  直流电机是将直流电转化为机械能(直流电机)或将机械能转化为直流电能(直流电发生器)的旋转电机。它是一种能实现直流电能与机械能相互转换的电机。在使用操作时要注意操作方法和步骤,如操作不当,影响使用效果,在应用中要注意哪些基本点?
  DC motor is a kind of rotating motor which converts DC into mechanical energy (DC motor) or mechanical energy into DC energy (DC generator). It is a kind of motor which can realize the mutual conversion of DC power and mechanical energy. Pay attention to the operation methods and steps when using the operation. For example, improper operation will affect the use effect. What basic points should be paid attention to in the application?
  1. 在拆卸前,先检查无刷直流电机的外观完整性,然后用压缩空气将无刷直流电机表面的灰尘吹掉,清除表面污垢。
  1. Before disassembly, check the appearance integrity of the BLDCM, and then blow off the dust on the surface of the BLDCM with compressed air to remove the surface dirt.
  2. 选择直流无刷电机分解工作场所来清洁现场环境。

  2. Select the DC brushless motor decomposition workplace to clean the site environment.
  3.熟悉无刷直流电机的结构特点和维护要求。
  3. Be familiar with the structure characteristics and maintenance requirements of BLDCM.
  4. 准备拆卸所需的专用工具和设备。
  4. Prepare special tools and equipment for disassembly.
  5. 为了进一步了解无刷直流电机运行中的缺陷,如果条件允许,可以在拆卸前进行检查和测试。因此,加载直流无刷电机进行试运行,详细检查直流无刷电机各部分的温度、声音和振动,测试电压、电流和速度。然后断开负载,分别进行空载检测试验,测量空载电流和空载损耗,并记录。
  5. In order to further understand the defects in the operation of BLDCM, if conditions permit, inspection and test can be carried out before disassembly. Therefore, load the DC brushless motor for trial operation, check the temperature, sound and vibration of each part of the DC brushless motor in detail, and test the voltage, current and speed. Then disconnect the load, carry out no-load detection test, measure no-load current and no-load loss, and record.
  6. 切断电源,拆除直流无刷电机外部接线并记录。
  6. Cut off the power supply, remove the external wiring of DC brushless motor and record.
  7. 选择万用表测试直流无刷电机的绝缘电阻。为了比较上次大修测量的绝缘电阻值,判断直流无刷电机的绝缘变化趋势和绝缘状态,需要将不同温度下测量的绝缘电阻值换算为相同温度,一般为75℃。
  7. Select a multimeter to test the insulation resistance of the DC brushless motor. In order to compare the insulation resistance measured in the last overhaul and judge the insulation change trend and insulation state of DC BLDCM, it is necessary to convert the insulation resistance measured at different temperatures into the same temperature, generally 75 ℃.
  8. 吸收率k,当吸收率大于1.33时,说明直流无刷电机的绝缘不受湿度的影响或湿度程度不严重。为了与以前的数据进行比较,在任何温度下测量的吸收率也应该转换为相同的温度。
  8. Absorption rate k, when the absorption rate is greater than 1.33, it indicates that the insulation of DC brushless motor is not affected by humidity or the degree of humidity is not serious. In order to compare with the previous data, the absorbance measured at any temperature should also be converted to the same temperature.
  9. 检查完所有问题后,对发现的问题进行处理,重新组装,并进行检查。
  9. After all problems are checked, the problems found shall be handled, reassembled and checked.
  主要用于直流电机、电解、
  Mainly used for DC motor, electrolysis
  直流发电机是将机械能转换成直流电的机器。主要用于直流电机、电解、电镀、电炉冶炼、充电及交流发电机励磁电源。虽然在需要直流电源的情况下,也使用整流电源元件,将交流电转换成直流电,但从某些方面的性能来看,交流整流电源并不能完全替代直流发电机。
  A DC generator is a machine that converts mechanical energy into direct current. It is mainly used for DC motor, electrolysis, electroplating, furnace smelting, charging and alternator excitation power supply. Although in the case of DC power supply, rectifier power supply elements are also used to convert AC to DC, but from some aspects of performance, AC rectifier power supply can not completely replace DC generator.
