Abstract

Buluş, stator gövdesi (2), akım düzleştirici (9), sabit dönüştürücü (5), rotor (7), rotor 5 üstüne yerleştirilmiş bıçaklar (6) ve rotor içme yerleştirilmiş bıçaklar (8) parçalarının yanı sıra fırçasız doğru akım motorunun parçalarından olan stator sanmlan (3), pozisyon sensörleri (4), daimi mıknatısları (13) ve mekanik rulman ya da manyetik rulman içeren eksenel akımlı kalp pompası (1) ile ilgilidir. Eksenel akım kalp pompasının (1) özelliği, kana akım hızı kazandırmak ve kanın basıncını ayarlamak için rotor üstüne yerleştirilmiş 10 bıçaklarının (6) ve rotor içme yerleştirilmiş bıçaklarının (8) döner hareketiyle, fırçasız doğru akım motorunun stator sarınımlarının (3) ve rotordaki (7) daimi mıknatısların (13) etkileşimiyle üretilen hareket enerjisinin kana kinetik enerji olarak aktarılmasıdır.The invention includes the parts of the stator body (2), the current straightener (9), the stationary converter (5), the rotor (7), the blades (6) placed on the rotor 5 and the blades (8) placed inside the rotor, as well as the parts of the brushless direct current motor. Stator windings (3), position sensors (4), permanent magnets (13) and axial-flow heart pump (1) containing mechanical bearing or magnetic bearing. The feature of the axial flow heart pump (1) is that the stator windings of the brushless direct current motor (3) and the rotor (7) are rotated by the rotating movement of the 10 blades (6) placed on the rotor and the blades (8) placed inside the rotor to give the blood flow rate and adjust the blood pressure ) is the transfer of motion energy generated by the interaction of permanent magnets (13) to the blood as kinetic energy.
