Optimization Design of Magnetically Suspended System for the BiVACOR Total Artificial Heart

The BiVACORdevice is a third generation rotary total artificial heart under development to treat end stage cardiovascular disease. Non-contact suspension and rotation of the impeller of the blood pump was achieved by a combination of a permanent magnet hybrid type magnetic bearing and an axial flux brush-less DC motor. Moreover, according to a series of animal trials, functionality of the proposed magnetic system in the total artificial heart application was clarified.
