I made a step-up rotary phase converter with no mathematics at all. 240V in between star-point and one leg with a cap to another leg and a small single phase motor on a belt drive to start it spinning. Output was 440V 3-phase. It might have worked better with some maths, as I am not sure that the cap was anything like the right size (the first cap size I tried was giving 1000V between 2 windings, which caused some worrying sizzling noises. ) But a VFD is just so much more convenient. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
