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, mechini 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.

Enjene ea AC asynchronous e arotsoe ka enjene ea induction le enjene ea AC commutator.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 enjene ea 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 hokahane le motlakase oa AC oa mekhahlelo e meraro, maqhubu a mararo a stator a phalla ka matla a mararo a matla a magnetomotive (stator rotating magnetomotive force) a hlahisoang ke mekhahlelo e meraro ea symmetrical hona joale le ho 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 ea ka molao-motheo oa induction ea electromagnetic, conductor ea rotor e hlahisa matla a motlakase a susumelitsoeng le a 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 a 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 moea oa rotor ha o 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.Asynchronous motor 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 sebetsa, matla a hlasimollang a ts'oarehang a tlameha ho monngoa ho tsoa ho marang-rang a 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 mechini ea 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 tsa matla a phahameng 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.
