What is the difference between a UST1152 motor and a EUST1152 motor?
Bob F on Mar 13, 2016
BEST ANSWER: There's no difference other than the label that is used. These are manufactured by US motors but may say either AO Smith or EMERSON Depending on the part number. It's basically for marketing and territory's for the manufacturer for brick and motar stores. For us, since we're an internet company and we're global, territory doesn't matter to us so we post both part numbers.

Pool Motor.
The pool motor is running really nice and is quieter than the one I had before. So far I’m very happy with it. Delivery was good and in a timely manner, faster then I expected as a matter of fact. So over all it was great 3xperience getting this motor from pool supply unlimited.

Century motor not Emerson/USMotor
I expressly searched to find a non Chinese motor. The description said USMotor (made in Mexico0 is why I ordered this one. Delivered was a Century made in China. It's working as it should, but I'm not pleased. The vendor failed to respond to my inquiry.
