Induction drives are not safe enough.
This is a design using a worm drive.
If you have exprience with worm drives you know their self breaking properties make this very safe. In addition the designs I saw years back had emergency breaking systems similar to normal elevators.

I haven't got an advice on what to buy. I do have an advice on what not to buy.
Don't trust a Trust
I have one. It is too slow. If I use it as an UPS and pull the wall plug the computer first shuts down due to power loss and then the UPS comes up and I can immediately restart my PC without putting the plug back in the wall.
It drops the power long enough to kill the PC. How can they not have detected that during testing?
It is useful for some other use cases, but not as an UPS. Just as an easy 240V power supply.
