Before starting the stubble cooler, we should check whether the machine's motor is normal before starting the equipment. When checking, we should use the hair dryer to clean up the dirt and debris in the motor, and also measure whether the wiring is qualified. If we find mechanical damage or spark burning marks in the motor, we should do the necessary treatment immediately.

电机运用前的查看方法

Viewing method before motor operation

1、用压缩空气或手动吹风机吹净电动机内部尘埃、电刷粉末等，污垢杂物。

1. Use compressed air or manual blower to clean the dust and brush powder inside the motor and remove dirt and impurities.

2、撤除与电动机衔接的一切接线，用绝缘电阻表丈量绕组对机座的绝缘电阻。若小于0．5MΩ时，应进行烘干处理，丈量合格后再将撤除的接线恢复。

2. Remove all connections connected with the motor and measure the insulation resistance of the winding to the base with an insulating resistance meter. If it is less than 0.5M, it should be dried and the wiring removed will be restored after the measurement is qualified.

3、查看凉茬机换向器的外表是否光洁，如发现有机械损害或火花灼痕应进行必要的处理。

3. Check whether the exterior of the commutator of the stubble cooler is clean or not. If mechanical damage or spark burns are found, the necessary treatment should be carried out.

4、查看电刷是否严重损坏，刷架的压力是否恰当，刷架的方位是否坐落标记的方位。

4. Check whether the brush is seriously damaged, whether the pressure of the brush holder is appropriate, and whether the direction of the brush holder is in the direction of the mark.

5、根据凉茬机电动机铭牌查看直流电动机各绕组之间的接线方式是否正确，电动机额定电压与电源电压是否相符，电动机的起动设备是否符合要求，是否完好无缺。

5. According to the motor nameplate of the stubble cooler, check whether the connection mode between the windings of the DC motor is correct, whether the rated voltage of the motor is in accordance with the voltage of the power supply, whether the starting equipment of the motor meets the requirements, whether it is intact or not.
