3.2 ultrasonic lub cev muaj zog
Ultrasonic motors (USM) siv cov nyhuv piezoelectric ntawm piezoelectric cov ntaub ntawv ua rau cov khoom me me sib xws (kev sib nraus heev dua 20 kHz) hauv ultrasonic zaus zaus, los ntawm stator thiab rotor (los yog mov) Cov kev sib txhuam ntawm tus stator converts microscopic kev co ntawm tus stator mus rau hauv txoj kev ua ib qho kev hloov ntawm txoj kev ua kom (lossis txoj kev tawm suab) ntawm lub rotor (los yog mov). Nws rhuav tshem lub tswv yim ntawm cov tsoos cav uas tau txais kev sib hloov ceev thiab torque los ntawm cov kab mob electromagnetic, thiab nws kuj yog ib qho tshiab zoo tshaj plaws nyob rau hauv txoj kev loj hlob ntawm lub tshuab fais fab micro.
Piv rau cov pa roj carbon monoxide, ultrasonic motors muaj ntau qhov zoo:
(1) Tus qauv yog yooj yim, thiab nws yog ob qho ntawm ob yam yooj yim: lub vibrating tivthaiv thiab kev txav nrog;
(2) Lub zog rau ib ntu yog 10 npaug ntawm cov pa tsheb ntawm tib lub ntim;
(3) Qhov kev ua qeeb qeeb qeeb yog qhov zoo, qhov ceev tau hloov mus rau xoom, thiab cov loj torque tuaj yeem ncaj qha zis ntawm qeeb qeeb;
(4) Lub braking torque loj thiab tsis tas yuav tsum nres ntxiv;
(5) Lub sij hawm mechanical tsis tu ncua me me thiab qhov kev ua tau zoo yog qhov zoo;
(6) Yog tsis muaj hlau nplaum thiab hluav taws xob, tsis muaj kev cuam tshuam electromagnetic thiab suab nrov electromagnetic.
Tam sim no, ntau ultrasonic motors tau commercialised nyob hauv ntau lub teb chaws hauv lub teb chaws txawv teb chaws xws li Nyiv. Cov khoom tshiab rau ultrasonic motors ntawm Canon, Panasonic, thiab Hitachi tau siv hauv cov koob yees duab siab, camcorders, thiab kho qhov muag twj ywm. Txoj kev loj hlob ntawm kev siv tshuab ultrasonic cav yog los ntxiv txhim kho kev lag luam.
Ultrasonic motors siv lub ntsiab cai tshiab thiab cov qauv, tsis xav tau cov hlau nplaum thiab coils, tab sis siv cov nyhuv piezoelectric ntawm piezoelectric cov ntaub ntawv thiab ultrasonic kev co mus ncaj nraim mus rau cov lus tsa suab thiab kev quab yuam (lub caij). Nws rhuav lub tswvyim ntawm lub tshuab ua haujlwm kom dhau deb tau qhov kev sib hloov ceev thiab lub zog ntawm electromagnetic teebmeem, thiab yog ib lub high-tech nyob rau hauv lub forefront ntawm kev tshawb fawb ntiaj teb tam sim no. Vim yog lub ultrasonic, lub tshuab muaj ntau yam ntxwv uas cov tshuab hluav taws xob electromagnetic tsis muaj. Txawm hais tias nws tsim thiab kev loj hlob tsuas muaj 20 xyoo keeb kwm, nws tau ua tiav raws li kev lag luam ntawm kev ua lag luam, kev tsav tsheb, tsheb, qhov tseeb, cov khoom kho mob, thiab cov tshuab ntsuas me. .
