I am an engineer, and that's utter nonsense. Gears bed in, them starting to make noise has nothing to do with bedding in. It's poor quality materials and tolerances. No other motor has this issue. It's a gen motor. It has some issues. They will be improved.Being a retired mechanic, we like to see gears bed in, it is normal and expected. Without this, gears and bearing will always run hot due to stress. I think it is perfectly normal for a new Avinox motor to be completely quiet and once it is broken in the gears now have a slightly larger tolerance than when new, hence some play. Whether the gears are hardened steel or composite material they initially have to mesh with each other which is normal wear.
Engineers may find a way to keep them quiet as they wear but the solution can’t be something that artificially shortens the life of the gears by applying pressure to keep them from making noise when not under load.
