Kwiimoto zombane zanamhlanje ze-DC, indlela yokuvuselela esebenzisa i-DC yangoku ukuvelisa indawo enkulu ye-electromagnetic ebizwa ngokuba yi-excitation yangoku;Ukuba umazibuthe ongaguqukiyo usetyenziselwa ukubuyisela uvuselelo olukhoyo ukuvelisa ibala elikhulu lombane we-pole, olu hlobo lwemoto yombane lubizwa ngokuba yimagnethi yombane engenakubuyiseka.
I-Brushless inokufunyanwa kwiimeko ezininzi, ngoko ke isetyenziswa kakhulu kwiinjini zombane ezincinci kunye nezincinci.Xa usebenzisa unikezelo lwamandla ombane oguquguqukayo, injini yemagnethi engajikiyo inokuphinda isetyenziswe kwinkqubo yokuhanjiswa komgangatho.Ngohlaziyo oluqhubekayo kunye nokuphuculwa kwempumelelo yeemveliso zemagnethi ezingenakubuyela umva, iinjini zombane zemagnethi yexesha elide ziye zasetyenziswa kakhulu kwiinkalo ezahlukeneyo ezifana nezixhobo zosapho, izixhobo zonyango, izithuthi, inqwelomoya kunye nokhuseleko lwelizwe.
Icala elisezantsi lemoto yemagnethi yexesha elide kukuba, ukuba isetyenziswe ngokungafanelekanga, xa isebenza ngexabiso eliphantsi okanye kunye nobushushu obuncitshisiweyo, phantsi komsebenzi wempendulo ye-armature eyenziwe yi-inrush current, okanye phantsi kwe-resonance enzima yomatshini, inokuthi. ukudala umonakalo ongenakulungiseka.I-Demagnetization yenza ukuba ukusebenza kwemoto kube buthathaka okanye kungabi nanjongo.Ngeso sizathu, unyango olulodwa kufuneka luthatyathwe xa kusetyenziswa iimotor zemagnethi ezisisigxina.
Isingeniso
Ngo-1832, injineli yombane eselula yaseFransi uPixy yavelisa ngempumelelo ijenereyitha ejikelezayo yemagnethi ejikeleza umhlaba.
Kule generator, iPixie ifakele i-commutator yokuqala, eyathi yaguqula umjelo ojikelezayo owenziwe kwijenereyitha ukuya kwindawo ethe ngqo eyayifuneka kwimveliso yorhwebo ngelo xesha.Nangona kunjalo, uhlobo lwemagnethi olungenakuguquleka lukaPixie lweJenereyitha lunezinto ezimbini ezingeloncedo ezahlukeneyo.Okokuqala, izixhobo zayo zininzi ngokufanelekileyo, kwaye kunzima ukunyusa amandla ngokunyusa isantya.Okwesibini, amandla ayo ashukumisayo ngabasebenzi, okongeziweyo kunzima ukufumana amandla aphezulu akhoyo ngokunyusa izinga.
Kwangelo xesha kanye apho uPixie ephucule ijenereyitha yakhe yemagnethi yexesha elide, abanye abantu bafunda ngejenereyitha yemagnethi engajikiyo kwaye benza izinto ezintsha ezibalulekileyo.Ukusukela ngo-1833 ukuya kowe-1835, uSushston kunye noClark kunye nabanye bedibene baphuhlisa izixhobo ezitsha ezinje ngokujika icoil armature kunye nesakhelo semagnethi esimileyo.Isantya esijikayo.
Ukusukela ngoko, abantu baye batshintsha igajethi yamandla e-motive yejenereyitha, betshintsha isivumelwano kunye neshaft ejikelezayo, kunye nokutshintsha isandla ukuba siqhutywe yinjini yomphunga.Ngokwenza oku, isantya siphuculwe kakhulu, kwaye nomthamo wamandla ombane owenziweyo uye wanyuswa kakhulu.
Ngokwesiseko sobuchwephesha obu-2 obungasentla, obunye ubuchwephesha obumbalwa buye basetyenziswa.Malunga nowe-1844, eFransi, eJamani, eBritani nakwamanye amazwe, bekukho iijenereyitha ezinkulu ngoku kwaye zinzima ukubonelela amandla amatsha ombane wokuhlanjululwa, kunye nokubonelela ngamandla amatsha kraca koomatshini ngenjini yokuqala yombane.
Ukuzalwa kwejenereyitha yemagnethi esisigxina sisihlandlo sokuqala ukuba amandla oomatshini aguqulwe kumandla ashushu aguqulwa abe ngamandla ombane, ukuze abantu bafumane amandla amatsha anethemba elibanzi emva kwamandla obushushu.
