I have a feeling that that might not have a large enough current capacity, though. I just found my proto circuit, and it has a transformer on it, and I probably did that for a reason. > Oh yes, I really would like to do that. > Unfortunately I do not have much of a choice to get those motors > running.

You might not get the chance to learn from mistakes. Re your question about a 1:1 transformer, I think you probably want a 2:1 anyway, as rectified mains will give you >300V and your motors are specced for 160V. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
