Hi Carter,
I wouldn't say NEMA 3 unless the motor had been certified to be NEMA 3. As you probably read in the link that I supplied, NEMA ratings include other considerations besides just intrusion protection. The chart that correlated the two ratings listed NEMA 3 as the minimum NEMA rating that would cover IP 54.
Most European companies focus of international ratings and certification, NEMA is a US rating. So while it would be nice if these companies also went through the trouble of getting US ratings, I believe that they have their hands full with a number of rating/certification requirements that US companies are not required to deal with.
But the bottom line is that while similar in some respects, an IP 54 rating does not mean the same thing as NEMA 3 rating.
Fair winds,
