I also seem to recall a name attached to the handheld device you're describing, but I don't remember it, even though we had one in the lab at Zenith.

Thanks. Yeah, looks like it, 'cept ours was a bit bigger and sounded like it had a mechanical interrupter driving the primary, like a Model T spark coil on steroids.

3 phase motors can be run from single phase supplies using variable frequency drives. Here's a random example from googling "3 phase vfd": https://www.ebay.co.uk/itm/144979535330?_ul=GB

Most certainly. We've installed several of these over the years where only single phase power is available. They work very well, but cost $$$
