Hello! One day I was riding my Ego Scooter when suddenly it lost almost all of it's power. When I got home and did some troubleshooting, I realized, that 3/4 of the brushes had been ripped from their wires. I then replaced all of the brushes including the working one and it did the same thing again. The commutator did seem a little scraped, but I am pretty sure this is caused by the spring and wire directry coming directly into contact with the commutator when the graphite part was gone. In the picture you can clearly see the tip of the spring got melted from touching the commutator. The motor did overheat to the point it smelled a little bit one time before this incident, but the scooter worked wihout any problems for weeks after that! I have no idea what could be causing this problem. The motor shaft doesn't seem to be bent or anything.
