Most likely the motor bearing went bad. It's a common issue. Dirt gets into the power module then into the motor bearing. You should take some steps to prevent it from happening in the new motor.
A few things that will help
- Seal up the power module as described here: https://www.arrmaforum.com/threads/help-me-upgrade-my-senton-3s-for-sand.20322/post-297587. Another option is making a hole in the chassis that lets dirt fall out of the power module.
- Use an o-ring and washer to seal off the motor as described here: https://www.arrmaforum.com/threads/blx-motor.20999/page-2
- HPI Gearbox Spacers - Part #101291. Shim the slipper so it doesn't rub the power module and create that black dust.
- Rubber sealed motor bearings
