A recent thread here talked about the failure rates of the VFDs that come with Chinese spindles. They are cheap, but could we do better?

I just wondered if anyone had successfully used VFDs sourced elsewhere, with their Chinese spindle? I have used Siemens and Mitsubishi VFDs to drive three phase mains induction motors on my manual mill and lathes with great results, and such VFDs are readily available used on eBay for decent prices. They are well made, and well proven designs, aimed at industrial use. They also appear to support the 400Hz output frequencies that the Chinese spindles require. So if such kit could be deployed with a Chinese spindle, maybe an improved degree of reliability would result?

Keen to hear from anyone with thoughts or experiences on this!

Cheers
