Extending the frame so that the dropout can't twist
I have a rear hub motor conversion on 26 inch frame and the motor twisted the dropout off. I welded a new dropout on but there is no clearance for the axle to bolt on (the bolt can't be turned far in enough so that it holds the axle) so now I'm stick at either having the axle able to twist or able to fall out. What can you do in this case, fabricate a part that both holds the axle to the frame and also prevents it from turning? I'm worried it won't be strong enough if it's welded

I would scrap the project. If the hub already destroyed the frame that is a good sign that bike was not meant to be an e-bike. I don't know your welding abilities and certainly don't know anything about the frame or really anything about your situation aside from the tiny little bits you gave us but I would certainly say yeah probably not a good thing to pursue. If you are dedicated to making this thing work have someone make a frame that will hold up better. Most bikes that aren't e-bikes aren't designed to handle the loads from an e-bike conversion and problems like this can occur. If you have a really heavy duty frame maybe less likely but it happens. Some people do have good luck but I have seen enough that haven't.

It's not clear what your problem involves. Seems to me that if you can weld, you can build anything/
This is a long discussion of home made torque arms, but some of the pwople have welded up plates to clamp their motors. You might get some ides looking thru some of their posts, Go back to page 1 and start at the beginning.

If you are trying to use the dropout as a torque arm, that's unlikely to work. Paragon machine works makes some dropouts for Rohloff hubs that are made to work as torque arms, but those are $$
