Kuvhurwa uye kuvhara kwemachira emagetsi akangwara kunoenderana nekutenderera kwemamicro motors kuti uwane. Mamwe maketeni emagetsi emagetsi anoshandisa AC mota, asi nekufambira mberi kwehunyanzvi, micro DC mota dzakaiswa zvakanyanya kumhando dzakasiyana dzemagetsi maketeni zvigadzirwa. Saka, ndezvipi zvakanakira DC mota dzinoshandiswa mumaketeni emagetsi? Ndedzipi nzira dzakajairika dzekudzora kumhanya? Maketeni emagetsi anoshandisa micro DC motors ane magiya anoderedza, ane zvakanakira torque yakakwira uye yakaderera kumhanya, uye anogona kutyaira akasiyana marudzi emaketeni zvichienderana neakasiyana ekuderedza reyesheni. Yakajairika micro DC mota mumaketeni emagetsi mabhurashi mota uye brushless mota. Iwo mabhenefiti makuru eakabhurasheswa DC mota anosanganisira yakakwira yekutanga torque, kushanda kwakatsetseka, mutengo wakaderera, uye nyore kukurumidza kudzora; brushless DC motors ine zvakanakira hupenyu hurefu uye yakaderera ruzha, asi mutengo wavo wakakwira, uye kutonga kwakanyanya kuoma. Nokudaro, kune akawanda maketeni emagetsi pamusika anoshandisa brushed motors.
Yakasiyana Yekumhanyisa Kudzora Nzira dzeMicro DC Motors muMagetsi Maketeni
1. Kana kukurumidza kwechidzitiro chemagetsi DC motokari inogadziriswa nekuderedza simba rekudzivirira, mhepo yekudzivirira inoda kugadziriswa kwemagetsi emagetsi eDC, uye kupikisa kwechikwata chechikwata uye mhepo yekukurudzira inofanira kuva duku sezvinobvira. Kana iyo voltage yadzikiswa, kumhanya kwechidzitiro chemagetsi DC mota inodererawo zvinoenderana.
2. Speed kudzora neyakatevedzana kuramba mune armature dunhu reDC mota, iyo yakakura nhevedzano kuramba, iyo ine kushaya simba maitiro emuchina, uye zvakanyanya kusagadzikana kumhanya. Pakumhanya kwakaderera, nekuda kweiyo yakakura nhevedzano kuramba, simba rakawanda rinorasika, uye simba rakaderera. Iyo yekumhanyisa control range inobatwa nemutoro, kureva kuti, mitoro yakasiyana inoguma neyakasiyana nhanho yekudzora mhedzisiro.
3. Isina simba remagineti kumhanya kudzora, kudzivirira magineti emagetsi keteni yeDC mota kubva pakuzara zvakanyanya, kudzora kumhanya kunofanirwa kushandisa isina simba magineti pachinzvimbo chesimba remagineti. Iyo armature voltage yeDC mota inochengetwa pamutengo wakayerwa, uye iyo inoteedzana kuramba mune armature wedunhu inoderedzwa. Iyo yekuwedzeredza yazvino uye magineti flux inoderedzwa nekuwedzera iyo yekuwedzeredza yedunhu kuramba Rf, nekudaro ichiwedzera kumhanya kweyemagetsi keteni DC mota uye kupfavisa hunhu hwemagetsi. Kana iyo kumhanya ichikwira, kana torque yemutoro ikaramba iri pamutengo wakayerwa, simba remota rinopfuura iro rakayerwa simba, zvichiita kuti mota ishande yakawandisa, isingabvumirwe. Naizvozvo, kana isina simba remagineti ikagadziriswa, torque yemutoro inodzikira zvinoenderana nekuwedzera kwekumhanya kwemota. Iyi inogara iine simba rekukurumidza kudzora. Kuti udzivise kutenderera kwemota rotor kubva pakubviswa uye kukuvadzwa nekuda kwesimba rakawandisa recentrifugal, kutarisisa kunofanirwa kubhadharwa kusapfuudza iyo inobvumidzwa muganhu weDC mota kumhanya kana uchishandisa isina simba remagineti kumhanya kudzora.
4. Mukukurumidza kudzora sisitimu yemagetsi keteni DC mota, iyo iri nyore nzira yekupedzisa kukurumidza kutonga ndeye kushandura kupikisa mubato rezvombo. Iyi nzira ndiyo yakapfava uye ine mutengo wakaderera, uye inoshanda zvakanyanya pakukurumidza kutonga kwemaketeni emagetsi.
Aya ndiwo maitiro uye kukurumidza kudzora nzira dzeDC motors dzinoshandiswa mumaketeni emagetsi.
