Nkumukoresha,moterini kimwe mubicuruzwa byingenzi bya mechatronics, bikoreshwa cyane muri sisitemu zitandukanye zo kugenzura ibyikora. Hamwe niterambere rya microelectronics hamwe nikoranabuhanga rya mudasobwa, ibyifuzo bya moteri yintambwe biriyongera umunsi kumunsi, kandi bikoreshwa mubice bitandukanye byubukungu bwigihugu.
01 Nikimoteri
Intambwe ya moteri ni igikoresho cya elegitoroniki gihindura amashanyarazi mu buryo butaziguye. Mugenzura uko bikurikirana, inshuro n'umubare w'amashanyarazi akoreshwa kuri coil ya moteri, kuyobora moteri ya moteri, umuvuduko no kuzenguruka birashobora kugenzurwa. Hatabayeho gukoresha uburyo bwo kugenzura ibitekerezo bifunze hamwe no kumva imyanya, umwanya uhamye no kugenzura umuvuduko urashobora kugerwaho ukoresheje uburyo bworoshye, buhendutse buhendutse bwo kugenzura bugizwe na moteri yintambwe hamwe numushoferi uherekeza.
02 moteriimiterere shingiro nihame ryakazi
Imiterere y'ibanze ：
Ihame ryakazi: umushoferi wintambwe ukurikije icyerekezo cyo hanze cyerekanwe hamwe nicyerekezo cyerekezo, binyuze mumuzenguruko wacyo wimbere, ugenzure intambwe ya moteri ikurikirana mugihe runaka gikurikiranye imbere cyangwa gisubiramo ingufu, kugirango moteri igende / ihindurwe, cyangwa ifunze.
Fata urugero rwa 1.8 dogere ibyiciro bibiri byintambwe nkurugero: mugihe impinduramatwara zombi zifite imbaraga kandi zishimye, moteri isohoka moteri izahagarara kandi ifunze mumwanya. Umuriro ntarengwa uzakomeza moteri ifunze kumurongo wagenwe niwo ufata torque. Niba ikigezweho muri kimwe mu byerekezo cyerekejwe, moteri izunguruka intambwe imwe (1.8 dogere) mu cyerekezo runaka.
Muri ubwo buryo ,, niba ikigezweho mubindi byerekezo bihindura icyerekezo, moteri izunguruka intambwe imwe (dogere 1.8) muburyo bunyuranye bwambere. Iyo imiyoboro inyuze muri coil ihindurwamo ikurikiranye kugirango yishime, moteri izunguruka mu ntambwe ikomeza mu cyerekezo cyatanzwe kandi neza cyane. Kuri dogere 1.8 yicyiciro cya kabiri intambwe yo guhinduranya moteri yicyumweru ifata intambwe 200.
Moteri y'ibyiciro bibiri ifite moteri ebyiri zo guhinduranya: bipolar na unipolar. Moteri ya Bipolar ifite igiceri kimwe gusa kizunguruka kuri buri cyiciro, moteri ikomeza kuzunguruka yumuyaga muri coil imwe kugirango ihindurwe bikurikiranye, igishushanyo cyumuzunguruko gisaba ibyuma umunani bya elegitoronike kugirango bihindurwe bikurikiranye.
Moteri ya Unipolar ifite ibice bibiri bizunguruka bya polarite itandukanye kuri buri cyiciro, na moteri
kuzunguruka ubudahwema guhinduranya imbaraga zibiri zingana kumurongo umwe.
Inzira ya disiki yashizweho kugirango isabe ibintu bine gusa bya elegitoroniki. Muri bipolar
uburyo bwo gutwara, ibisohoka bya moteri byiyongereyeho 40% ugereranije nu
uburyo bwo gutwara unipolar kuberako ibizunguruka bya buri cyiciro birashimishije 100%.
03, Umutwaro wimodoka
A. Umutwaro mukanya (Tf)
Tf = G * r
G: Kuremerera uburemere
r: radiyo
B. Inertia umutwaro (TJ)
TJ = J * dw / dt
J = M * (R12 + R22) / 2 (Kg * cm)
UMWIGISHA: Imizigo
R1: Radius yimpeta yo hanze
R2: Radius yimpeta y'imbere
dω / dt: Kwihuta kwinguni
04, intambwe ya moteri yihuta-torque umurongo
Umuvuduko-torque umurongo ni imvugo yingenzi yerekana ibisohoka biranga intambwe
moteri.
A. Intambwe ikora moteri ikora
Umuvuduko agaciro ka moteri ya moteri yintambwe mugihe runaka.
n = q * Hz / (360 * D)
n: ivugurura / amasegonda
Hz: Agaciro kenshi
D: Gutwara umuzunguruko interpolation agaciro
q: intambwe ya moteri yintambwe
Kurugero, moteri yintambwe ifite inguni ya 1.8 °, hamwe na 1/2 interpolation(ni ukuvuga 0,9 ° kuri buri ntambwe), ifite umuvuduko wa 1.25 r / s kuri frequency ikora ya 500 Hz.
