Huanyang VFD and spindle problem

[BriceO]

Hi everyone,

Good news! After replacing two diodes, one resistance and two IGBT, the VFD works perfectly. I hope this will last...

Thanks for your help!! Very happy to see it work again!

Hi,
Thanks, I use this one: kdg15n120h for 2 X US4.5/pcs by HitMart Chinese (Aliexpress). But you can certainly use different one. Check the message of Jonathan to choose an IGBT.
If you have any questions don't hesitate to ask.

Thanks BriceO! I already read (carefully) all this thread, including Jonathan hints. On Aliexpress this item has disappeared and I hoped you, following Jonathan's hints , had choose an equivalence between tens of approximately equivalent items around-the-world.
Luckily, yesterday evening, hovering the Internet and seeking kdg15n120h, I might "stepped on a swarm" and this morning I got around 10 offers for this item, under 1$/pcs.
Extraordinary people these Chinese...

For those who will be in a similar situation it's good to know the locationa of that "swarm": http://www.seekic.com/

Thank you again
