[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 oyinsalela, abe mancane owamanje, futhi anciphise isivinini. Lokhu kulungile. Kusukela 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 wenkundla kazibuthe, kuzobaluleka. 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 kuzokwenzeka nakanjani. Ngaphezu kwalokho, Ingcina engaphezulu kwensimbi kazibuthe esetshenziswa ngesandla futhi enendawo encane yokumboza iglue isabalaliswa ngokungalingani, okuholela ekunamatheleni okubi, futhi insimbi kazibuthe ingase iwe ngesikhathi sokusetshenziswa kamuva.
