| Outline of Final Research Achievements |
A rotor dynamics simulation considering effect of fluid dynamics was carried out to design a 5-DOF controlled magnetically levitated motor for pediatric ventricular assit device (VAD). A geometric parameter, number of coil turns and pole number of permanent magnets were optimized based on a three dimensional magnetic field analysis. A miniaturized 5-degrees of freedom (5-DOF) controlled maglev motor which has an outer diameter of 22 mm and height of 33 mm was developed. Motor static suspension performances and rotating torque capacity were examined. A magnetic levitation and rotation performances were evaluated with a developed test rig. The rotor was magnetically levitated and rotated up to 4500 rpm without mechanical contact. The developed 5-DOF controlled maglev motor indicated sufficient magnetic levitation and rotation performance for use in pediatric VAD.
