Designed for cost, not durability

NO RATINGS
The analogy with record-player motors is very apt. I've restored a bunch of turntables, and the motors tends to not have been designed with long life in mind. Nor are they designed to provide reasonable torque, which is something you'd think would be a requirement. Like so many other things, the prime design requirement seems to have been, make it cheap. So typically the bearings don't maintain lubrication all that well and they get gunked up pretty quickly, reducing torque, and so the motors can't turn the platter. Not as bad as your one-bearing Sears refrigerator motor, but not great design either.
