99.5 % efficiency electric motor sets record in 2017

Correction, that;'s
               99.05 % efficiency electric motor sets record in 2017

https://www.abb-conversations.com/2017/07/abb-motor-sets-world-record-in-energy-efficiency/

I'm not sure, but I think maybe that    > 50% efficiency    is possible only when some
amount of back EMF is constructively utilized. 

Of course most of us are aware that every motor is 100% efficient when we take into account all outputs ( useful or otherwise ).
