Kusiyana Pakati pa Ma Sensored ndi Sensorless Motors: Zinthu Zofunika Kwambiri ndi Ubale wa Dalaivala
Ma mota opangidwa ndi masensa ndi opanda masensa amasiyana momwe amazindikira malo a rotor, zomwe zimakhudza momwe amagwirira ntchito ndi dalaivala wa mota, zomwe zimakhudza magwiridwe antchito ndi kuyenerera kwa ntchito. Kusankha pakati pa mitundu iwiriyi kumagwirizana kwambiri ndi momwe amagwirira ntchito ndi oyendetsa magalimoto kuti azilamulira liwiro ndi mphamvu.
Magalimoto Osensa
Ma mota opangidwa ndi sensor amagwiritsa ntchito zipangizo monga Hall effect sensors kuti aziyang'anira malo a rotor nthawi yeniyeni. Masensawa amatumiza mayankho mosalekeza kwa dalaivala wa mota, zomwe zimathandiza kuwongolera bwino nthawi ndi gawo la mphamvu ya mota. Mu dongosololi, dalaivala amadalira kwambiri chidziwitso kuchokera ku masensa kuti asinthe momwe magetsi amayendera, kuonetsetsa kuti ntchito ikuyenda bwino, makamaka panthawi yothamanga pang'ono kapena yoyima. Izi zimapangitsa kuti ma mota opangidwa ndi sensor akhale abwino kwambiri pakugwiritsa ntchito komwe kuwongolera kolondola ndikofunikira, monga ma robotic, magalimoto amagetsi, ndi makina a CNC.
Chifukwa chakuti dalaivala wa mota mu makina opangidwa ndi masensa amalandira deta yeniyeni yokhudza malo a rotor, imatha kusintha momwe injiniyo imagwirira ntchito nthawi yeniyeni, zomwe zimapangitsa kuti ikhale yolamulira kwambiri liwiro ndi mphamvu. Ubwino uwu umawonekera kwambiri pa liwiro lotsika, pomwe motayo iyenera kugwira ntchito bwino popanda kuyima. Muzochitika izi, ma sensored motors amachita bwino kwambiri chifukwa dalaivala amatha kukonza magwiridwe antchito a motayo nthawi zonse kutengera momwe sensor imayankhira.
Komabe, kuphatikizana kwa masensa ndi dalaivala wa injini kumeneku kumawonjezera zovuta ndi mtengo wa makina. Ma sensor motors amafunikira mawaya owonjezera ndi zigawo zina, zomwe sizimangowonjezera ndalama zokha komanso zimawonjezera chiopsezo cha kulephera, makamaka m'malo ovuta. Fumbi, chinyezi, kapena kutentha kwambiri zimatha kuchepetsa magwiridwe antchito a masensa, zomwe zingayambitse mayankho olakwika komanso kusokoneza luso la dalaivala lowongolera injini bwino.
Magalimoto Opanda Masensa
Koma ma mota opanda masensa sadalira masensa enieni kuti adziwe malo a rotor. M'malo mwake, amagwiritsa ntchito mphamvu ya kumbuyo kwa electromotive (EMF) yopangidwa pamene injini ikuzungulira kuti iyerekeze malo a rotor. Woyendetsa galimoto mu dongosololi ali ndi udindo wozindikira ndikutanthauzira chizindikiro cha kumbuyo kwa EMF, chomwe chimakhala champhamvu pamene injini ikuwonjezeka liwiro. Njirayi imapangitsa kuti dongosololi likhale losavuta pochotsa kufunikira kwa masensa enieni ndi mawaya owonjezera, kuchepetsa mtengo ndikuwonjezera kulimba m'malo ovuta.
Mu makina opanda masensa, dalaivala wa mota amachita gawo lofunika kwambiri chifukwa ayenera kuwerengera malo a rotor popanda mayankho operekedwa mwachindunji ndi masensa. Pamene liwiro likukwera, dalaivala amatha kuwongolera mota molondola pogwiritsa ntchito zizindikiro zamphamvu za EMF kumbuyo. Ma mota opanda masensa nthawi zambiri amagwira ntchito bwino kwambiri pa liwiro lalikulu, zomwe zimapangitsa kuti akhale osankhidwa otchuka m'mapulogalamu monga mafani, zida zamagetsi, ndi machitidwe ena othamanga kwambiri komwe kulondola pa liwiro lotsika sikofunikira kwenikweni.
Vuto la ma mota opanda masensa ndilakuti sagwira bwino ntchito pa liwiro lotsika. Dalaivala wa mota amavutika kuyerekeza malo a rotor pamene chizindikiro chakumbuyo cha EMF chili chofooka, zomwe zimapangitsa kuti injini isakhazikike, isinthe, kapena ikhale ndi vuto poyambitsa. Mu ntchito zomwe zimafuna kuti injini igwire bwino ntchito mofulumira, malire awa akhoza kukhala vuto lalikulu, ndichifukwa chake ma mota opanda masensa sagwiritsidwa ntchito m'makina omwe amafuna kuwongolera kolondola pa liwiro lililonse.
Mapeto
Ubale pakati pa ma mota ndi oyendetsa ndi wofunikira kwambiri pa kusiyana pakati pa ma mota opangidwa ndi masensa ndi opanda masensa. Ma mota opangidwa ndi masensa amadalira mayankho a nthawi yeniyeni kuchokera ku masensa kupita kwa dalaivala wa mota, kupereka ulamuliro wolondola, makamaka pa liwiro lotsika, koma pamtengo wokwera. Ma mota opangidwa ndi masensa, ngakhale kuti ndi osavuta komanso otsika mtengo, amadalira kwambiri luso la dalaivala lotha kutanthauzira zizindikiro za EMF kumbuyo, zomwe zimagwira ntchito bwino pa liwiro lokwera koma zimavuta pa liwiro lotsika. Kusankha pakati pa njira ziwirizi kumadalira zofunikira zenizeni za magwiridwe antchito a pulogalamuyi, bajeti, ndi momwe imagwirira ntchito.
