You ask what sort of price for a suitable VFD - that's very much down to what you want to pay. You can get a quality VFD for - I don't know, several hundred quid. You can get a cheap one for fifty quid, that the advert caveats for low-loads only (which worries me). The usual suspect often used is a HuanYang VFD - not the best, but swamped the market with an affordable solution that many of us bought (the market is currently swamped with cheaper versions). Caution is needed with the HuanYangs as the Chinese are known to knock off their own knock-offs, and the suggestion is there are counterfeits out there. For that reason I'm not going to link any because I don't want the responsibility of pointing you at something that could be wrong.

But, to try to be helpful, the basic spec you're looking for is:-

220VAC single phase input, 50Hz
220VAC three phase output, 0-400Hz
1.5kW (higher is okay, lower is not)

Thank you Doddy
That is plane and simple to me and understand your concern about the cheap vfd .
now to start thinking about this
