1. A system comprising on the one hand a brushless electric motor and on the other hand a complementary connection assembly, with said brushless electromagnetic motor comprising a coiled stator assembly with P electric phases and X coils per phase, with each coil being carried by a body provided with two connection slots, said connection assembly comprising a first sub-assembly formed of W tracks cut in a conductive sheet, with said tracks forming W coplanar output tracks, with W being an integer between P and P+I, with each one of said W tracks terminating in at least one end folded back perpendicularly to the plane of said tracks, with the shape of said folded back end being complementary to the shape of the connection slot, with said tracks being joined by an insulating plastic material.
