Monga chinthu chopangira digito, stepper motor imagwiritsidwa ntchito kwambiri pamachitidwe owongolera. Ogwiritsa ntchito ambiri ndi abwenzi pogwiritsira ntchito ma stepper motors amamva kuti galimotoyo imagwira ntchito ndi kutentha kwakukulu, mtima umakayikira, sadziwa ngati chodabwitsa ichi ndi chachilendo. M'malo mwake, kutentha ndi chinthu chodziwika bwino cha ma stepper motors, koma ndi kutentha kotani komwe kumadziwika kuti ndizabwinobwino, komanso momwe mungachepetse kutentha kwa mota ya stepper?
一, kuti mumvetse chifukwa chake stepper motor itenthetsa.
Kwa mitundu yonse ya ma stepper motors, mkati mwake mumapangidwa ndi chitsulo chapakati ndi coil yokhotakhota. Kulimbana ndi mphepo, mphamvu idzatulutsa kutayika, kukula kwa kutaya ndi kukana ndipo panopa ndi yofanana ndi lalikulu, izi ndi zomwe timazitcha kutayika kwa mkuwa, ngati panopa sizomwe zimayendera DC kapena sine wave, zidzatulutsanso kuwonongeka kwa harmonic; core hysteresis eddy panopa zotsatira, mu alternating maginito kutulutsanso kutayika, kukula kwa zinthu, panopa, pafupipafupi, voteji zokhudzana, amene amatchedwa chitsulo imfa. Kutayika kwa mkuwa ndi kutayika kwachitsulo kudzawonetsedwa mu mawonekedwe a kutentha kwa kutentha, motero kumakhudza mphamvu ya galimoto.
Ma motor steping nthawi zambiri amatsata kulondola kwa malo komanso kutulutsa kwa torque, kuchita bwino kumakhala kotsika, komwe kumakhala kokulirapo, komanso zigawo zazikulu zolumikizirana, ma frequency akusinthana ndi liwiro komanso kusintha, kotero kuti ma motors oponda nthawi zambiri amakhala ndi kutentha, ndipo zinthu ndizovuta kwambiri kuposa ma mota wamba wa AC.
二、 stepper motor kuwongolera kutentha mkati mwazoyenera.
Njinga kutentha analola kuti, makamaka zimadalira pa galimoto mkati kutchinjiriza mlingo. Kutsekemera kwamkati sikuwonongeka mpaka kutentha kwambiri (pamwamba pa madigiri 130). Choncho malinga ngati mkati si upambana madigiri 130, galimoto si kuonongeka, ndiyeno kutentha pamwamba adzakhala pansi madigiri 90. Choncho, kutentha kwa stepper motor pamwamba pa madigiri 70-80 ndikwachilendo. Njira yosavuta yoyezera kutentha ndi thermometer, mukhoza kuweruza mozama: ndi dzanja lingathe kukhudza masekondi oposa 1-2, osapitirira madigiri 60; ndi dzanja likhoza kukhudzidwa, pafupifupi madigiri 70-80; madontho ochepa a madzi mwamsanga vaporized, ndi madigiri oposa 90; ndithudi, mungagwiritsenso ntchito kutentha mfuti kuti azindikire.
三, Kuwotchera kwa stepper motor ndikusintha liwiro.
Mukamagwiritsa ntchito ukadaulo wamagalimoto okhazikika, ma stepper motor mumayendedwe okhazikika komanso otsika, yapano imakhalabe yokhazikika kuti ikhale yotulutsa nthawi zonse.
Liwiro likafika pamlingo wina, kuthekera kobwerera mkati mwa mota kumakwera, komweko kumachepera pang'onopang'ono, ndipo torque nayonso imachepa. Choncho, kutentha kwa kutentha chifukwa cha kutaya mkuwa kumagwirizana ndi liwiro.
Kutentha kwa kutentha nthawi zambiri kumakhala kothamanga kwambiri komanso kocheperako komanso kutsika kwambiri. Koma kutayika kwachitsulo (ngakhale kagawo kakang'ono) kusintha sikuli choncho, ndipo kutentha kwa injini yonse ndi chiwerengero cha ziwirizo, kotero zomwe zili pamwambazi ndizochitika wamba.
四, mphamvu ya kutentha
Kutentha kwa injini, ngakhale nthawi zambiri sikukhudza moyo wagalimoto, makasitomala ambiri sayenera kulabadira. Komabe, kutentha kwakukulu kudzabweretsa zotsatira zina zoipa.
Monga mbali zamkati za motor matenthedwe kukulitsa coefficient osiyana structural kupsyinjika chifukwa cha kusintha mkati mpweya kusiyana ndi kusintha pang'ono adzakhudza kuyankha amphamvu a galimoto, mkulu-liwiro adzakhala zosavuta kutaya sitepe.
Chitsanzo china ndi chakuti nthawi zina sizilola kutentha kwambiri kwa injini, monga zida zachipatala ndi zida zoyesera zolondola kwambiri. Choncho, kutentha kwa injini kuyenera kukhala koyenera kulamulira.
五、 kuchepetsa kutentha kwa injini.
Kuchepetsa kutentha ndi kuchepetsa mkuwa imfa ndi chitsulo imfa. Kuchepetsa zomvetsa mkuwa ndi mayendedwe awiri, kuchepetsa kukana ndi panopa, zomwe zimafuna kusankha kukana yaing'ono ndi oveteredwa panopa mmene tingathere posankha Motors ang'onoang'ono, awiri gawo Motors, angagwiritsidwe ntchito motere Motors alibe kufanana galimoto.
Koma izi nthawi zambiri zimatsutsana ndi zofunikira za torque ndi liwiro lalikulu.
Pakuti galimotoyo yasankhidwa, iyenera kugwiritsa ntchito mokwanira ntchito yoyendetsa yokhayokha yomwe imagwira ntchito pakalipano ndi ntchito yapaintaneti, yoyambayo imachepetsa mphamvu yamagetsi pamene galimotoyo ili pamalo amodzi, yomalizayo imangodula panopa.
Kuphatikiza apo, kuyendetsa bwino kugawikana chifukwa cha mawonekedwe apano omwe ali pafupi ndi sinusoidal, ma harmonics ochepa, kutentha kwagalimoto kudzakhala kochepa. Palibe njira zambiri zochepetsera kutayika kwachitsulo, mphamvu yamagetsi imagwirizana ndi mota yamagetsi okwera kwambiri, ngakhale ibweretsa mawonekedwe othamanga kwambiri, komanso kubweretsa kutentha.
Choncho, tiyenera kusankha yoyenera pagalimoto voteji mlingo, kutenga mkulu liwiro, kusalala ndi kutentha, phokoso ndi zizindikiro zina.
