如图1和图2所示，在一个实施例中，永磁直线电机包括：滑动本体100、磁生机构200、磁轭件300与磁性件400，磁性件400间隔设置在磁轭件上，磁轭件装设在滑动本体100中，磁生机构200与磁性件400磁性配合并用于驱动滑动本体100自身进行动作，磁性件400朝向磁生机构200的端部为弧面，且磁性件400朝向磁生机构200的端部的弧凸面朝向磁生机构200。As shown in FIG. 1 and FIG. 2 , in one embodiment, the permanent magnet linear motor includes: a sliding body 100 , a magnetic generating mechanism 200 , a yoke member 300 and a magnetic member 400 , and the magnetic member 400 is arranged on the yoke member at intervals, The yoke is installed in the sliding body 100 , the magnetic generating mechanism 200 is magnetically matched with the magnetic component 400 and is used to drive the sliding body 100 to move itself. The end of the magnetic component 400 facing the magnetic generating mechanism 200 is an arc surface, and the magnetic component 400 The arc convex surface toward the end of the magnetic generation mechanism 200 faces the magnetic generation mechanism 200 .
上述直线电机在使用时，通过磁生机构200与磁性件400磁性配合，从而实现滑动本体100自身进行动作。即磁生机构200在通电情况下会产生磁场，此时磁性件400会对磁场的磁感线进行切割，从而产生了用于驱动滑动本体100自身进行动作的推力。在实现磁生机构200与磁性件400磁性配合时，可以将磁生机构200装设在滑动本体100的动作部（指滑动本体100进行动作的部位）上，将磁性件400装设在滑动本体100的基面（指滑动本体100上与动作部位相对应的基面）上。或者将磁生机构200装设在滑动本体100的基面上，将磁性件400装设在滑动本体100的动作部上。进一步地，将磁性件400装设在磁轭件300上，此时磁轭件300能够避免磁性件400出现漏磁现象，即磁轭件300能够保证磁性件400在磁生机构200所形成的特定磁场下进行磁性配合，从而能够产生稳定的推力。同时，将磁性件400朝向磁生机构200的端部设计为弧面，从而可以有效抑制永磁直线电机在运行时所产生的齿槽力，即可以降低运行时的推理波动。因此，上述永磁直线电机能够有效降低运行时的推力波动。When the above-mentioned linear motor is in use, the magnetic generating mechanism 200 is magnetically matched with the magnetic member 400 , so that the sliding body 100 can operate by itself. That is, when the magnetic generating mechanism 200 is energized, a magnetic field will be generated, and at this time, the magnetic element 400 will cut the magnetic field lines of the magnetic field, thereby generating a thrust for driving the sliding body 100 itself to operate. When the magnetic coupling between the magnetic generating mechanism 200 and the magnetic member 400 is realized, the magnetic generating mechanism 200 can be installed on the action part of the sliding body 100 (referring to the part where the sliding body 100 operates), and the magnetic member 400 can be installed on the sliding body On the base surface of the sliding body 100 (referring to the base surface corresponding to the action part on the sliding body 100 ). Alternatively, the magnetic generating mechanism 200 is installed on the base surface of the sliding body 100 , and the magnetic element 400 is installed on the action part of the sliding body 100 . Further, the magnetic member 400 is installed on the magnetic yoke member 300 . At this time, the magnetic yoke member 300 can avoid the magnetic leakage phenomenon of the magnetic member 400 . The magnetic mating is performed under a specific magnetic field, so that a stable thrust can be generated. At the same time, the end of the magnetic member 400 facing the magnetic generating mechanism 200 is designed as an arc surface, so that the cogging force generated by the permanent magnet linear motor during operation can be effectively suppressed, that is, the reasoning fluctuation during operation can be reduced. Therefore, the above permanent magnet linear motor can effectively reduce the thrust fluctuation during operation.
在一个实施例中，磁生机构200指在通电情况下可以产生磁场。例如：铁芯与的绕组卷设配合。磁性件400可以为磁钢或磁铁。进一步地，磁性件400在滑动本体100内部的安装厚度相一致。可以利用仿真方法（指运用各种模型和技术对实际问题进行建模，并通过试验已解决相应的实际问题）对磁性件400的弧面进行优化，从而使得磁生机构200与磁性件400磁性配合时所形成的磁场波形更趋于正弦波，即更有助于永磁直线电机在运行时，降低永磁直线电机的推力波动。In one embodiment, the magnetic generating mechanism 200 can generate a magnetic field under the condition of electrification. For example: the iron core is matched with the winding winding. The magnetic member 400 may be a magnetic steel or a magnet. Further, the installation thickness of the magnetic member 400 inside the sliding body 100 is the same. The arc surface of the magnetic member 400 can be optimized by using the simulation method (referring to using various models and technologies to model the actual problems, and to solve the corresponding practical problems through experiments), so that the magnetic generating mechanism 200 and the magnetic member 400 are magnetically connected. The magnetic field waveform formed during cooperation is more sine wave, which is more helpful to reduce the thrust fluctuation of the permanent magnet linear motor when the permanent magnet linear motor is running.
