Sei asynchronous michina uye tega navo

Chikonzero kuti asynchronous michina inoshandiswa nevakawanda, ndiyo pakururama yokugadzirwa kwawo, akavimbika uye manufacturability. The applicability matatu-danho uye chete-danho network, zvakawanda mukwaniso, nyore kuchinja kutungamirirwa kutenderera - izvi zvose zvinoita kuti kushaika sezvo anodzinga zvakasiyana-siyana mano, kusanganisira michina uye kuverenga nehurongwa.

A chinokosha zvinobatsira zvinowanikwa asynchronous michina, ndiko yavo yakakwirira pamwero kunyatsoshanda.

Rakajairika Motors - kilowatt, kushanda kwavo rakafara chaizvo, anenge ose maindasitiri zvebhizimisi, ivo vanoumba guru chikamu nemotokari dzakabatana.

Zita asynchronous yemagetsi michina vatopiwa nokuda kwavo chisina kutsetseka velocity kunobva zvokuimba mutoro pamusoro nomubato. The kumusoro ari kurwisa torque, saka izvozvo rotates zvishoma nezvishoma. The lag chisina kutsetseka velocity pamusoro rotor kubva rotational kumhanya remagineti kunotangira kuitika ruchiyerera napakati stator windings, anonzi pitikoti. It rinowanikwa, sezvo mutemo, sezvo hama ukoshi:

S = (ωn-ωp) / ωn

apo:

ωn - remagineti rotational akurumidze, rev / Maminitsi;..

ωp - rotor akurumidze, rev / Maminitsi ..

Hama tsika mutoro pamusoro zvishoma nezvishoma mumatope mugodhi kuratidzwa zvikurukuru pakuti kwadzinoita kuti idling S zvachose razero.

The mudziyo asynchronous muchina kwakafanana zvimwe electric motor kana jenareta. Pemvura stator chomukati anopiwa chaizvo grooves, iyo iri ichitenderera (panyaya-danho matatu nemushonga, uye nokuda chete-danho Motors - maviri). The rotor zvakare nyore, nechivako kwayo chakafanana tsindi keji, uye shorted windings kana kuonana zvindori.

Kana munhu tsindi-keji rotor nokuda inductive pamotokari kubva kuitika mune stator windings ari rotor electromotive simba rikauya maererano rworudyi mutemo. Zvadaro zvinhu zvose nyore: mapuranga maviri, izvo zvinopfuura magetsi, vanotanga kutaura nemumwe, uye pane torque.

Asynchronous muchina, izvo rotor inopiwa ne kuonana marin'i ushande kunyange nyore simba kuti kutenderera ichitenderera uchaguta zvakananga kuburikidza kabhoni brushes. rotors yakadaro inonzi danho.

Single-danho induction Motors vane windings maviri, uye kutanga kushanda, nokuti generating chikuru torque uye rotor chisina kutsetseka unwinding kusvika uchishandisa akurumidze. Motors aya anoshandiswa uko-danho matatu samambure asipo Somuenzaniso, kudzinga kutenderera zvikamu veimba midziyo yemagetsi.

Kuwedzera injini induction ndivo vakomana chinangwa michina, emagetsi. mudziyo ravo substantially yakafanana. To mbiri yeRussian magetsi engineering, tinogona kutaura nechivimbo pamusoro kukoshesa munyika yedu mumunda dzemagetsi Motors iri mhando. MO Dolivo-Dobrovolsky shure muna 1889-chokutambudzika matatu munyika simba akatanga kushanda uye akawana kutenderera remagineti. Modern asynchronous michina regai kwakasiyana yomuzana danho matatu Motors of Russian muvambi guru uye musayendisiti.
