电动卷帘门电机故障及检测要领
电压丈量法是更常用的检修要领之一，就是通过测怀疑点电压是否正常来判断故障部位和故障原因。好比在检修电机不转、而仪表盘亮故障时，可通过测控制器的供电电压和输出电压判断故開部位:再好比检修电机转速不正常故障时，可通过测调速转把输出的控制电压来判断它是否正常。
Voltage measurement method is one of the most commonly used maintenance methods, which is to judge the fault location and cause by measuring whether the voltage at the suspected point is normal. For example, when the motor does not rotate and the instrument panel is on, the fault opening position can be judged by measuring the power supply voltage and output voltage of the controller; for example, when the motor speed is abnormal, whether it is normal can be judged by measuring the control voltage output by the speed regulating handle.

电阻丈量法是更主要的检修要领之。该要领就是通过测怀疑的线路、 器件的阻值是否正常，来判断故障部位和故障原因。好比在检修电机运转不正常故障时，可通过测电机3个绕组的阻值，判断它是否匝间短路或断路，而检修无刷电机时，测它的3条传感信号输出线对地和5V供电之间的阻值时，可判断霍尔元件是否损坏:再好比在整车无电故障时，还可丈量包管管、电源锁和供电线路是否断路，控制器是否短路等。
Resistance measurement is one of the most important maintenance methods. This method is to judge the fault location and cause by measuring whether the resistance value of suspected lines and devices is normal. For example, when repairing the abnormal operation of the motor, you can judge whether it is short circuit or open circuit between turns by measuring the resistance of three windings of the motor. When repairing the brushless motor, you can judge whether the hall element is damaged by measuring the resistance between its three sensing signal output lines to the ground and 5V power supply. For example, when there is no power failure of the whole vehicle, you can also measure the fuse Whether the power lock and power supply line are open circuit, whether the controller is short circuit, etc.
在检测线路、电源锁等器件是否断路时，可接纳万用表“蜂鸣”档(有的数字万用表该功效附加在“二极管”档上)进行丈量，若万用表发出鸣叫声，说明线路正常:若没有鸣叫声，说明线路已断:若有时鸣叫有时无声，说明线路接触不良。
When detecting whether the circuit, power lock and other devices are open circuit, the "beep" gear of the multimeter can be used for measurement (the function of some digital multimeter is attached to the "diode" gear). If the multimeter emits a beep, it indicates that the circuit is normal; if there is no beep, it indicates that the circuit is disconnected; if it sometimes beeps and sometimes silent, it indicates that the circuit is in poor contact.

电阻丈量法有在路检测和非在路检测两种。在路检测法就是在线路上或电路板上直接检测元件的阻值，不在路检测就是单独检测该元件阻值。
There are two kinds of resistance measurement methods: on-line detection and off-line detection. The on-line detection method is to directly detect the resistance value of the component on the line or circuit board, and the off-line detection is to detect the resistance value of the component separately.
