Are there any designs for homebrew motor inverters about? - I have had a scout round the internet without much luck. From what I can tell (electronically speaking) they don't actually seem that complicated.

Nexus do a range of books and two in particular are on electric motors, one of the books has a section onhome built inverters.

A converter is reasonably easy, but an inverter has a lot of power electronics, and in practice overload protection, and other features.
With the heat sinks the actual physical design is quite important.
What are you after specification wise... I have a dead inverter for spares or repair...

I'd be tempted to get three old UPSes with duff batteries, remove the drivers and run them from a micro with appropriately phased PWM outputs.

Get some new batteries and you can continue to make swarf during power cuts.
