Passive contactless levitated axial flux machine with permanent magnetic disc rotor for a implantable ventricular assist device

The scissor between available heart donations and people affected by heart insufficiency opens wider and wider. Good results to support the diseased heart were offered by artificial therapy approaches like a mechanical system that is connected to the left ventricle and works parallel to the heart muscle. The essay presents the designing and optimisation process of such a mechanical blood pump. A innovative design using magnetic and hydraulic forces to avoid mechanical bearings is presented. Built as a brushless axial flux machine it results in a highly integrated drive component with minimized axial length and passive and wearless levitation
