brushed motor burnout

The 1st dead brushed motor happened. It manifested itself as a propeller that wouldn't turn without a lot of resistance, despite having no hair clog. The brushes must have disintegrated, leaving high friction copper. None of the other 3 motors have disintegrated, however. Those things don't last long.

Time to paint some more of the floor. Painter's drop cloth doesn't work because it's only 3' wide. A tarp would be ideal if it was black or white. The apartment is only big enough to paint a small area at a time.
