Mapangidwe a 4-pole ndi olimba kwambiri kuposa ofanana ndi 2-pole, koma amathanso kutenga malo omwewo ndi kulemera kwake.Greg Dutfield wochokera ku maxon UK akufotokoza.
Ma mota a 4-pole ali ndi zabwino posankha ma motor DC ang'onoang'ono kuti agwiritse ntchito kuyambira pazamlengalenga mpaka pakubowola bwino.Mapangidwe a 4-pole ndi olimba kwambiri kuposa ofanana ndi 2-pole, koma amathanso kutenga malo omwewo ndi kulemera kwake.Greg Dutfield wochokera ku maxon UK akufotokoza.
Kwa ma mota a DC omwe amafunikira torque yayikulu yokhala ndi kulemera kochepa komanso kuphatikizika, mota ya 4-pole ingakhale chisankho chabwino kwambiri.Ma motors a 4-pole atha kukhala ofanana ndi ma motors 2-pole, koma amatha kupanga torque yambiri.Ndikofunika kuzindikira kuti 4-pole motor ilinso yamphamvu kuposa 2-pole mota ya kukula kofananira, kutanthauza kuti imasunga liwiro lake molondola kwambiri ikagwiritsidwa ntchito.
Kuchuluka kwa mitengo kumatanthawuza kuchuluka kwa mapeya a maginito okhazikika mu mota.Injini yokhala ndi mapole awiri ili ndi maginito moyang'ana kumpoto ndi kumwera.Pamene magetsi akugwiritsidwa ntchito pakati pa mizati, mphamvu ya maginito imapangidwa, yomwe imachititsa kuti rotor ikhale yozungulira.Kukonzekera kwamagalimoto kumayambiranso 4-pole, kuphatikiza ma mizati awiri, mpaka mapangidwe amitengo yambiri, kuphatikiza mpaka mizati 12.
Kuchuluka kwa mizati ndi gawo lofunikira pamapangidwe a mota chifukwa zimakhudza liwiro ndi ma torque a mota.Kutsika kwa mitengo yamitengo, kumapangitsanso kuthamanga kwa injini.Izi zili choncho chifukwa kusinthasintha kulikonse kwa makina a rotor kumadalira kukwaniritsidwa kwa maginito a maginito pamitengo iliyonse.Mapeyala ochulukirapo a maginito okhazikika omwe injini imakhala nawo, m'pamenenso mafunde osangalatsa amafunikira, zomwe zikutanthauza kuti ikamatenga nthawi yayitali kuti rotor imalize kuzungulira kwa 360 °.Liwiro limagawidwa ndi kuchuluka kwa ma pole awiri pafupipafupi, motero potengera mota ya 2-pole pa 10,000 rpm, mota ya 4-pole ipanga 5000 rpm, mota yamapole asanu ndi imodzi imathamanga pa 3300 rpm, etc. ..
Ma motors akulu amatha kupanga torque yambiri mosasamala kuchuluka kwa mitengo.Komabe, kuchulukitsa kuchuluka kwa mitengo kumatha kupanga torque yochulukirapo kuposa injini yofanana.Pankhani ya mota ya 4-pole, torque yake imachulukitsidwa kwambiri ndi kapangidwe kake kakang'ono kanjira kakang'ono ka maginito kobwerera kusiya malo ochulukirapo a mapeyala awiri amitengo ya maginito okhazikika, ndipo pankhani ya ma maxon motors, mapindikidwe ake opindika opindika.
Ngakhale mota ya 4-pole imatha kutengera mawonekedwe a 2-pole, ziyenera kuzindikirika kuti kuwonjezereka kwamitengo kuchokera pa 6 mpaka 12 kumatanthauza kuti kukula ndi kulemera kwa chimango kuyenera kuchulukitsidwa mpaka sungani chingwe chowonjezera chamkuwa., chitsulo ndi maginito safunika.
Mphamvu ya mota nthawi zambiri imatsimikiziridwa ndi liwiro la torque gradient, kutanthauza kuti mota yamphamvu kwambiri imatha kugwira liwilo mwamphamvu ikagwiritsidwa ntchito.Kuthamanga kwa torque kumayesedwa ndi kuchepa kwa liwiro pa 1 mNm ya katundu.Manambala otsika komanso magiredi ocheperako amatanthauza kuti injiniyo imatha kuyendetsa liwiro lake ponyamula.
