Lol, yeah I maybe got a little "wordy" when "bad solder joint" would have sufficed. :)

I doubt the joints were that bad that they simply fell off. I suppose it is possible if the joints were VERY cold and did not bond to the existing solder.

When you resolder them, I would use solder containing silver for a lower resistance connection, and make sure you get the existing solder hot enough to bond well. That may be difficult since the motor acts like a large heatsink. I have a 250W iron that I use for large jobs like that (and things like soldering 2GA wires together :)).
