Comparing Reliability and Origins of Pool Pump Motors

Jandy Plus HP B2854 pool pump motor died again. Less than 4 yrs. -

Are all the B2854 motors with mfr. names such as Century, Centurian, Magnatek, A.O. Smith, etc. all made the same and do they all fall under the Regal Beloit corporate umbrella?

Is there a mfr. with better reliability?  Are they all made in China?  Appears they all have only a 1 yr warranty except the Pure Line motor A.O. Smith motor available from InyoPools.  How is this one different?

Thanks for shedding light on this most confusing array of pump mfrs.
