Kuvhurwa nekuvharwa kwemaketeni emagetsi akangwara kunoenderana nekutenderera kwema micro motors kuti zvibudirire. Mamwe ma electric curtain motors anoshandisa ma AC motors, asi nekufambira mberi kwetekinoroji, ma micro DC motors ave achishandiswa zvakanyanya kumhando dzakasiyana dzezvigadzirwa zve electric curtain. Saka, ndeapi mabhenefiti ema DC motors anoshandiswa muma electric curtains? Ndedzipi nzira dzakajairika dzekudzora kumhanya? Maketeni emagetsi anoshandisa ma micro DC motors ane gear reducers, ane mabhenefiti e high torque uye low speed, uye anogona kutyaira marudzi akasiyana emaketeni zvichienderana ne reduction ratios dzakasiyana. Ma micro DC motors akajairika muma electric curtains i brushed motors nema brushless motors. Mabhenefiti makuru ema brushed DC motors anosanganisira high starting torque, soft operation, low cost, uye speed control iri nyore; ma DC motors asina brush ane mabhenefiti ehupenyu hurefu uye ruzha rushoma, asi mutengo wawo wakakwira, uye kutonga kwakaoma. Saka, kune akawanda ma electric curtains pamusika anoshandisa ma brushed motors.
Nzira Dzakasiyana Dzekudzora Kumhanya Kwemota DzeMicro DC Mumaketeni Emagetsi
1. Kana kumhanya kwemota yeDC curtain yemagetsi kuchigadziriswa nekuderedza voltage yearmature, circuit yearmature inoda simba reDC rinodzorwa, uye resistance yecircuit yearmature necircuit yeexcitation inofanira kunge iri diki sezvinobvira. Kana voltage yadzikira, kumhanya kwemota yeDC curtain yemagetsi kuchadzikirawo saizvozvo.
2. Kudzora kumhanya nekudzivirira kwakatevedzana mudunhu remagetsi remota yeDC, kudzivirira kwakakura, hunhu hwemakanika husina kusimba, uye kumhanya kwacho kunowedzera kusagadzikana. Pakumhanya kwakaderera, nekuda kwekudzivirira kwakakura, simba rakawanda rinorasika, uye simba rakaderera. Kudzora kumhanya kunokanganiswa nemutoro, kureva kuti, mitoro yakasiyana inokonzera mhedzisiro dzakasiyana dzekudzora kumhanya.
3. Kudzora kumhanya kwemagnetic kusina kusimba, kudzivirira kuti magnetic circuit yemagetsi eDC curtain motor isanyanya kuzara, speed control inofanira kushandisa weak magnetism panzvimbo pe strong magnetism. Armature voltage yeDC motor inochengetwa pamutengo wakarongwa, uye series resistance mu armature circuit inoderedzwa. Excitation current uye magnetic flux zvinoderedzwa nekuwedzera excitation circuit resistance Rf, nokudaro zvichiwedzera kumhanya kwemagetsi eDC curtain mota uye kunyorovesa hunhu hwemakanika. Kana speed yakwira, kana load torque ikaramba iri pamutengo wakarongwa, simba remota richapfuura rated power, zvichiita kuti mota ishande yakawandisa, izvo zvisingabvumirwe. Naizvozvo, kana weak magnetic speed ikagadziriswa, load torque ichaderera zvinoenderana nekuwedzera kwemota. Uku kudzora kumhanya kwesimba nguva dzose. Kudzivirira motor rotor kuti isaputswe uye ikuvadzwe nekuda kwesimba rakawandisa re centrifugal, kungwarira kunofanirwa kupihwa kuti kusapfuure muganho unobvumirwa weDC motor speed pakushandisa weak magnetic field speed control.
4. Munzira yekudzora kumhanya kwemota yemagetsi yeDC curtain, nzira iri nyore yekupedzisa kudzora kumhanya ndeyekushandura resistance mu armature circuit. Nzira iyi ndiyo iri nyore uye ine mutengo wakaderera, uye inoshanda zvikuru pakudzora kumhanya kwe machira emagetsi.
Aya ndiwo maitiro uye nzira dzekudzora kumhanya kwemamota eDC anoshandiswa mumaketeni emagetsi.