在一个实施例中，磁性件400弧面的弧凸处位于磁性件400的轴线上，从而使得磁性件400在经过磁生机构200的磁场时所产生的推力更加均匀。进一步地，当磁生机构200、磁轭件300与磁性件400均装设在滑动本体100内部后，在滑动本体100进行自身动作的过程中，磁性件400均能够与磁生机构200进行磁性配合。同时，在选择或加工磁性件400的弧面时，可以根据永磁直线电机的实际动作情况或者磁性件400与磁生机构200所产生的推力波动情况调整弧面的弧度，即通过磁性件400端部弧度的改变，实现了磁性件400与磁生机构200之间的间距调整。这仅仅是其中一种实施方式，例如：当需要改变磁性件400与磁生机构200之间的间距时，也可以在保证磁性件400弧面弧度不变的情况下，通过对磁性件400自身的高度进行调整，或者改变磁轭件300在滑动本体100内部的安装高度。In one embodiment, the arc convex portion of the arc surface of the magnetic member 400 is located on the axis of the magnetic member 400 , so that the thrust force generated by the magnetic member 400 when passing through the magnetic field of the magnetic generating mechanism 200 is more uniform. Further, after the magnetic generating mechanism 200 , the yoke member 300 and the magnetic member 400 are all installed inside the sliding body 100 , during the process of the sliding body 100 performing its own action, the magnetic member 400 can be magnetically connected with the magnetic generating mechanism 200 . Cooperate. At the same time, when selecting or processing the arc surface of the magnetic member 400 , the arc of the arc surface can be adjusted according to the actual operation of the permanent magnet linear motor or the thrust fluctuation generated by the magnetic member 400 and the magnetic generating mechanism 200 , that is, through the magnetic member 400 . The change of the radian of the end portion realizes the adjustment of the distance between the magnetic member 400 and the magnetic generating mechanism 200 . This is just one of the implementations. For example, when the distance between the magnetic member 400 and the magnetic generating mechanism 200 needs to be changed, the magnetic member 400 itself can also be adjusted under the condition that the arc of the magnetic member 400 remains unchanged. Adjust the height of the yoke member 300 or change the installation height of the yoke member 300 inside the sliding body 100 .

The distance between the magnetic elements 400 can ensure that after the magnetic element 400 is installed on the sliding seat 120 or the base 110, the magnetic element 400 can effectively cut the magnetic field of the magnetic generating mechanism 200 (in addition, this is only one of the embodiments, it can also be According to the range of the magnetic field that the magnetic generating mechanism 200 can generate when energized, the installation thickness of the magnetic member 400 on the sliding seat 120 or the base 110 is determined.) Further, when installing the magnetic generating mechanism 200 and the magnetic member 400 At the same time, the installation positions of the magnetic generating mechanism 200 and the magnetic element 400 on the sliding body 100 can be flexibly selected according to actual needs.

Specifically, the magnetic base block 410 is a square magnetic steel or a rectangular magnetic steel. In this embodiment, the magnetic base block 410 is a square magnetic steel, and the arc-surface magnetic conductor 420 is a soft magnetic body, that is, the soft magnetic body is easier to process than the magnetic steel, and the use cost of the soft magnetic body is lower. In addition, the magnetic induction intensity of the magnetic member 400 can be effectively improved by the arc-surface magnet conductor 420 , and the magnetic circuit reluctance generated by the arc-surface magnet conductor 420 is smaller. Further, according to installation requirements, in order to avoid fluctuations in the thrust generated between the magnetic generating mechanism 200 and the magnetic member 400, the magnetic member 400 needs to satisfy the installation height inside the sliding body 100 to be consistent. Therefore, the yoke member 300 can Provide a flat mounting surface for the magnetic element 400 . In addition, the installation of the magnetic member 400 on the magnetic yoke member 300 may be completed before the magnetic yoke member 300 is installed in the sliding body 100 .
