SIX POLE DYNAMIC-ELECTRIC SYNCHRONOUS MACHINE WITH PERMANENT MAGNET

摘要

1. Synchronous six-pole electrodynamic machine with permanent magnets (44) comprising a rotor (18) of the flux 5 concentration type having a shaft (36) made from an amagnetic material on which rest six parallelepipedic radial permanent magnets (44) of high energy type between which the pole pieces (34) are disposed which are made from magnetic ferrosilicon metal sheet and a stator (14) comprising a carcase made from ferrosilicon magnetic metal beet in which a plurality of semi-closed notches (30) are formed defined by a stator yoke (32) which receive induced coils (28), and which defines an airgap (22) with the rotor (15), characterized in that the ratio r1 the height (h) of the cross-section of a magnet through which the induction flux flows divided by the bore diameter (d) of the airgap is between 0.281 and 0.344.
