| Abstract |
This totally implantable artificial heart developed by us is characterized by a double pusher-plate system, moving two sacks corresponding to both ventricles. The transformation of the rotating movement of the motor in the linear pusher-plates displacement is realized by a planetary roller-screw. The chosen electrical motor is a brushless DC one, characterized by high performances integrated components. The PM are directly fixed on the screw nut, which is the rotor yoke, in order to reduce the total system inertia. The paper describes the main characteristics of the motor, the power electronics and the control. The artificial heart has been implanted several times on animals. |