Galimoto yamphamvu kwambiri imatheka chifukwa cha mapangidwe omwewo omwe amathandizanso kuti akwaniritse ma torque apamwamba, monga ma windings ochulukirapo komanso kugwiritsa ntchito zida zabwino kwambiri popanga.Choncho galimoto ya 4-pole ndiyodalirika kwambiri kuposa 2-pole motor yofanana.
Mwachitsanzo, 4-pole maxon motor yokhala ndi mainchesi 22 mm ili ndi liwiro komanso torque gradient ya 19.4 rpm/mNm, zomwe zikutanthauza kuti imangotaya 19.4 rpm pa 1 mNm iliyonse yomwe imagwiritsidwa ntchito, pomwe 2- maxon pole motor ya Kukula komweko kuli ndi liwiro komanso torque gradient ya 110 rpm./mnm.Sikuti opanga magalimoto onse amakwaniritsa kapangidwe ka maxon ndi zofunikira zakuthupi, kotero mitundu ina ya ma motor 2-pole imatha kukhala ndi liwiro lalikulu komanso ma torque gradient, kuwonetsa mota yocheperako.
Mapulogalamu apamlengalenga amapindula ndi kuwonjezereka kwamphamvu ndi kulemera kwa ma motors 4-pole.Makhalidwewa amafunikiranso pazida zamagetsi zogwiritsidwa ntchito pamanja, zomwe nthawi zambiri zimafuna torque yochulukirapo kuposa injini ya 2-pole ingapereke, komabe imakhala yopepuka komanso yaying'ono.
Kuchita kwa mota ya 4-pole ndikofunikiranso kwa opanga ma loboti am'manja.Maloboti oyenda pamawilo kapena otsatiridwa amayenera kuthana ndi mtunda woyipa, zopinga ndi malo otsetsereka poyang'ana mapaipi amafuta ndi gasi kapena kufunafuna anthu omwe akhudzidwa ndi chivomezi.Ma motors a 4-pole amapereka torque ndi mphamvu yofunikira kuti athe kuthana ndi katunduyu, kuthandiza opanga maloboti am'manja kupanga mapangidwe opepuka komanso opepuka.
Kukula kwakung'ono, kuphatikizidwa ndi liwiro lotsika komanso ma torque gradients, ndikofunikiranso kuwongolera bwino mumakampani amafuta ndi gasi.Pogwiritsa ntchito izi, ma compact 2-pole motors alibe mphamvu zokwanira ndipo ma motors ambiri ndiakulu kwambiri kuti sangayang'anire pang'ono, motero Maxon adapanga mota ya 32mm 4-pole.
Mapulogalamu ambiri oyenera ma motors 4-pole amapezeka m'malo ovuta kwambiri kapena m'malo omwe amafunikira kuti athe kugwira ntchito kutentha kwambiri, kuthamanga kwambiri komanso kugwedezeka.Mwachitsanzo, ma motors owongolera bwino amatha kugwira ntchito pa kutentha kopitilira 200 ° C, pomwe ma motors oyikidwa m'magalimoto oyenda pansi pamadzi (AUVs) amakhala m'matangi odzaza mafuta.Ndi mawonekedwe owonjezera monga manja ndi matekinoloje opititsa patsogolo kutentha, ma compact 4-pole motors amatha kupirira zovuta zogwirira ntchito kwa nthawi yayitali.
Ngakhale kutsimikizika kwamagalimoto ndikofunikira, kapangidwe ka makina onse oyendetsa, kuphatikiza ma gearbox, encoder, drive and control, akuyenera kuganiziridwa kuti akwaniritse ntchitoyo.Kuphatikiza pa kufunsira zamagalimoto, mainjiniya a maxon amathanso kugwira ntchito ndi magulu achitukuko a OEM kuti apange makina oyendetsa athunthu ogwiritsira ntchito.
maxon ndiwotsogola wotsogola wamakina apamwamba kwambiri a brushed ndi brushless DC servo motors ndi zoyendetsa.Ma motors awa amachokera ku 4mm mpaka 90mm ndipo amapezeka mpaka 500W.Timaphatikiza zowongolera zamagalimoto, zida ndi DC kukhala makina oyendetsa anzeru kwambiri omwe amatha kusinthidwa kuti akwaniritse zosowa za makasitomala athu.
Zolemba zabwino kwambiri za 2022. Fakitale yayikulu kwambiri padziko lonse lapansi ya pasitala ikuwonetsa ma robotiki ophatikizika komanso kugawa kosatha.
