Permanent uzibuthe motor kanye nokusebenza kwayo

Permanent uzibuthe motor - Kutama ukunciphisa isisindo nobukhulu balezi umshini kagesi, ukuze kube lula oyiyo, ngcono nokwethenjelwa lula ukusetshenziswa. nenjini okunjalo kwenza kakhulu ukwandisa ukusebenza kahle (ukusebenza kahle). Ukusatshalaliswa ezinkulu wathola njengoba umshini undiza. Kulesi apharathasi, lo odonsa unomphela zenzelwe futhi ukusetshenziselwa ukudala ujikelezisa kazibuthe.

Okwamanje wasebenzisa okufana kuhlanganiswe: odonsa unomphela electromagnet, ikhoyili ka yiwo ogelezela njalo kagesi. Lokhu excitation kuhlanganiswe inikeza izici eziningi ezinhle: ukuthola edingekayo ukulungiswa voltage izici nesivinini ngenkathi ekunciphiseni amandla ukushayela, ukunciphisa ivolumu kohlelo kazibuthe (futhi, ngenxa yalokho, izindleko leli thuluzi, njengoba kuhlangene unomphela uzibuthe motor) ziqhathaniswa classical excitation kagesi uhlelo zokuvumelanisa umshini.

Kuze kube manje, ukusetshenziswa odonsa unomphela kungenzeka ngamandla idivayisi kuphela ezimbalwa kilovolt-amperes. Nokho, manje, ithuthukiswe odonsa unomphela ne ngokusebenza okuthuthukile, namandla umshini kancane kancane kwandisa.

motor evumelanisiwe njengoba unomphela uzibuthe motor isetshenziswa njengophawu motor noma generator ushayela ngqo amandla ezahlukene. Amadivayisi anjalo baye bathola isicelo nokusatshalaliswa ezimayini, sokuncibilikisa izitshalo, izitshalo amandla ezishisayo. Njengoba imoto zokuvumelanisa usebenza nge ezahlukene amandla esisheshayo, isetshenziswa amafriji, amaphampu kanye nezinye izindlela nge speed njalo. I motor kagesi nozibuthe unomphela esetshenziswa amadivaysi kanye namadivayisi ephansi amandla, okuyinto kudingeka esiqinile futhi enembile isivinini ukuqinisela. Lokhu okuzenzakalelayo tekucopha, elektrochasy, Izilawuli isofthiwe, nokuningi. Ngezinye iziteshi substations kukhona ugesi ekhethekile zokuvumelanisa ukuthi iveza idling kuphela amandla esisheshayo. Lo mbuso isetshenziselwa motors indlela futhi imishini zokuvumelanisa yalolu hlobo abizwa ngokuthi "compensators".

Isimiso yokusebenza womshini ezifana motor ne odonsa unomphela, futhi ikakhulu, motor zokuvumelanisa esekelwe nokuxhumana kazibuthe Rotor (ezithathekayo ingxenye) kanye stator (fixed okuyingxenye).

Ngenxa ezithakazelisayo futhi akukaqondwa ngokugcwele odonsa izakhiwo kanye kukhona okusunguliwe wavela kaningi okusekelwe kuzo. Ngokwesibonelo, omunye imibono obujwayelekile ukwakha kudivayisi efana esiphakade ezinyakazayo umshini ngaphandle ngophethiloli odonsa unomphela. Kusukela umbono wesayensi yemvelo ezinyakazayo esiphakade umshini yesimanje akunakwenzeka (ke kwakuyodingeka babe nekusebenta mkhulu kwelilodwa, futhi ubhekwa kube nengqondo), kodwa abaqambi emkhakheni amandla okunye ungalahli ithemba ngoba ukudalwa kanye nokuthuthukiswa ukutholakala enjalo.
