As you've already spotted, the issue is that it's a single voltage motor, which precludes the use of the cheapest Chinese inverters, but there are other solutions.

The motor can likely be re-connected internally to allow delta, rather star winding, to allow for the cheaper inverters.
I believe some firms who supply inverters, such as Newton Tesla, will assist with that so long as you buy the inverter from them.

You can get static and rotary 3 phase converters, from such as Transwave, but they might be a bit over the top pricewise for a single machine. Machine Mart used to do a cheaper one.

Many UK based inverter suppliers now offer a 240v in – 415v 3 phase out inverter/VFD, though they are more expensive than the 240v in – 240v out ones, but they seem to have vanished off ebay of late. I think you need an AT3 type for the higher voltage output. Again Newton Tesla, or maybe Inverter Supermarket.

Premier Machine Tools also offer a suitable package, though I've not used them myself.

Plenty of options there, without needing to replace the motor; I'm sure others will be along soon to chip in.

Looks like it is either a Hammond or an Eagle.

Guessing it must be the Hammond – because a simple search on the forum would have provided oodles of info on the Eagle.

Go on, don’t be so secretive with the details. Which machine is it?
