Could mild rusty bearing initiate an ESC error?

[cedarphoenix]

My phantom pro gave an ESC error out of the blue Could mild rusty bearing initiate an ESC error? When spun by hand motor feels super slightly harder than others to spin.

Any input would be appreciated.

Have you taken it for a swim or used it in damp locations a lot? That doesn't seem right. Is the outer corroded ring the bearing or the sleeve it fits into? Hard to tell from the picture. What can be seem doesn't indicate any real issues and the windings look clean but if it has drag it may need replacement. Can the motor be disassembled by the user? If so tear it down and see what the insides look like.

It shouldn't. While it's not best for the bearing, they should be able to withstand some water. However, if the motor doesn't turn well, both that and the corrosion could be an indication something is wrong. If one motor is hotter than the others after a run, that's also an indication.
