Paired this up with a 5HP compressor pump from a well-known discount tool place that rhymes with 8. Had to buy the right sized pulley for the motor but you must do that with any motor. 5/8" pulley fit the motor shaft perfectly, so good quality control there. Running this off my residential single phase 240VAC service. Motor seems to run a little on the warm side, especially one rated for continuous duty, but maybe that's normal for a 5HP motor. This is my first one.
The base of the motor has many slots and holes to fit all standard motor mounting plates, which is very nice compared to some motors that just have a few holes punched in the mounting plate. Motor shaft comes with a key installed and a piece of heatshrink holding it on. The motor came very well packed with zero damage. I was worried about shipping but there's nothing to worry about. The motor comes surrounded by a thick, Styrofoam sleeve that's goes inside a sturdy cardboard shipping box. No way the motor is getting harmed with any kind of normal UPS/FEDEX style shipping.
Time will tell how long it lasts and if I have problems I'll come back and edit this review. So far, I'm very impressed.
