RE: [CAD_CAM_EDM_DRO] Latching Contactor Relay Question, oT?

I run 3 phase motors on single phase 240V on a few machines. Most of the 3
phase motors I see are 440V star, I re jumper them for delta and use an
inverter (variable frequency drive) giving continuously variable speed from
<100 to >2500 RPM.

Insert smart assed comment here.
all the people I know (myself Included) go to great lenghts to run
3 phase motors on single phase. I would assume that the motors would run
fine until a load was put on them. you might want to look into rotary
phase converter as a way to power three phase motors near their full
rated output.
