An artificial cardiac assist device (VAD) mudziyo unoshandiswa kubatsira kana kutsiva kushanda kwemoyo uye unowanzoshandiswa kurapa varwere vane moyo kukundikana. Mumidziyo yekubatsira mwoyo yakagadzirwa, iyocoreless motachinhu chakakosha chinoburitsa simba rekutenderera kusimudzira kuyerera kweropa, nekudaro kuchengetedza kutenderera kweropa remurwere. Ichi chinyorwa chichakurukura dhizaini uye mashandisirwo emakoreless mota mumapombi eropa ekugadzira.
Chekutanga pane zvese, dhizaini yeiyo coreless mota inoda kutarisisa nharaunda yayo yakakosha yekushanda mumapombi eropa ekugadzira. Sezvo michina yekubatsira yemoyo yekugadzira inoda kushanda kwenguva yakareba, mota dzisina coreless dzinofanirwa kushanda, dzakagadzikana uye dzakavimbika. Mukuwedzera, sezvo kushanda kwayo kuchida kutarisana zvakananga neropa, dhizaini ye coreless motor inodawo kufunga nezve biocompatibility uye anti-thrombotic properties. Naizvozvo, ma coreless motors anowanzo shandisa zvakakosha zvinhu uye machira kuti ave nechokwadi chekushanda kwavo kwenguva refu kwakagadzikana muropa.
Kechipiri, kushandiswa kwema coreless motors mumapombi eropa ekugadzira kunofanirwa kufunga nezve maitiro ayo pakuyerera kweropa. Iyo coreless mota inotyaira kuyerera kweropa kuburikidza ne centrifugal simba rinogadzirwa nekutenderera, saka dhizaini yayo inofanirwa kufunga nezve kubata kweropa zvinyoro nyoro kudzivirira yakawandisa shear simba uye kudzvanywa paropa. Panguva imwecheteyo, kushanda kweiyo coreless mota kunoda kuenzanisa circadian rhythm yemuviri wemunhu kuve nechokwadi kugadzikana uye kunoshanda kutenderera kweropa.
Mumashandisirwo anoshanda, dhizaini uye kushandiswa kwema coreless motors mumapombi eropa ekugadzira zvinoda kushanda pamwe chete nezvimwe zvikamu, senge ma sensors uye masystem ekudzora. Kuburikidza nekunyatso kudzora uye kutarisa, iyo coreless mota inogona kuwana chaiyo kurongeka kwekuyerera kweropa uye kumanikidza kuzadzisa zvinodiwa nevarwere vakasiyana.
Muchidimbu, dhizaini uye mashandisirwo emakoreless mota mumapombi eropa ekugadzira inyaya yakaoma uye yakakosha engineering inoda kutariswa kwakadzama kwezvinhu, biocompatibility, fluid mechanics nezvimwe zvinhu. Nekuenderera mberi kwekufambira mberi kwehunyanzvi hwekurapa, kushandiswa kwema coreless motors mune yekugadzira moyo yekubatsira zvishandiso kuchawedzerwa nekugadziridzwa, zvichipa zvakanyanya kushanda uye zvakachengeteka marapirwo evarwere vemoyo.
