It can be seen as an evolution of a traditional rotating motor that is split along its radial direction and then flattened. It is currently mainly used in automatic control systems. In order to ensure that the entire control system has a high level of positioning accuracy, high sensitivity, good follow-up and reliability, the linear motor must have correspondingly high accuracy; on the other hand, the size of the linear motor indirectly and directly determines the entire control system. Whether the system structure can be miniaturized and lightweight. For specific linear motors, achieving high precision and miniaturization while ensuring certain working performance requires providing good heat dissipation conditions.
现有技术的双动子直线电机包括并排设置的两个动子绕组，两个动子绕组之间留有缝隙。直线电机热量主要来自于动子绕组工作时产生的欧姆热。基于直线电机动子结构，其产生的热量需从两个动子绕组顶部向下传递至底部，再通过绝缘层传至动子底座，最后底座将热量传递至工作台实现散热。但该散热路径热阻较大、散热效率很低，电机长期运行易热量堆积，甚至出现“烧机”现象。同时，电机内部温度较高时，其绝缘寿命相应下降、金属部件的强度、硬度等其他力学性能也降低，严重影响电机的运行寿命和安全性。此外，传递至工作台的热量易使其发生热变形，直接影响系统的定位精度。The existing double-motor linear motor includes two mover windings arranged side by side, with a gap between the two mover windings. The heat of linear motors mainly comes from the ohmic heat generated when the mover winding is working. Based on the linear motor movable structure, the heat generated needs to be transferred downward from the top of the two mover windings to the bottom, and then to the mover base through the insulation layer. Finally, the base transfers the heat to the workbench for heat dissipation. However, the thermal resistance of this heat dissipation path is large and the heat dissipation efficiency is very low. The motor is prone to heat accumulation during long-term operation, and even "burn-in" phenomenon occurs. At the same time, when the internal temperature of the motor is high, its insulation life will decrease accordingly, and the strength, hardness and other mechanical properties of metal parts will also decrease, seriously affecting the operating life and safety of the motor. In addition, the heat transferred to the workbench can easily cause thermal deformation, which directly affects the positioning accuracy of the system.
因此，为保证直线电机高效率运行安全可靠，实现其高精度化和轻量化发展，必须开发出具有高效散热性能的直线电机和高效散热方法。为实现这一目标，本专利提出了一种基于均热板散热的直线电机和直线电机的散热方法。 Therefore, in order to ensure the safe and reliable operation of linear motors with high efficiency and achieve their high-precision and lightweight development, it is necessary to develop linear motors with efficient heat dissipation performance and efficient heat dissipation methods. To achieve this goal, this patent proposes a linear motor and a heat dissipation method for linear motors based on vapor chamber heat dissipation.

底座3设有凹槽，两个动子绕组并排嵌入于凹槽内。两个动子绕组之间嵌设有均热板，均热板两侧面分别紧密贴合于两个动子绕组，均热板下端抵接于 底座3上端，使用耐高温胶带将两个动子绕组和均热板固定在一起。The base 3 is provided with a groove, and the two mover windings are embedded side by side in the groove. A vapor chamber is embedded between the two mover windings. The two sides of the vapor chamber are closely attached to the two mover windings. The lower end of the vapor chamber is in contact with the two mover windings. At the upper end of base 3, use high temperature resistant tape to fix the two mover windings and the vapor chamber together.
采用铝型材挤压的方式加工底座3，底座3上设有与两个动子绕组和均热板底部配合的平面及用于液冷的液冷槽道31。The base 3 is processed by extruding aluminum profiles. The base 3 is provided with a plane matching the two mover windings and the bottom of the vapor chamber and a liquid cooling channel 31 for liquid cooling.
本实施例中，均热板为直立段11。直立段11均热板针对不同尺寸的直线电机动子进行定制化设计与制造。In this embodiment, the vapor chamber is an upright section 11. The upright section 11 vapor chamber is customized and manufactured for linear motor motors of different sizes.

The middle section 21 is in close contact with the vapor chamber, and the protruding section 22 at one end is embedded in the groove of the base 3 . The base 3 not only functions to fix the mover winding, but also contacts the protruding section 22 of the mover winding to achieve a heat dissipation effect.
本实施例中，均热板的宽度和高度均与动子绕组相同，使得均热板与两个动子绕组之间具有较大的导热面积。In this embodiment, the width and height of the vapor chamber are the same as those of the mover windings, so that there is a large heat conduction area between the vapor chamber and the two mover windings.

