Matoorada ultrasonic Piezoelectric waxay leeyihiin laba faa'iidooyin oo muhiim ah, kuwaas oo ah cufnaanta tamarta sare iyo qaab-dhismeedkooda fudud, kuwaas oo labaduba gacan ka geysta yaraantooda.Waxaan dhisnay mooto yar oo ultrasonic ah anagoo adeegsanayna stator leh mug qiyaastii hal millimitir kuyuub ah.Tijaabooyinkeennu waxay muujiyeen in matoorka tusaalaha ahi uu dhaliyo wareeg ka badan 10 μNm oo leh hal millimitir cubic stator.Matoorkan cusub hadda waa matoorka ugu yar ee ultrasonic ee lagu soo saaray wareeg wax ku ool ah.
Mashruucyada yar yar ayaa looga baahan yahay codsiyo badan, oo u dhexeeya moobilka iyo aaladaha la xidhi karo ilaa aaladaha caafimaadka ee ugu yar ee waxyeeleeya.Si kastaba ha ahaatee, xaddidaadyada la xidhiidha been-abuurkooda ayaa xaddiday geyntooda hal-mil mitir.Matoorada korantada ee ugu caansan waxay u baahan yihiin yaraynta qaybo badan oo adag sida gariiradaha, magnets, iyo bearings, oo ay muujiyaan kala daadsanaan daran oo ay ugu wacan tahay qolofta.Matoorada Electrostatic-ku waxay awood u siinayaan miisaan aad u fiican iyagoo isticmaalaya tignoolajiyada nidaamyada microelectromechanical (MEMS), laakiin awoodooda wadista daciifka ah ayaa xaddiday horumarkooda dheeraadka ah.
Matoorada ultrasonic Piezoelectric ayaa la filayaa inay noqdaan micromotors-waxqabad sare sababtoo ah cufnaanta sare ee qulqulka iyo qaybaha fudud.Matoorka ugu yar ee ultrasonic jira ee la soo sheegay ilaa maanta wuxuu leeyahay qayb macdan ah oo leh dhexroor 0.25 mm iyo dherer 1 mm.Si kastaba ha ahaatee, cabbirkeeda wadarta ah, oo ay ku jiraan farsamaynta horudhaca, waxay gaaraysaa 2-3 mm, qiimihiisu aad ayuu u yar yahay (47 nNm) si loogu isticmaalo hawl wadeen codsiyo badan.
Tomoaki Mashimo, oo ah cilmi-baare ka tirsan jaamacadda Toyohashi ee Tiknoolajiyada, ayaa soo saaraysay matoor yar oo ultrasonic ah oo leh hal millimitir cubic stator, sida ku cad sawirka 1, sidoo kale waa mid ka mid ah matoorada ultrasonic ugu yar ee abid la dhisay.Stator-ka, kaas oo ka kooban cube macdan ah oo leh dalool-god iyo walxo saxan-piezoelectric ah oo ku dheggan dhinacyadeeda, waa la miisaami karaa iyada oo aan loo baahnayn wax farsamooyin gaar ah ama hababka isku-ururinta.Matoorka nooca yar yar ee ultrasonic wuxuu gaadhay wareeg wax ku ool ah oo ah 10 μNm (Haddii jiidhu leeyahay radius 1 mm, matoorku wuxuu qaadi karaa miisaan 1-g) iyo xawaar xagal ah oo ah 3000 rpm qiyaastii 70 Vp-p.Qiimaha wareeggu wuxuu 200 jeer ka weyn yahay matoorada yaryar ee jira, waana mid aad u macquul ah oo lagu wareejinayo walxaha yaryar sida dareemayaasha yaryar iyo qaybaha farsamada.
