Before starting the full-automatic stubble cooler, we should check the machine's electrical performance before starting the equipment. During the inspection, the blower should be used to clean the dust and other dirt and sundries in the motor at the same time, and to measure whether the wiring is qualified. If mechanical damage or spark burns are found in the motor, the necessary disposal work should be stopped immediately.

　　电机运用前的检查办法

　　Inspection method before motor operation

　　1、用紧缩空气或手动吹风机吹净电动机内部灰尘、电刷粉末等，肃清污垢杂物。

　　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，应停止烘干处置，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 less than 0.5M, the drying should be stopped and the wiring removed should be restored after qualified measurement.

　　3、检查凉茬机换向器的外表能否光亮，如发现有机械损伤或火花灼痕应停止必要的处置。

　　3. Check whether the exterior of the commutator of the stubble cooler is bright or not. If mechanical damage or spark burns are found, the necessary disposal should be stopped.

　　4、检查电刷能否严重损坏，刷架的压力能否恰当，刷架的位置能否位于标志的位置。

　　4. Check whether the brush can be seriously damaged, whether the pressure of the brush holder is appropriate, and whether the position of the brush holder can be located in the position of the sign.

　　5、依据凉茬机电动机铭牌检查直流电动机各绕组之间的接线方式能否正确，电动机额定电压与电源电压能否相符，电动机的起动设备能否契合请求，能否完好无损。

　　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 supply voltage, whether the starting equipment of the motor meets the request, and whether it is intact or not.
