So this is a known problem for some random motors?
I have asked on the Orion forums, hopefully maybe Oscar himself can offer a solution.

As ShrekNZ says, it is because when you side-swipe the car against a barrier, or get T-boned, the armature pushes the endbell bearing out. This allows the tags on the comm to hit the tubes, and burrs them over.

The solution is to get some 1/8th id tubing - tough plastic or brass, not fuel tunbing - and put it as a spacer between the pinion boss and the can-end bearing. Now, when the armature tries to move, it is stopped by this spacer, and the tags don't hit the tubes. I allow a small gap (0.010") between the spacer and the bearing so the armature can still float in the can, but as soon as it tries to move any further, it is stopped. HTH

I asked on the Orion forums, I was told to drill/ream out the brush hoods with a 3.8mm bit. I did it, the brushes now seem to move freely up and down the hoods, so hopefully that problem is solved.
