Radial position active control of double stator axial gap self-bearing motor for pediatric VAD

In the last decade, ventricular assist devices (VADs) such as continuous flow rotary blood pumps have been successfully applied to advanced heart disease patients for bridge to transplantation and destination therapy. The success with VAD technology has recently increased significant clinical need f...
