tile and expand the magnetic field area.

[0022] The utility model also provides a motor, comprising a rotor and a stator formed by the integral annular magnetic tiles, wherein the rotor is arranged in the middle of the stator.

[0023] Furthermore, a shell is sleeved on the outer side of the stator.

[0024] The technical solution of the utility model has the following beneficial effects:

[0025] 1. Improve the consistency and uniformity of the magnetic field: Through the integral circular ring structure and the carefully designed magnetization method, the magnetic tile can form a uniformly distributed multi-petal magnetic field area, ensuring the consistency and high uniformity of the magnetic field inside the motor, which directly improves the operating efficiency and stability of the motor.

[0026] 2. Reduce vibration and noise: Due to the optimization of magnetic field distribution and the improvement of overall structural design, the utility model effectively reduces the vibration phenomenon of the motor during operation, and the motor noise level is significantly reduced, which improves the quietness of the motor operation and the user experience.

[0027] 3. Convenience of expanding the magnetic field area: By simply connecting two or more integral circular magnetic tiles in series, the magnetic field area can be easily expanded without sacrificing the consistency of the magnetic field direction, providing the motor with a more flexible magnetic field design space to adapt to more diverse performance requirements and application scenarios.

[0028] 4. Enhanced motor performance: Combining the above-mentioned improvement measures, the utility model significantly enhances the overall performance of the motor, including but not limited to improving the energy efficiency ratio, increasing the output power, and extending the service life, laying the foundation for the application of the motor in fields with high performance requirements.

[0029] 5. Broaden the application scenarios: By solving the limitations of the traditional magnetic tile structure, the motor of the utility model can better adapt to special application scenarios that have strict requirements on magnetic field control accuracy and noise control, such as precision instruments, electric vehicles, aerospace and other high-end fields.

[0030] 6. Simplified manufacturing and maintenance: The integrated design simplifies the production process and assembly steps of the magnetic shoe, which may reduce manufacturing costs and facilitate maintenance, which is conducive to reducing the overall cost of ownership of motor products in the long run.

[0048] Combination Figure 1-Figure 7As shown, the utility model provides an integral circular magnetic tile, comprising: an outer wall 2 is sleeved on an inner wall 1 to form an integral structure; the outer wall 2 and the inner wall 1 are composed of arc segments and form a concentric structure; by adjusting the magnetizing method, a multi-petal, evenly arranged magnetic field area 5 is formed, the number of magnetic field areas 5 is an even number, and occupies more than two-thirds of the total area of ​​the magnetic tile; in addition, the magnetizing method is adjusted to achieve a vertical or oblique distribution of the magnetic field area 5.

[0049] The outer side wall 2 and the inner side wall 1 are composed of arc surfaces consisting of a single full circle, two semicircular arcs or multiple small arcs.

[0050] The outer side wall 2 is formed by splicing a plurality of continuous planes along the circumferential direction.

[0051] The outer wall 2 and the inner wall 1 are kept concentric with each other in geometric center.

[0052] The magnetic tiles are magnetized to form magnetic field regions 5 with an even number of lobes, such as 4 lobes, 6 lobes, and 8 lobes. These magnetic field regions 5 are evenly distributed along the circumference, and there is no magnetic field overlap between the magnetic field regions 5 .

[0053] By adjusting the magnetization mode on the magnetic tile, the direction of the magnetic field region 5 is parallel to the axis of the magnetic tile or is inclined at an angle of 15° to 45° to the axis of the magnetic tile.

[0054] The two or more magnetic tiles are connected end to end and glued in series to maintain the consistency of the overall magnetic field direction after the series connection, so as to extend the length of the magnetic tile and expand the magnetic field area 5.

[0055] The utility model also provides a motor, comprising a rotor 3 and a stator composed of the integral annular magnetic tiles, wherein the rotor 3 is arranged in the middle of the stator.

[0056] The outer side of the stator is also covered with a shell 4.

[0057] The principle of this utility model is as follows:

[0058] Overall structural design: The integral circular magnetic tile is composed of an outer wall 2 and an inner wall 1 to form an integral structure. Both walls are designed with arc segments to form a concentric structure. This design abandons the traditional splicing method of multiple magnetic tiles and improves the integrity and stability of the magnetic tile structure.

[0059] Formation of magnetic field area 5: Through specific magnetization technology, the integral annular magnetic tile can be set to form a multi-petal magnetic field area 5, which is usually an even number, such as 4 petals, 6 petals, 8 petals, etc., evenly distributed on the circumference. The boundaries between each magnetic field area 5 are clear, and there is no cross-magnetic field distribution, which ensures the precise control of the magnetic field.

[0060] Magnetic field direction control: The adjustment of the magnetization method can not only control the number and layout of the magnetic field regions 5, but also change the direction of the magnetic field to make it appear vertical or oblique. This means that by changing the magnetization parameters, the distribution pattern of the magnetic field can be flexibly adjusted to meet different motor design requirements and performance optimization goals.

[0061] Series expansion: In order to further expand the magnetic field area 5 of the motor, the utility model allows two or more integral circular magnetic tiles to be connected in series by connecting them end to end and gluing them together. During the series connection process, the magnetic field directions of each magnetic tile are ensured to be consistent, which not only increases the effective coverage of the magnetic field, but also maintains the consistency and uniformity of the magnetic field.

[0062] Improved performance: The design and operating mechanism of the integrated ring magnet fundamentally improves the magnetic field distribution of the motor, reduces vibration and noise caused by uneven magnetic field, and thus improves the operating efficiency and performance of the motor. At the same time, by simply expanding the magnetic field area5, the motor can perform better in a wider power range and application environment.

[0063] In summary, this patent achieves precise control and optimization of the motor's magnetic field through an innovative integrated circular magnetic tile design combined with a flexible magnetizing strategy and magnetic tile series connection technology, improves the motor's performance indicators, expands the motor's application range, and reflects progress and innovation in the field of motor technology.
