Very briefly: I ran across an unusual motor hardware config in a clothes washer, and wonder if this would be common to more applications.
The pump to eject water after a cycle, was constructed with two rather powerful ceramic magnets on the armature [ brushless ] in a wound stator, 120v ac ....... It had a really respectable torque for its size, and did not seem to be affected much by a locked-rotor, due to the pump being clogged by lint. I have seen many other lesser motors fried to a crisp in short order under those circumstances.
Anyone else ever run across these ??
