電動(dòng)卷簾門電機(jī)故障及檢測(cè)方法

來(lái)源:http://m.bankrobot.cn 日期:2022-02-17 發(fā)布人:
電壓測(cè)量法是更常用的檢修方法之一,就是通過(guò)測(cè)懷疑點(diǎn)電壓是否正常來(lái)判斷故障部位和故障原因。比如在檢修電機(jī)不轉(zhuǎn)、而儀表盤亮故障時(shí),可通過(guò)測(cè)控制器的供電電壓和輸出電壓判斷故開部位:再比如檢修電機(jī)轉(zhuǎn)速不正常故障時(shí),可通過(guò)測(cè)調(diào)速轉(zhuǎn)把輸出的控制電壓來(lái)判斷它是否正常。
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.

電阻測(cè)量法是更主要的檢修方法之。該方法就是通過(guò)測(cè)懷疑的線路、 器件的阻值是否正常,來(lái)判斷故障部位和故障原因。比如在檢修電機(jī)運(yùn)轉(zhuǎn)不正常故障時(shí),可通過(guò)測(cè)電機(jī)3個(gè)繞組的阻值,判斷它是否匝間短路或斷路,而檢修無(wú)刷電機(jī)時(shí),測(cè)它的3條傳感信號(hào)輸出線對(duì)地和5V供電之間的阻值時(shí),可判斷霍爾元件是否損壞:再比如在整車無(wú)電故障時(shí),還可測(cè)量保險(xiǎn)管、電源鎖和供電線路是否斷路,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.

在檢測(cè)線路、電源鎖等器件是否斷路時(shí),可采用萬(wàn)用表“蜂鳴”檔(有的數(shù)字萬(wàn)用表該功能附加在“二極管”檔上)進(jìn)行測(cè)量,若萬(wàn)用表發(fā)出鳴叫聲,說(shuō)明線路正常:若沒(méi)有鳴叫聲,說(shuō)明線路已斷:若有時(shí)鳴叫有時(shí)無(wú)聲,說(shuō)明線路接觸不良。
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.
分類
classification
電阻測(cè)量法有在路檢測(cè)和非在路檢測(cè)兩種。在路檢測(cè)法就是在線路上或電路板上直接檢測(cè)元件的阻值,不在路檢測(cè)就是單獨(dú)檢測(cè)該元件阻值。
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.
