Kugwiritsa ntchito ma stepper motors kudzakumana ndi zovuta zisanu ndi zinayi

1, momwe mungayendetsere njira yozungulirastepper mota?

Mukhoza kusintha chizindikiro cha mlingo wa kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Mutha kusintha ma waya agalimoto kuti musinthe njira, motere: Kwa ma motors agawo awiri, gawo limodzi lokha la mawotchi amtundu wamagetsi amatha kukhala, monga A + ndi A- kuwombola. Kwa ma motors a magawo atatu, palibe gawo limodzi la kusinthana kwa mzere wamagalimoto, koma kuyenera kukhala kusinthana kotsatizana kwa magawo awiri, monga kusinthana kwa A + ndi B +, A- ndi B- kusinthanitsa.

2, ndistepper motaphokoso makamaka lalikulu, palibe mphamvu, ndi galimoto kugwedera, bwanji?

Izi zimachitika chifukwa stepper galimoto ntchito mu oscillation zone, yankho.

A, sinthani ma frequency a CP kuti mupewe malo ozungulira.

B, kugwiritsa ntchito magawano pagalimoto, kotero kuti gawo laling'ono limachepetsedwa, likuyenda bwino.

3, pamenestepper motaimayatsidwa, shaft yamoto sitembenuka kuti ichite bwanji?

Pali zifukwa zingapo zomwe injini simazungulira.

A, kuzungulira kotsekereza kolemetsa

B, kaya galimoto yawonongeka

C, ngakhale galimotoyo ili pa intaneti

D, kaya ndi chizindikiro cha CP mpaka ziro

4, stepper motor driver mphamvu, mota ikugwedezeka, simatha kuthamanga, bwanji?

Mukakumana ndi izi, fufuzani kaye mapindikidwe agalimoto ndi kugwirizana kwa dalaivala ndipo palibe kugwirizana kolakwika, monga ngati palibe kugwirizana kolakwika, ndiyeno fufuzani kuti mafupipafupi amtundu wa pulse ndi apamwamba kwambiri, kaya kamangidwe kake kakukwera si koyenera.

5, momwe mungapangire ntchito yabwino ya stepper motor lift curve?

Liwiro la stepper motor likusintha ndi chizindikiro cha pulse. Mwachidziwitso, ingopatsa driver chizindikiro. Iliyonse ipatse dalaivala kugunda (CP), mota ya stepper imazungulira kagawo kakang'ono (kugawa kwa gawo logawika magawo). Komabe, chifukwa chakuchita kwa stepper motor, chizindikiro cha CP chimasintha mwachangu kwambiri, chowongoleracho sichingafanane ndi kusintha kwa ma siginecha amagetsi, omwe amatulutsa masitepe otsekereza komanso otayika. Chifukwa chake stepper motor kuti ikhale yothamanga kwambiri, payenera kukhala njira yofulumira, pakuyimitsa payenera kukhala njira yotsika. General liwiro ndi kutsika lamulo lomwelo, zotsatirazi liwiro mwachitsanzo: liwiro ndondomeko imakhala kulumpha pafupipafupi kuphatikiza liwiro pamapindikira (ndi mosemphanitsa). Mafupipafupi oyambira sayenera kukhala akulu kwambiri, apo ayi adzatulutsanso njira yotsekereza komanso yotayika. Ma curve othamanga ndi otsika nthawi zambiri amakhala ma curve owoneka bwino kapena ma curve osinthika, ndithudi, amathanso kugwiritsa ntchito mizere yowongoka kapena ma curve a sine, etc. Exponential pamapindikira mu leni pulogalamu mapulogalamu ndondomeko ndi zovuta, zambiri masamu pasadakhale zokhazikika kusungidwa mu kukumbukira kompyuta izo, ntchito ndondomeko mwachindunji anasankha.

6, stepper mota yotentha, kutentha kwabwinoko ndi kotani?

Kutentha kwa mota ndikokwera kwambiri kumapangitsa kuti maginito a injiniyo awonongeke, zomwe zimapangitsa kutsika kwa torque komanso kutayika kwa masitepe. Chifukwa chake, kutentha kwakukulu kovomerezeka kwakunja kwa mota kuyenera kutengera demagnetization point yazinthu zosiyanasiyana zamaginito. Nthawi zambiri, demagnetization point ya zida zamaginito ndi yopitilira 130 digiri Celsius, ndipo zina ndizokwera kwambiri. Choncho stepper galimoto maonekedwe 80-90 digiri Celsius ndi zachilendo kwathunthu.

7, magawo awiri stepper mota ndi anayi gawo stepper mota pali kusiyana kotani? 

Ma motors agawo awiri ali ndi ma windings awiri okha pa stator ndi mawaya anayi otuluka, 1.8 ° pa sitepe yonse ndi 0,9 ° pa sitepe imodzi. Poyendetsa, ndikwanira kulamulira kayendedwe kameneka ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka magawo awiri. Ngakhale zinayi gawo stepper galimoto mu stator ali windings anayi, pali mawaya asanu ndi atatu, sitepe lonse ndi 0,9 °, theka sitepe 0,45 °, koma dalaivala ayenera kulamulira windings anayi, dera ndi zovuta. Chifukwa chake, magawo awiri amagetsi okhala ndi magawo awiri, ma mota anayi magawo asanu ndi atatu ali ndi magawo ofanana, angapo, njira zitatu zolumikizirana. Kulumikizana kofananira: magawo anayi opindika awiri awiri, kukana kokhotakhota ndi inductance kumachepetsa mokulira, mota imayenda bwino, liwiro lalikulu ndi torque yayikulu, koma mota imayenera kulowetsa kawiri zomwe zidavotera pano, kutentha, kuchuluka kwamphamvu kwagalimoto kumawonjezeka. Mukagwiritsidwa ntchito motsatizana, kukana kwa mphepo ndi inductance kumawonjezeka kwambiri, galimotoyo imakhala yokhazikika pa liwiro lochepa, phokoso ndi mbadwo wa kutentha ndizochepa, zofunikira pa galimotoyo sizokwera, koma kutayika kwa torque kwachangu ndi kwakukulu. Chifukwa chake ogwiritsa ntchito amatha kusankha njira yolumikizira ma waya anayi magawo asanu ndi atatu malinga ndi zofunikira.

8, galimoto ndi zinayi gawo mizere isanu ndi umodzi, ndi stepper galimoto dalaivala bola njira yothetsera mizere inayi, momwe ntchito?

Kwa injini yamagetsi yamagetsi a magawo anayi, phokoso lapakati la mawaya awiri olendewera osalumikizidwa, mawaya ena anayi ndi dalaivala amalumikizidwa.

9, kusiyana pakati pa ma motors othamanga ndi ma hybrid stepper motors?

Mosiyana ndi kapangidwe ndi zinthu, ma hybrid motors ali ndi zida zamtundu wa maginito osakhazikika mkati, motero ma hybrid stepper motors amayenda bwino, ndi mphamvu yoyandama yayikulu komanso phokoso lotsika.
