A NEW APPROACH FOR ASSEMBLING PERMANENT MAGNETS ON ROTOR OF A PERMANENT MAGNET GENERATOR USING MAGNETIC BOLTS AND FLUX BARRIER

摘要

A permanent magnet generator for synchronous generator, comprising: a rotor(8) having a sleeve (1), the sleeve (1) constitutes atleast one flat surfaceconfigured thereon a plurality of tapped holes (9); a sfator (10) wound with threephase fractional slot winding (12); a plurality of magnets (4) mounted on the atleast one flat surface of the sleeve (1) by means of corresponding number of poleshoes (5) and bolts (6), characterized in that: at least one flux barrier (7) isprovided being interposed in the pole shoe (5) so as to reduce the flux leakage,and in that: the bolts (6) comprise high strength magnetic bolts.
