1, AC asynchronous motor

AC asynchronous motor ke enjene ea motlakase ea AC e etellang pele, e sebelisoang haholo ho li-fan tsa motlakase, lihatsetsi, mechini e hlatsoang, li-air conditioner, li-dryer, li-vacuum cleaners, li-hoods, lijana tse hlatsoang lijana, metjhini e rokang ea motlakase, mechini e lokisang lijo le lisebelisoa tse ling tsa lapeng, joalo ka ha. hammoho le lisebelisoa tse fapaneng tsa motlakase le lisebelisoa tse nyane tsa motlakase.

AC asynchronous motor e arotsoe ka enjene ea induction le AC commutator motor.Enjene ea induction e arotsoe ka karolo e le 'ngoe ea asynchronous motor, AC / DC motor le repulsion motor.

Lebelo la enjene (lebelo la rotor) le ka tlase ho lebelo la matla a khoheli a potolohang, kahoo e bitsoa asynchronous motor.Ha e le hantle e tšoana le motor induction.S = (ns-n) / NS.S ke lebelo la ho thella,

NS ke lebelo la matla a khoheli 'me N ke lebelo la rotor.

Molao-motheo oa mantlha:

1. Ha motlakase oa asynchronous oa mekhahlelo e meraro o amana le motlakase oa AC oa mekhahlelo e meraro, maqhubu a mararo a stator a phalla ka matla a magnetomotive a mekhahlelo e meraro (stator rotating magnetomotive force) e hlahisoang ke mekhahlelo e meraro ea symmetrical hona joale 'me e hlahisa. matla a khoheli a potolohang.

2. Matla a khoheli a potolohang a na le motsamao oa ho itšeha o amanang le mokhanni oa rotor.Ho latela molao-motheo oa induction ea electromagnetic, mokhanni oa rotor o hlahisa matla a elektromotive le hona joale.

3. Ho ea ka molao oa matla a motlakase, mochine oa hona joale oa rotor o angoa ke matla a motlakase sebakeng sa khoheli ho etsa torque ea motlakase le ho khanna rotor ho potoloha.Ha ho e-na le mojaro oa mochine holim'a shaft ea motlakase, e tla hlahisa matla a mochine ka ntle.

Enjene ea Asynchronous ke mofuta oa enjene ea AC, 'me karo-karolelano ea lebelo le tlas'a mojaro ho ea makhetlo a marang-rang a marang-rang a hokahaneng ha e fetohe.E boetse e fetoha le boholo ba mojaro.Ha torque ea mojaro e le kholoanyane, lebelo la rotor le tlase.Enjene ea Asynchronous e kenyelletsa enjene ea induction, enjene e feptjoang habeli le enjene ea AC commutator.Enjene ea induction ke eona e sebelisoang haholo.Ka kakaretso e ka bitsoa asynchronous motor ntle le ho baka ho se utloisisane kapa pherekano.

Maqhubu a stator a motlakase a tloaelehileng a asynchronous a hokahane le marang-rang a matla a AC, 'me maqhubu a rotor ha a hloke ho hokahanngoa le mehloli e meng ea matla.Ka hona, e na le melemo ea sebopeho se bonolo, tlhahiso e bonolo, tšebeliso le tlhokomelo, ts'ebetso e tšepahalang, boleng bo tlase le theko e tlase.Enjene ea Asynchronous e na le ts'ebetso e phahameng ea ts'ebetso le litšobotsi tse ntle tsa ho sebetsa.E matha ka lebelo le sa khaotseng ho tloha ho se nang mojaro ho isa mojaro o felletseng, o ka fihlelang litlhoko tsa phetisetso ea mechini e mengata ea tlhahiso ea indasteri le temo.Li-motor tsa Asynchronous le tsona li bonolo ho hlahisa mefuta e fapaneng ea ts'ireletso ho fihlela litlhoko tsa maemo a fapaneng a tikoloho.Ha enjene ea asynchronous e ntse e sebetsa, matla a hlasimollang a ts'oarehang a tlameha ho kenngoa ho grid ea matla ho senya matla a marang-rang a matla.Ka hona, li-motors tsa synchronous li atisa ho sebelisoa ho khanna lisebelisoa tsa mochine tse matla le tse tlaase tse kang li-mill le li-compressor.Hobane lebelo la enjene ea asynchronous le na le kamano e itseng e thellang le lebelo la matla a khoheli a potolohang, ts'ebetso ea eona ea taolo ea lebelo ha e ntle (ntle le koloi ea AC commutator).Enjene ea DC e na le chelete e ngata ebile e bonolo bakeng sa mochini oa lipalangoang, leloala le thellang, sesebelisoa sa mochini o moholo, mochini o hatisang le oa ho daea le oa ho etsa pampiri o hlokang mefuta e mengata ea taolo ea lebelo le boreleli.Leha ho le joalo, ka nts'etsopele ea lisebelisoa tsa elektroniki tse matla haholo le sistimi ea taolo ea lebelo la AC, ts'ebetso ea taolo ea lebelo le moruo oa asynchronous motor e loketseng taolo ea lebelo le pharalletseng li bapisoa le tsa DC motor.
