2. 检查电机自己：如果电源和电路正常 ，可能是电机自己泛起故障� ？梢酝ü韵掳旆ń屑觳椋�
2. Check the motor itself: If the power supply and circuit are normal, it may be a malfunction of the motor itself. The following steps can be used for inspection:
a. 检查电机是否正常运转：将电机直接连接到电源上 ，视察电机是否能够正常转动。如果不可转动 ，可能是电机内部损坏 ，需要更换电机。
a. Check if the motor is running properly: Connect the motor directly to the power supply and observe if the motor can rotate normally. If it cannot rotate, it may be due to internal damage to the motor, which needs to be replaced.
b. 检查电机绕组和碳刷：拆开电机外壳 ，检查电机绕组是否有断裂或烧坏的情况。同时检查电机的碳刷是否磨损严重 ，需要更换。
b. Check the motor winding and carbon brush: Remove the motor casing and check if the motor winding is broken or burnt out. At the same time, check if the carbon brush of the motor is severely worn and needs to be replaced.
3. 检查控制器和开关：如果电机自己正常 ，可能是控制器或开关故障导致电机不可正常事情� ？梢酝ü韵掳旆ń屑觳椋�
3. Check the controller and switch: If the motor itself is normal, it may be due to a malfunction in the controller or switch that prevents the motor from working properly. The following steps can be used for inspection:
a. 检查控制器是否事情正常：使用万用表或电压表检查控制器输入输出端口的电压是否正常。如果没有电压输出或输入不稳定 ，可能是控制器故障 ，需要更换。
a. Check if the controller is working properly: Use a multimeter or voltmeter to check if the voltage at the input and output ports of the controller is normal. If there is no voltage output or unstable input, it may be a controller malfunction that needs to be replaced.
b. 检查开关是否正常：检查门的开关是否有松动或损坏情况� ？梢允褂猛蛴帽斫械纪ú馐� ，确� ？卣Ｊ虑�。
b. Check if the switch is normal: Check if the door switch is loose or damaged. A multimeter can be used for conductivity testing to ensure that the switch is working properly.
