DC makemikari: iyo maitiro ekushanda

Mishonga yemagetsi ndiyo mafaira ekushandura magetsi emagetsi kuva magetsi (uye pamwe chete). Kushanda kwe DC inoshandiswa pamutemo wekugadzirwa kwemagetsi.

Kazhinji, aya mashandisirwo anoshandiswa mumakambani ekugadzirisa zvinhu, zvakadai semakranes uye mabhechi. Chinhu chinokonzera kukanganisa kwejini ndiyo kuumbwa kwekhabhoni yemabhadhi paanounganidza kubva kune mabhurusi. Kuti urege kudzika zvakanyanya, zvinokosha kuti nguva nenguva uongorore uye uite basa rekudzivirira. Izvo zvakagadziriswa zveMDC zvinopesana nemasynchronous uye mafananidzi motokari.

Pakati pemapuranga achigadzira magnetic flux nguva dzose, pane anchore, yakagadzirwa nenzira yesimbi yesimbi. Munharaunda yaro inoshandiswa zvakatendwa nemutungamiri wemhangura, uye migumo yeitungamiri inobatana nemimirings, iyo inoparadzaniswa nedzimwe chikamu chemuchina - uyu ndiye muunganidzi uyo mabhurushesiti anoita. Izvo zvinobatanidzwa kune imwe kunze kwedunhu.

Sezvo simba rekugadzirisa magetsi rinowanikwa mumhepo, dhoni ye DC inotanga kutenderera kana munda uchitenderera.

Pamusana pekuti magnetic induction inoparadzaniswa zvisina kufanira pamusoro peyimbi yesimbi, kasi yeiyo yakagadzirwa EMF inobva pauwandu hwemazuva ano mumapapakati pakati pekutendeuka. Nokudaro, magnetic induction inowedzera pamapuranga, uye zero iri pakati pezvigadziriswe (pamutsara wenguva refu).

Apo zvigadzirwa zve DC zvinotenderera hafu yega-yega, vatungamiri vanoshandura maronda avo, nokuti vanowira pasi pesimba remapuranga akasiyana, naizvozvo hutungamiri hwe simba re electromotive hunochinjwa, uye kana EMF ichishandura munguva uye kutungamira, inofanira kugoverwa kune chinotengeswa. Kuti uwane nguva inowanikwa mukati memutunhu wekunze, muunganidzi anowirirana ne DC machine. Iko rudzi rwekuchinja. Fixed brushes, iyo yakabatanidzwa neketani yekunze, slide pedyo nemakona-makumbo akaiswa zvakasimba kune anchor.

Inotenderera, anchor inobata chete nebhurosi iyo, iyo iri pasi pevhu. Panguva iyo kutungamirirwa kwesimba re electromotive riri kuchinja, pane kuchinja kwezvindori, kureva, hapana kuchinja kune chinangwa che EMF chekunze kwese. Nokudaro, muunganidzi rudzi rwechigadziridzo harubvumiri ikozvino rakagadzirwa kuchinja.

Kuti usabvisa kutora kwe simba re electromotive, pane kutendeuka pachombo chinosungirirwa pazvikamu zviviri zvezvikwata zvekuunganidza. Kutendeuka kunoshandurwa kubva kune imwe kuenda kune imwe yenzira isingakoshi, izvi zvinobvumira kubhadhara zvipfeko muhu harmonics uye ikozvino inopinda mudunhu pasina kuputika.

Kana iyo DC inoshandisa iyo injini mode, saka, asi, iyo inoshandiswa kune mabhurusi. Nokudaro, kupfuura nepakati pevatori, mazuva ano anowanikwa mukushanduka, izvo zvinoumba magnetic field. Kuwirirana nemunda wemapuranga, zvigadziri zvinotanga kuchinja, zvisinei, panguva iyo mutungamiri wekushandura panguva yekufamba kwevatungamiri kuburikidza nepamberi yakatarisana inofanira kunge yakashanduka, muunganidzi achiri kuchinja polarity. Nokudaro, mutungamiri wezvino uye, maererano naizvozvo, magnetic field inoshanduka. Muchiitiko ichi, muunganidzi inverter, DC-to-AC mutaridzi .
