Kusiyanitsa Pakati pa Sensored ndi Sensorless Motors: Zofunika Kwambiri ndi Maubwenzi Oyendetsa
Ma motors a sensored ndi sensorless amasiyana momwe amawonera malo a rotor, zomwe zimakhudza kuyanjana kwawo ndi dalaivala wagalimoto, kukopa magwiridwe antchito ndi kuyenerera kwa ntchito. Kusankha pakati pa mitundu iwiriyi kumagwirizana kwambiri ndi momwe amagwirira ntchito ndi madalaivala oyendetsa galimoto kuti azitha kuyendetsa liwiro ndi torque.
Sensored Motors
Ma motors ozindikira amagwiritsa ntchito zida ngati masensa a Hall kuti aziwunika malo a rotor munthawi yeniyeni. Masensa awa amatumiza ndemanga mosalekeza kwa woyendetsa galimoto, zomwe zimalola kuwongolera nthawi ndi gawo la mphamvu ya injiniyo. Pokonzekera uku, dalaivala amadalira kwambiri chidziwitso chochokera ku masensa kuti asinthe kuperekera kwamakono, kuonetsetsa kuti ntchito ikuyenda bwino, makamaka panthawi yotsika kwambiri kapena yoyambira. Izi zimapangitsa ma motors ozindikira kukhala abwino kwa mapulogalamu omwe kuwongolera kolondola ndikofunikira, monga ma robotics, magalimoto amagetsi, ndi makina a CNC.
Chifukwa dalaivala wagalimoto mu kachitidwe ka masensa amalandira chidziwitso chenicheni cha malo a rotor, amatha kusintha magwiridwe antchito agalimoto munthawi yeniyeni, ndikuwongolera kwambiri liwiro ndi torque. Ubwinowu umawonekera kwambiri pama liwiro otsika, pomwe mota iyenera kugwira ntchito bwino popanda kuyimitsa. M'mikhalidwe iyi, ma sensor sensor amapambana chifukwa dalaivala amatha kuwongolera magwiridwe antchito agalimotoyo potengera mayankho a sensa.
Komabe, kuphatikiza kwapakatikati kwa masensa ndi oyendetsa galimoto kumawonjezera zovuta zamakina ndi mtengo. Ma motors okhudzidwa amafunikira mawaya owonjezera ndi zigawo zina, zomwe sizimangowonjezera ndalama komanso zimawonjezera chiopsezo cha zolephera, makamaka m'malo ovuta. Fumbi, chinyezi, kapena kutentha kwambiri kumatha kusokoneza magwiridwe antchito a masensa, zomwe zingayambitse kuyankha kolakwika komanso kusokoneza mphamvu ya dalaivala kuyendetsa bwino galimoto.
Sensorless Motors
Ma motors opanda mphamvu, kumbali ina, sadalira masensa akuthupi kuti azindikire malo a rotor. M'malo mwake, amagwiritsa ntchito mphamvu yakumbuyo ya electromotive (EMF) yomwe imapangidwa ngati ma spins a injini kuti ayerekeze malo a rotor. Woyendetsa galimoto m'dongosolo lino ali ndi udindo wozindikira ndi kutanthauzira chizindikiro cha EMF chakumbuyo, chomwe chimakhala champhamvu pamene galimoto ikuwonjezeka mofulumira. Njirayi imathandizira dongosololi pochotsa kufunikira kwa masensa amthupi ndi ma waya owonjezera, kuchepetsa mtengo ndikuwongolera kulimba m'malo ovuta.
M'makina opanda ma sensor, woyendetsa galimoto amatenga gawo lofunikira kwambiri chifukwa amayenera kuwerengera malo a rotor popanda mayankho achindunji operekedwa ndi masensa. Liwiro likamakula, dalaivala amatha kuwongolera injiniyo molondola pogwiritsa ntchito ma sign amphamvu a EMF. Ma motors opanda mphamvu nthawi zambiri amachita bwino kwambiri pa liwiro lapamwamba, zomwe zimawapangitsa kukhala odziwika bwino pamapulogalamu monga mafani, zida zamagetsi, ndi makina ena othamanga kwambiri komwe kulondola pa liwiro lotsika sikufunikira kwenikweni.
The drawback of sensorless motors ndi kusachita bwino kwawo pa liwiro lotsika. Woyendetsa galimoto amavutika kuti ayese malo a rotor pamene chizindikiro cha EMF chakumbuyo chili chofooka, zomwe zimayambitsa kusakhazikika, kugwedezeka, kapena vuto loyambitsa galimoto. M'mapulogalamu omwe amafunikira magwiridwe antchito ocheperako, izi zitha kukhala vuto lalikulu, chifukwa chake ma motorless sensors sagwiritsidwa ntchito pamakina omwe amafunikira kuwongolera moyenera pa liwiro lililonse.
Mapeto
Ubale pakati pa ma mota ndi madalaivala ndiwofunika kwambiri pakusiyana pakati pa ma sensors ndi sensorless motors. Ma motors ozindikira amadalira mayankho anthawi yeniyeni kuchokera ku masensa kupita kwa dalaivala, kupereka kuwongolera kolondola, makamaka pa liwiro lotsika, koma pamtengo wokwera. Ma motors opanda mphamvu, ngakhale kuti ndi osavuta komanso otsika mtengo, amadalira kwambiri kuthekera kwa dalaivala kutanthauzira ma sign a EMF kumbuyo, kuchita bwino pama liwiro apamwamba koma akulimbana ndi liwiro lotsika. Kusankha pakati pa zosankha ziwirizi kumatengera zomwe pulogalamuyo ikufuna, bajeti, ndi momwe amagwirira ntchito.
