Linear to unregulated PS?

[LeeWay]

I am curious about this. I have a 24vdc 6A linear regulated PS. I am running a 48vdc 7.3A unregulated PS. Can these two be parallel connected for double the amps, say about 13A? It would be easy enough to isolate the PS case ground on either of them. They would still have the common input lines though.

My problem is that I don't think I am getting enough Amps. My motors are on 203V's. 269 oz. and they just do not seem near as strong as they were on another machine. I also have several PC PS's. I have a couple 450 watt supplies. Would it be better or is it possible to use one of these with one of the other supplies.
I understand how to connect all the different supplies, but just not sure how different types of supplies will work together or if they will at all.
Any advice will certainly be helpful.
Thanks.

I would avoid attempting this at all costs.
For one thing the voltages are totally incompatible, and regulated supplies can be temperamental when paralleling in any case.
You are better off to get hold of a Toroidal transformer of the correct VA that you can modify easily if you have to by removing/adding turns for correct voltage out.

Thanks, Al. I was thinking there was a reason that I shouldn't attempt this. I know full well they weren't designed to run like that. Both supplies are complicated units as well. Neither was cheap enough to just try out.
I will look for or build a better supply and probably just Ebay these two. Both are decent for smaller motors. The other machine I used the smaller supply on was my router. Now they are on a mill and I just need bigger motors and more power. Cutting steel just requires a lot more torque and holding power for desired results.