传统的直线电机产生的热量需从绕组顶部向下传递至底部，再通过绝缘层传至动子底座3，最后底座3将热量传递至工作台实现散热。但该散热路径热阻较大、散热效率很低，电机长期运行时易出现热量堆积。The heat generated by a traditional linear motor needs to be transferred downward from the top of the winding to the bottom, and then to the mover base 3 through the insulation layer. Finally, the base 3 transfers the heat to the workbench for heat dissipation. However, the thermal resistance of this heat dissipation path is large and the heat dissipation efficiency is very low. Heat accumulation is prone to occur when the motor runs for a long time.
相较于传统的直线电机，本发明的直线电机散热路径热阻极小，散热效率高，电机即使长期运行也不容易产生热量堆积，能够维持金属部件的强度、硬 度等其他力学性能，延长绝缘和电机的使用寿命，提升了安全性，传递至工作台的热量较少，不易使其发生热变形而影响系统的定位精度。Compared with traditional linear motors, the heat dissipation path of the linear motor of the present invention has extremely small thermal resistance and high heat dissipation efficiency. Even if the motor runs for a long time, it is not prone to heat accumulation and can maintain the strength and hardness of metal parts. It also extends the service life of the insulation and motor, improves safety, and transfers less heat to the workbench, making it less likely to cause thermal deformation and affect the positioning accuracy of the system.
底座3的液冷槽道31可以通入液冷介质，进一步加强散热效果。The liquid cooling channel 31 of the base 3 can pass into the liquid cooling medium to further enhance the heat dissipation effect.
实施例2Example 2
如图3、图4所示，本实施例与实施例1的不同之处在于，均热板包括互相连接的直立段11和横向段12，直立段11高度与动子绕组相同，直立段11两侧面分别抵接于两个动子绕组的中间段21，横向段12一端连接于直立段11下端，横向段12嵌入于动子绕组的突出段22与底座3之间，即横向段12上下两端分别抵接于任一动子绕组和底座3。As shown in Figures 3 and 4, the difference between this embodiment and Embodiment 1 is that the vapor chamber includes an upright section 11 and a transverse section 12 that are connected to each other. The height of the upright section 11 is the same as that of the mover winding. The two sides are respectively in contact with the middle section 21 of the two mover windings. One end of the transverse section 12 is connected to the lower end of the upright section 11. The transverse section 12 is embedded between the protruding section 22 of the mover winding and the base 3, that is, the upper and lower sections of the transverse section 12 Both ends are respectively in contact with any mover winding and the base 3.
由于均热板直立段11与底座3的接触面积较小，难以将动子绕组产生的欧姆热快速传递到底座3，导致均热板的高效导热性能无法得到更有效利用。本实施例中，均热板在动子绕组的突出段22与底座3之间增设横向段12后，均热板与动子绕组以及与底座3的接触面积同时大大增加，不仅提升了动子绕组向均热板传热的效率，而且还提升了均热板向底座3传热的效率，散热效果更好。Since the contact area between the upright section 11 of the vapor chamber and the base 3 is small, it is difficult to quickly transfer the ohmic heat generated by the mover winding to the base 3, resulting in the efficient thermal conductivity of the vapor chamber not being more effectively utilized. In this embodiment, after the vapor chamber adds a transverse section 12 between the protruding section 22 of the mover winding and the base 3, the contact area between the vapor chamber and the mover winding and the base 3 is greatly increased, which not only improves the performance of the mover. The efficiency of heat transfer from the winding to the vapor chamber is improved, and the efficiency of heat transfer from the vapor chamber to the base 3 is also improved, resulting in better heat dissipation effect.
采用热压法将均热板弯折，均热板直立段11和横向段12的纵截面为L形。The hot pressing method is used to bend the vapor chamber, and the vertical section 11 and the transverse section 12 of the vapor chamber have an L-shaped longitudinal section.
实施例3Example 3
如图5、图6所示，本实施例与实施例2的不同之处在于，两个动子绕组之间的均热板数量为两个，两个均热板并排布置形成双L形，两个均热板的直立段11互相抵接，两个均热板的横向段12背向布置且分别嵌入于动子绕组和底座3之间。As shown in Figures 5 and 6, the difference between this embodiment and Embodiment 2 is that the number of vapor chambers between the two mover windings is two, and the two vapor chambers are arranged side by side to form a double L shape. The upright sections 11 of the two vapor chambers abut each other, and the transverse sections 12 of the two vapor chambers are arranged back-to-back and embedded between the mover winding and the base 3 respectively.
由于均热板的厚度极小，本实施例采用两个L形均热板背向嵌入于两个动子绕组之间，不会对直线电机造成结构上的影响，使均热板的高效导热性能得到更充分的发挥，大大提升了直线电机的散热效果。Since the thickness of the vapor chamber is extremely small, in this embodiment, two L-shaped vapor chambers are embedded back-to-back between the two mover windings, which will not have a structural impact on the linear motor and ensure efficient heat conduction of the vapor chamber. The performance is fully utilized and the heat dissipation effect of the linear motor is greatly improved.
