Re: [CAD_CAM_EDM_DRO] Re: 2 toroidal transformers mounted atop one another?

Thanks for the responses on this everyone. I think what i'll do is stack them with a few inches of space in between. Bill mentioned arranging them in a "T" formation, which is probably best however, that will take up considerable room in the enclosure. If I stack them with a 2 inch high spacer made of UHMW polyethelene and machine air passages in that to aid cooling, I think it will be alright. I'll check the voltage and monitor the heating to see if its having any effect and let everyone know what I observe.

Hi, in radio work, we stack several cores together with a few thousands of
an inch spacer then wind them as one, so i dont think stacking one on top of
another is a great idea. the reason for stacking is to raise the power level
the inductor can handle.
