Damn. Kinda what I suspected for the cost but even so...🤨 Thanks for the Heads Up. Good for battery outage or transporting but little else. I'll go turn mine off and look for the tiniest real pump I can find!
I have one too, and it failed after two weeks. when i inspected the motor the copper shim over the base shaft had crumbled away. now i'm trying to find a replacement motor i can use to keep the dream alive
I don't think that kind of motor is made for long continuous operation, there is no material in the brushes to support it, and the brushes contact area are quite small, check the size of the brushes used with appliances, drills, etc For continuous operation it may need a "brushless" motor.
While these motors definitely don't have the same service life as universal motors in vacuum cleaners, tools, and kitchen appliances for example, they also have much less current passing through them, which has a large effect on brush material loss. Brushed motors of this size (and even smaller) are used in things like CD/DVD drives, tape drives, belt driven turntables, and they are expected to have thousands of hours of service life in those applications.

Big anoucement. That motor is serviceable.You can buy rear mount of the motor to replace it
I wouldn't be surprised if they put a repurposed motor or brushes in there that they had still in a corner of the factory.
So just bad brush quality then? Or any chance the commutator wasn't deburred.
Never seen anything that bad.
That's a good theory with burrs on the commutator. That would chew them up pretty fast.
