Powering high frequency grinders with a VFD? Also how good are HF tools?

Yes, you wouldn't enable flux vector control in an application like this. You are mimicking a fixed voltage fixed (higher) frequency supply without any attempt to optimize a specific motor's performance over its full application range.

In my case, even though I'm running it at 50Hz 415V, it still wouldn't be appropriate. The inverter doesn't know which machine tool/s I'll turn on next...

My main point was that inverter output designs have been robust enough to cope with downstream switching for quite a time. Hence the ubiquity of the 12-240V boxes you can get for cars and caravans etc.
