FIELD : electric engineering, possible use in structures of rotors, operation conditions of which require protection of constant magnets from damaging influence of aggressive environments. SUBSTANCE : rotor contains glued constant magnets made of rare-earth metals, flooded with compound and hermetically protected from influence of working environment by means of welding of a clip with end disks. To simplify manufacturing technology, in the gap between constant magnets and one of end disks an additional disk is installed with axial apertures for injecting compound and lead-in bevel for facilitating press-fitting of the clip. EFFECT : due to usage of an additional disk, technological operations of compound injection into special form and of adjustment mechanical processing of compound are excluded. 1 dwg
