Kufotokozera mwachidule za wokonda EC

Wokonda EC ndi chinthu chatsopano pamsika wama fan. Ndizosiyana ndi mafani ena a DC. Sizingagwiritse ntchito magetsi amagetsi a DC, komanso magetsi a AC. Voteji yochokera ku DC 12v, 24v, 48v, mpaka AC 110V, 380V ikhoza kukhala yachilengedwe, palibe chifukwa chowonjezera kutembenuka kwa inverter. Ma mota onse omwe ali ndi zero zamkati mwake ndi magetsi a DC, omangidwa mu DC kupita ku AC, mayankho ozungulira malo, AC yamagawo atatu, maginito okhazikika, ma mota ofananira.

Ubwino wa mafani a EC:

EC mota ndi DC yopanda brushless yokonza magalimoto okhala ndi module yolamulira yanzeru. Zimabwera ndi mawonekedwe a RS485, mawonekedwe a 0-10V otulutsa mawonekedwe, 4-20mA liwiro loyendetsa mawonekedwe, mawonekedwe a alamu opangira mawonekedwe ndi mawonekedwe aukapolo wa akapolo. Mankhwala ali ndi makhalidwe a nzeru mkulu, mphamvu zopulumutsa mkulu, dzuwa mkulu, moyo wautali, otsika kugwedera, phokoso otsika ndi ntchito mosalekeza ndipo mosadodometsedwa:

Njinga ya brushless DC yasinthiratu kapangidwe kake chifukwa chosonkhanitsa mphete ndi maburashi azisangalalo asiyidwa. Nthawi yomweyo, sikumangokhala kogwira ntchito kokha kwamagalimoto, koma kudalirika kwamakina oyendetsa galimoto kumalimbikitsidwa kwambiri, ndipo moyo wautumiki umakulitsidwa.

Nthawi yomweyo, kusiyana kwa maginito am'mlengalenga kumatha kukonzedwa bwino, ndipo cholozera cha mota chitha kukwaniritsa mapangidwe abwino kwambiri. Zomwe zimachitika ndichoti voliyumu yamagalimoto imachepetsedwa ndipo kulemera kwake kumachepa. Osati zokhazo, poyerekeza ndi ma motors ena, ilinso ndi magwiridwe antchito abwino kwambiri. Izi ndichifukwa choti: Choyamba, chifukwa chogwiritsa ntchito maginito okhazikika, mphamvu ya torque inertia, komanso mphamvu yamagalimoto imayendetsedwa bwino. Kudzera pakupanga koyenera, ma index monga mphindi ya inertia, magetsi ndi makina osintha nthawi amatha kuchepetsedwa kwambiri, popeza magawo akulu a magwiridwe antchito a servo asintha kwambiri. Kachiwiri, kapangidwe ka maginito amakono amakono osasunthika ndi amphumphu, ndipo kukakamira kwa maginito kosatha ndikokwera, chifukwa chake anti-armature reaction ndi anti-demagnetization luso lamagalimoto okhazikika limalimbikitsidwa kwambiri. Mphamvu zakusokoneza zimachepa kwambiri. Chachitatu, chifukwa maginito okhazikika ntchito m'malo malemeredwe magetsi, kamangidwe ka malemeredwe kumulowetsa ndi malemeredwe maginito yafupika, ndi magawo ambiri monga kamwazi kukondoweza, malemeredwe inductance, ndi malemeredwe panopa yafupika, potero mwachindunji kuchepetsa zosintha controllable kapena magawo. Kutengera ndi zomwe tafotokozazi, titha kunena kuti maginito okhazikika ali ndi mayendedwe abwino kwambiri.
