Title (EN) UNIT OF ROTATABLE MAGNETIC HEADS
(FR) UNITE A TETES MAGNETIQUES ROTATIVES
Abstract: front page image
(EN)A unit of rotatable magnetic heads comprises magnetic heads rotatingly mounted. One of the magnetic heads is electrically connected with a toroidal winding (27) and the other with the winding (29) of an annular core (19) of the rotor (16) of a contactless current collector (15). Close to the rotor (16) of the contactless current collector (15) is placed its stator (18) provided with an annular core (20) having a toroidal (28) and a concentrical (30) winding. The toroidal windings (27 and 28) of the cores (19 and 20) of the rotor (16) and stator (18) are magnetically interconnected through a closed three-dimensional coupling loop, whereas their concentrical windings (29 and 30) are situated on the butt-end surfaces (23 and 24) of the rotor (16) and stator (18) magnetically interconnected and facing each other.
(FR)Une unite de tetes magnetiques rotatives comprend des tetes magnetiques montees en rotation. Une des tetes magnetiques est connectee electriquement a un enroulement toroidal (27) et l"autre est connectee a l"enroulement (29) d"un noyau annulaire (19) du rotor ( 16) d"un collecteur de courant sans contact (15). A proximite du rotor (16) du collecteur de courant sans contact (15) se trouvent son stator (18) pourvu d"un noyau annulaire (20) ayant un enroulement toroidal (28) et un enroulement concentrique (30). Les enroulements toroidaux (27 et 28) des noyaux (19 et 20) du rotor (16) et du stator (18) sont interconnectes magnetiquement par l"intermediaire d"une boucle de couplage fermee tridimensionnelle, tandis que leurs enroulements concentriques (29 et 30) sont situes sur les surfaces en appui (23 et 24) du rotor (16) et du stator (18) interconnectees magnetiquement et en vis-a-vis.