B. Intambwe ya moteri yo kwikorera
Agace moteri yintambwe irashobora gutangirwamo igahagarikwa muburyo butaziguye.
C. Agace gakoreramo
Muri kano gace, moteri yintambwe ntishobora gutangira cyangwa guhagarara muburyo butaziguye. Moteri ikomezakariya gace kagomba kubanza kunyura mukarere-gatangiriraho hanyuma kwihuta kugera kuriagace gakoreramo. Muri ubwo buryo, moteri yintambwe muri kano gace ntishobora guhagarikwa feri,bitabaye ibyo biroroshye gutera moteri yintambwe ntambwe, igomba kubanza kwihuta kuriagace ko gutangiriraho hanyuma feri.
D. Intambwe ya moteri ntarengwa yo gutangira inshuro
Moteri nta-umutwaro leta, kugirango umenye neza ko intambwe yintambwe idatakaza imikorere yintambwe yainshuro ntarengwa.
E. Intambwe ya moteri ntarengwa ikora inshuro
Umubare ntarengwa wa pulse moteri ishimishwa no gukora nta gutakaza intambwemunsi y'umutwaro.
F. Intambwe ya moteri itangira torque / gukurura-torque
Guhura na moteri yintambwe mugihe runaka cya pulse kugirango utangire utangire kwiruka, ntagutakaza intambwe yumutwaro ntarengwa.
G. Intambwe ya moteri ikora torque / gushushanya
Umutwaro ntarengwa wuzuza imikorere ihamye ya moteri yintambwe kuri ainshuro zimwe za pulse nta gutakaza intambwe.
05 Kwihuta kwimodoka yihuta / kugenzura umuvuduko
Iyo intambwe ya moteri ikora inshuro nyinshi mumuvuduko-torque umurongo uhorahoakarere gakoreramo, uburyo bwo kugabanya moteri gutangira cyangwa guhagarika kwihuta cyangwa kwihutaigihe, kugirango moteri ikore igihe kirekire muburyo bwiza bwihuta, bityo byongereigihe cyiza cyo gukora cya moteri kirakomeye cyane.
Nkuko bigaragara ku gishushanyo gikurikira, imbaraga za torque ziranga umurongo wa moteri yintambwe niumurongo ugororotse ugororotse ku muvuduko muke; ku muvuduko mwinshi, umurongo ugabanuka cyanebitewe ningaruka za inductance.
Turabizi ko umutwaro wa moteri yintambwe ari TL, tuvuge ko dushaka kwihuta kuva F0 kugeza F1 muriigihe gito (tr), nigute ushobora kubara igihe gito tr?
(1) Mubisanzwe, TJ = 70% Tm
(2) tr = 1.8 * 10 -5 * J * q * (F1-F0) / (TJ -TL)
(3) F (t) = (F1-F0) * t / tr + F0, 0
B. Kwihuta kugaragara muburyo bwihuse
(1) Mubisanzwe
TJ0 = 70% Tm0
TJ1 = 70% Tm1
TL = 60% Tm1
(2)
tr = F4 * Muri [(TJ 0-TL) / (TJ 1-TL)]
(3)
F (t) = F2 * [1 - e ^ (- t / F4)] + F0, 0
F2 = (TL-TJ 0) * (F1-F0) / TJ 1-TJ 0)
F4 = 1.8 * 10-5 * J * q * F2 / (TJ 0-TL)
Inyandiko.
J yerekana inertia yizunguruka ya moteri ya rot munsi yumutwaro.
q ni ukuzenguruka inguni ya buri ntambwe, niyo ntambwe inguni ya moteri yintambwe muri
ikibazo cya disiki yose.
Mubikorwa byo kwihuta, hindura gusa umuvuduko wo hejuru wihuta ushobora kuba
kubarwa.
06 intambwe ya moteri yinyeganyeza n urusaku
Mubisanzwe nukuvuga, moteri yintambwe mubikorwa bidafite imizigo, mugihe moteri ikora inshuroni hafi cyangwa bingana na moteri ya rotor yihariye inshuro izumvikana, ubushake bukomeyebibaho bivuye ku ntambwe.
Ibisubizo byinshi kuri resonance:
A. Irinde agace kinyeganyega: kugirango moteri ikora moteri itagwa imbereurwego rwo kunyeganyega
B. Emera uburyo bwo gutwara ibice: Koresha micro-intambwe yo gutwara kugirango ugabanye kunyeganyega na
kugabanya umwimerere intambwe imwe muntambwe nyinshi kugirango wongere imyanzuro ya buri
intambwe ya moteri. Ibi birashobora kugerwaho muguhindura icyiciro nikigereranyo cya moteri.
Microstepping ntabwo yongerera intambwe intambwe, ariko ituma moteri ikora cyane
neza kandi hamwe n'urusaku ruke. Umuriro muri rusange uri munsi ya 15% kubikorwa byintambwe
kuruta kubikorwa byuzuye, na 30% munsi ya sine wave igenzura.
