Abstract: front page image
(EN)Disclosed is a rotator core having an improved quality and an improved reliability thanks to prevention of core crack of the rotator core. The rotator core (10, 25) provided with a laminate of substantially cylindrical core blocks (12, 13, 26, 27, 28) and magnets (20) is characterized in that the core blocks (12, 13, 26, 27, 28) have magnet-accommodating holes (16, 17) extending in the axial direction to the core blocks (12, 13, 26, 27, 28), the magnets (20) are accommodated in the magnet-accommodating holes (16, 17) and secured with resin and that the axial position(s) of the core block boundary surface(s) (23, 30, 30a) along which the core blocks (12, 13, 26, 27, 28) are in contact with each other (one another) and the axial position(s) of the magnet boundary surface(s) (22, 31) along which the magnets (20) are in contact with each other (one another) are different.
(FR)La présente invention concerne un cœur de rotateur présentant une qualité améliorée et une fiabilité améliorée parce qu'il est impossible que le cœur de rotateur se fissure. Le cœur de rotateur (10, 25) doté d'un stratifié de blocs de cœur sensiblement cylindriques (12, 13, 26, 27, 28) et d'aimants (20) est caractérisé en ce que les blocs de cœur (12, 13, 26, 27, 28) comportent des trous d'accueil d'aimants (16, 17) s'étendant dans la direction axiale audits blocs (12, 13, 26, 27, 28), les aimants (20) sont accueillis dans les trous d'accueil d'aimants (16, 17) et fixés avec de la résine, et en ce que la ou les positions axiales de la ou des surfaces limites de blocs de cœur (23, 30, 30a) le long desquelles lesdits blocs (12, 13, 26, 27, 28) sont en contact les uns avec les autres (mutuellement) et la ou les positions axiales de la ou des surfaces limites des aimants (22, 31) le long desquelles les aimants (20) sont en contact les uns avec les autres (mutuellement) sont différentes.
