具体实施方式Detailed ways
为了使本领域的技术人员更好的理解本发明的技术方案，下面结合附图1-8和具体实施方式对本发明作进一步的详细说明。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to FIGS. 1-8 and specific embodiments.
实施例一Example one
如图1所示，本发明提供了一种混合磁通复合结构盘式电机1000，其中，混合磁通复合结构盘式电机1000包括前定子组件100、中间定子组件200和转子组件300。As shown in FIG. 1, the present invention provides a hybrid magnetic flux composite structure disk motor 1000, wherein the hybrid magnetic flux composite structure disk motor 1000 includes a front stator assembly 100, an intermediate stator assembly 200 and a rotor assembly 300.
如图2所示，转子组件300包括导磁转子支架30、前端面永磁体31和中间永磁体32，前端面永磁体31和中间永磁体32均安装在导磁转子支架30上，且中间永磁体32环绕前端面永磁体31设置。具体地，前端面永磁体31和中间永磁体32的个数均为多个，且前端面永磁体31和中间永磁体32分别沿着不同的半径周向均布在导磁转子支架30上，中间永磁体32的分布半径大于前端面永磁体31的分布半径，即中间永磁体32环绕前端面永磁体31分布。As shown in Figure 2, the rotor assembly 300 includes a magnetically permeable rotor support 30, a front end permanent magnet 31 and a middle permanent magnet 32. The front end permanent magnets 31 and the middle permanent magnet 32 are both installed on the permeable rotor support 30, and the middle permanent magnet The magnet 32 is arranged around the permanent magnet 31 on the front end surface. Specifically, the number of front-end permanent magnets 31 and middle permanent magnets 32 are both multiple, and the front-end permanent magnets 31 and middle permanent magnets 32 are respectively evenly distributed on the permeable rotor support 30 along different radii and circumferential directions. The distribution radius of the magnet 32 is greater than the distribution radius of the front permanent magnet 31, that is, the middle permanent magnet 32 is distributed around the front permanent magnet 31.
前定子组件100与前端面永磁体31面对面设置，即前定子组件100的前定子铁芯10面向前端面永磁体31设置，以便于前定子组件100的前定子铁芯10与前端面永磁体31能够形成闭合的磁场回路。The front stator assembly 100 and the front permanent magnet 31 are arranged face to face, that is, the front stator iron core 10 of the front stator assembly 100 is arranged facing the front permanent magnet 31, so that the front stator iron core 10 of the front stator assembly 100 and the front permanent magnet 31 A closed magnetic field loop can be formed.
中间永磁体32置于中间定子组件200的定子槽20内，具体地，中间定子组件200的定子槽20为通槽，导磁转子支架30转动时，带动中间永磁体32从一个定子槽20穿出后，进入下一个定子槽20。中间永磁体32的侧壁与定子槽20的侧壁相距预设的距离，以避免中间永磁体32随着导磁转子支架30转动时碰撞到定子槽20的侧壁。预设的距离是指在旋转过程中中间永磁体32与中间定子组件200的中间定子铁芯21重合时产生足够小的气隙，使得中间永磁体32与中间定子铁芯21形成短磁路，中间永磁体32与中间定子铁芯21错开时气隙足够大，使得中间永磁体32与中间定子铁芯21不能形成磁场回路， 中间永磁体32与中间定子组件200之间没有吸力，以实现混合磁通复合结构盘式电机1000的持续旋转。The intermediate permanent magnet 32 is placed in the stator slot 20 of the intermediate stator assembly 200. Specifically, the stator slot 20 of the intermediate stator assembly 200 is a through slot. When the magnetic rotor support 30 rotates, the intermediate permanent magnet 32 is driven to pass through a stator slot 20. After exiting, enter the next stator slot 20. The side wall of the middle permanent magnet 32 is separated from the side wall of the stator slot 20 by a preset distance, so as to avoid the middle permanent magnet 32 from colliding with the side wall of the stator slot 20 when the magnetically permeable rotor support 30 rotates. The preset distance means that when the middle permanent magnet 32 overlaps with the middle stator core 21 of the middle stator assembly 200 during the rotation, a sufficiently small air gap is generated, so that the middle permanent magnet 32 and the middle stator core 21 form a short magnetic circuit. When the middle permanent magnet 32 and the middle stator core 21 are staggered, the air gap is large enough so that the middle permanent magnet 32 and the middle stator core 21 cannot form a magnetic field loop, and there is no attraction between the middle permanent magnet 32 and the middle stator assembly 200 to achieve mixing Continuous rotation of the disk motor 1000 with a magnetic flux composite structure.
本发明中，前定子组件100与前端面永磁体31间及中间永磁体32与中间定子组件200间分别形成闭合的磁场回路，相对于现有技术中盘式电机仅形成1个磁场回路，本发明2个磁场回路提高了能量转换效率。此外，中间永磁体32和前端面永磁体31共用1个导磁转子支架30，提高了能量转换能力与盘式电机的体积重量比值。In the present invention, a closed magnetic field loop is formed between the front stator assembly 100 and the front permanent magnet 31 and between the middle permanent magnet 32 and the middle stator assembly 200, respectively. Compared with the disc motor in the prior art, only one magnetic field loop is formed. Invented two magnetic field circuits to improve energy conversion efficiency. In addition, the middle permanent magnet 32 and the front-end permanent magnet 31 share a magnetic rotor support 30, which improves the energy conversion capacity and the volume-to-weight ratio of the disk motor.
