24 Volt DC motor from Neuton CE5.4 battery-electric lawn mower.  This is a 500W brushless motor that runs at 4300 rpm and has a quiet < 80 dB rating.  I guarantee that this works as advertised, i pulled it from a mower that was running and working perfectly (actually i turned the mower off before removing). The mower had less than 1/2 season mowing, that's why this is in such prime condition cosmetically and functionally.   Easy to replace, 4 included bolts will do the trick.  Everything in photos is included.
