- hello everyone
in that video we are teaching how to repair vfd,in that video we will give full vfd repair training. We have vfd repairing lab where we will teach you how to repair vfd diy.we will teach you vfd repairing in Hindi/Urdu with complete practical, this is complete course for vfd repairing
The basic:
At first I would like you to understand, what is the main parts of a VFD.
1. The first is the bridge rectifier diodes. You see 4 diodes if your device is require one phase, or 6 diodes if it require 3 phase input.
2. In the middle you see an inductor and a capacitor for smoothing both the voltage and the current. It is called "DC - bus"
3. On the right side of the video , you can see the 3 phase IGBT bridge. The bridge contains 6 high power IGBTs.
Start the repair
At first you should not want to power up the drive, without you actually measured the power section! If you power up the inverter without you measured it and it has a short on the power section you may get a big surprise, so be careful.👹
From experience, I can define three most common fault, that VFDs have:
The most common problem comes from some people miss reading the sticker on the drive, what voltage is it require. With this move, they often kill the diode bridge and some input protection VDR (Varistor).
The second common problem is the condensators, what are the weakest component in the entire drive. The condensators life time is much shorter then any other parts in the drive, so if you repair any damaged VFD you should replace those as well.
The third problem is often come with the bad heat dissipation. If the IGBTs or the diodes get too hot, one, two, or even more go to short. This caused by the IGBT drive circuit fault, or the heat shock on the power section.
step 1 first you have to check power section with multimeter.
step2 if vfd is showing dead check charging resistor.
step3 check igbt module with multimeter.
step4 if vfd is on and give you some fault note fault and search it in vfd manual in warning and solution section

❤ sir
India se dher sara ❤ sir
Good
Good job bro I need it
Good job dear
Good job Mamo 👏
nice tracing of cct board
Thanks
Nice
bhai single phase vfd input 220 volt /output 3 phase hi kya hum output pe single phase water pump motor chla skty hi plz reply
yes but with filter
HOW WE CAN FIND SCHEMATIC DIAGRAM OF PARTICULAR VFD MODEL?? PLZ SHARE INFORMATION REGARDING IT AND I RECOMMEND TO MAKE VIDEO REGARDING FINDING SHCEMATIC DIAGRAM OF ANY MODEL OF VFD
Yes it is the first step for people like me to find the schematics and get help from it. Because its difficult to understand unseen or unknown circuits without schematics for me
sir g Mera pas 4kw ka drive he isme bar bar vdr fattraha he kya fuilty ho sakta he
