Yes.
Lathe has the VFD for the spindle, plus a 3 phase motor controlled via contactors for the turret.
Old Harrison mill with a 2hp motor is still running completely from 3 phase, as it needs the 3 phase for the power feed motor (although this machine is likely to go once I get the big mill up and running)
Plus an old tyre changer that gets used occasionally.

The Harrison mill is the one that puts the most strain on the rotary converter.

The big mill I'm still undecided on whether to make it completely 240V, or run the spindle using 400V (the motor insulation isn't rated for VFD use, so if I go VFD I need to add a filter).


I am tempted to hook up the 240-400V VFD I've got to the current idler motor, and see what happens, however I'm not entirely sure how much wiring changes I'd need to do to test things. It might be something to try once it's a bit warmer for dealing with wiring in the unheated part of the workshop. If the 4KW VFD and idler motor (I think it's a 4hp motor..) can handle starting the Harrison, then there may be some mileage in investigating this further.
