[Ukwabelana Ngolwazi] Kungani izigxobo zikazibuthe ze-DC ezihlala njalo zisebenzisa omazibuthe abangamanxande?

I-exciter eyisiza kazibuthe unomphela iwuhlobo olusha lwe-rotor yangaphandle DC kazibuthe motor unomphela.Indandatho yayo yokuklinya ejikelezayo ilenga ngqo ekujuleni ku-shaft.Kunezigxobo kazibuthe ezingama-20 eringini.I-pole ngayinye inesicathulo se-pole esibalulekile.Umzimba wesigxobo wakhiwe izingcezu ezintathu eziwunxande.Yakhiwe ngensimbi kazibuthe futhi ihlanganiswe ibe iyonke nge-"914" glue.Umzimba wesigxobo usongwe futhi uqiniswe ngamaribhoni engilazi angena-latitude ukuze kwakheke umkhono ovikelayo.Isigxobo ngasinye nesicathulo se-pole zenziwe ngezingcezu ezimbili zebalainsimbi encane.

Kumotho kazibuthe we-DC unomphela, lapho amanye amapharamitha engashintshile, ayanda uzibuthe osalayo, abe mancane owamanje, futhi ijubane liyancipha.Lokhu kulungile.Kulokhu, ungakwazi ukuhlaziya ngokwakho ukuthi iyiphi imagnethi yama-prototypes akho amabili angcono.I-magnetism eyinsalela inkulu.Ngokuqondene nesimiso, lapho amanye amapharamitha ehlala engashintshile, ukuphakama kukazibuthe osalayo, kukhulu ukugeleza kazibuthe kwesigxobo ngasinye senjini.Ngokwefomula yesivinini ye-DC motor n=(U-IR)/CeΦ≈U/CeΦ, ingaba kakhulu Kulula ukuphetha ngokuthi u-Φ omkhulu, ijubane liphansi.Ijubane eliphansi, kuncane ukulahlekelwa okungalayishiwe, kanye nokuncane kwamandla amanje ongalayishi.

I-torque ye-rotor ekhiyiwe ye-DC unomphela uzibuthe motor ihlobene nobukhulu bukazibuthe namandla wenkundla kazibuthe.Uma ukushuba kungashintsha amandla kazibuthe, kuzoba okufanelekile.Ngesikhathi sokuhlanganisa uzibuthe wemoto kazibuthe oshumekiwe unomphela, uma usebenzisa iglue ebusweni bukazibuthe kwenza kube nzima ku-opharetha ukubamba umazibuthe.Ngesikhathi esifanayo, ngenxa yokungapheleli kobuchwepheshe obukhona lapho ufaka uzibuthe ku-slot, ukungqubuzana nodonga lwe-slot kuyokwenzeka nakanjani.Ngaphezu kwalokho, Iglu engaphezulu kwensimbi kazibuthe esetshenziswa ngesandla futhi enendawo encane yokumboza iglue isabalaliswa ngokungalingani, okuholela ekunamatheleni okubi, futhi insimbi kazibuthe ingase iwe ngesikhathi sokusetshenziswa kamuva.
