Just checked a recently published motor catalog and noticed they are providing service factors for fractional single phase and efficiency percentages for 3 phase. There were no single phase pump motors @3/4 hp and 240 volt that had a current rating over 5.30 at 1.15 SF.

Rewired, can you get all the info off of the nameplate including the manufacturers name?

Now, I do know that motors are costing less money than 10 years ago due to importation.
But, I am finding excellent quality. Better laminations, coated magnet wire and higher end bearings. Mandated requirements,and efficiencies have led the motor industry to improve and meet certain standards.
