I designed some of the equipment for smart motors, but it was only for diagnosis (short trip from there to build in). You would connect an accelerometer and thermocouple to a motor and then with your phone you would connect with the service center. The tech there would have you change speeds while looking at the live results. He could then tell you if the bearings were bad, good for another month, or all is well.

A certain famous electric car company based near here was using some of the gear I designed, the last I heard.
