Technical Problem
[0003]中国实用新型专利公告号：CN218416100U，公开了：一种直流微电机，该直流微电机，说明书公开了，通过气缸的输出端固定连接有活动板，活动板的内侧固定连接有挡板，挡板的内侧固定连接有限位板，起到了过载保护的效果，从而可以加速空气流通进而对电机进行散热，可有效地防止因为高温损坏电机，解决了现有的直流微电机存在不具备过载保护的功能，从而当直流微电机长时间工作时会产生高温，进而容易导致高温损坏电机的问题，但是，该直流微电机只能进行简单的风冷散热，其散热效果不佳，在较为苛刻环境或炎热地区使用时，还是会出现电机高温停转的情况发生，严重时，会出现高温损坏电机的情况发生
Benefits of technology
[0019]1、该自适应负载直流微型电机驱动结构，通过将抽液散热单元与电机自身传动相连，利用第二从动转轴带动叶轮本体旋转，不需要使用外部送液驱动组件，简化了整体结构并降低了能耗，同时抽液速度可随直流微型电机的负载变化自动调整，实现了散热效率与电机负载的自适应匹配，有效提升了散热及时性和电机运行稳定性。

Abstract
The utility model relates to direct current micro motor technical field, and disclose adaptive load direct current micro motor drive structure, including direct current micro motor and speed reducer shell, and the liquid pumping heat abstracting unit of located speed reducer shell inside and radiator shell of direct current micro motor outside, the output shaft fixed mounting of direct current micro motor has main rotating shaft, the outside of main rotating shaft is installed with lower main transmission gear and upper main transmission gear from below to above in turn along the axis direction. This adaptive load direct current micro motor drive structure, through with the motor own transmission link of liquid pumping heat abstracting unit, utilize second driven shaft to drive impeller body rotation, need not to use external liquid sending drive assembly, simplified overall structure and reduced energy consumption, the speed of liquid pumping can be adjusted automatically along with the load change of direct current micro motor, realized the adaptive matching of heat dissipation efficiency and motor load, effectively promoted the heat dissipation and timeliness and motor operation stability.
