Default IFMAR Brushless rules


As visible from:


Only three slot (phase) Y wound stators are permitted. No delta wound stators allowed. Only circular (round) pure copper wire permitted. No turn limit.

Does anybody know the sense of this rule ?
Since the number of winding is free ... why put this limitation ?

It is just for take out all the sensorless brushless motor already available in the market, like Hacker Lehner Faigo, etc ? or there is a technical reason ?

Basically from what I undestand, the allowed winding style is the lesser power style, keeps the motors closer to equal power outputs from similar sizes.
