Patent number: 11592059Abstract: A thrust magnetic bearing device includes: a thrust disc fixed to a rotating body; and a pair of electromagnets provided so as to sandwich the thrust disc and be spaced apart from the thrust disc in a direction along a rotation axis. Each of the pair of electromagnets includes: a coil wound around the rotation axis of the rotating body; and a ring-shaped core accommodating the coil. The core includes a slit which is located at at least one circumferential position of the core and extends from an outside outer peripheral surface as a starting point toward a center of the core. The slit is formed in a range including at least an inside outer peripheral surface.Type: GrantFiled: December 14, 2018Date of Patent: February 28, 2023Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Ryoma Yamamoto, Yoshihiko Ozaki, Kentaro Sakata, Masanori Kuroda, Masashi Sawada
