Nalane ea nts'etsopele ea theknoloji ea taolo ea makoloi a induction

Nalane ea likoloi tsa motlakase e qalile ka 1820, ha Hans Christian Oster a sibolla matla a khoheli a motlakase, mme selemo hamorao Michael Faraday o ile a sibolla ho potoloha ha motlakase mme a haha ​​​​mochine oa pele oa pele oa DC.Faraday o ile a sibolla induction ea motlakase ka 1831, empa e bile ka 1883 moo Tesla a ileng a qapa enjene ea induction (asynchronous).Kajeno, mefuta e ka sehloohong ea mechine ea motlakase e ntse e tšoana, DC, induction (asynchronous) le synchronous, tsohle tse thehiloeng likhopolong tse entsoeng le ho sibolloa ke Alstead, Faraday le Tesla lilemong tse lekholo tse fetileng.

Ho tloha ha ho qaptjoa enjene ea induction, e se e le eona enjene e sebelisoang haholo kajeno ka lebaka la melemo ea motor induction ho feta likoloi tse ling.Monyetla o ka sehloohong ke hore li-motors tsa induction ha li hloke khokahanyo ea motlakase pakeng tsa likarolo tse emeng le tse potolohang tsa enjene, ka hona, ha li hloke li-commutator tsa mochini (li-brushes) mme ke li-motors tsa mahala tsa tlhokomelo.Li-motors tsa induction li boetse li na le litšobotsi tsa boima bo bobebe, inertia e tlase, ts'ebetso e phahameng, le matla a boima a mangata.Ka lebaka leo, li theko e tlaase, li matla, 'me ha li hlōlehe ka lebelo le phahameng.Ho feta moo, enjene e ka sebetsa sebakeng se phatlohileng ntle le ho hlaba.

Ha ho nahanoa ka melemo eohle e kaholimo, li-motors tsa induction li nkuoa e le li-converter tse phethahetseng tsa motlakase, leha ho le joalo, matla a mochini hangata a hlokahala ka lebelo le fapaneng, moo litsamaiso tsa taolo ea lebelo e seng taba e nyane.Mokhoa o le mong o sebetsang oa ho hlahisa phetoho ea lebelo le se nang mohato ke ho fana ka motlakase oa mekhahlelo e meraro ka maqhubu a feto-fetohang le amplitude bakeng sa enjene ea asynchronous.Lebelo la rotor le itšetlehile ka lebelo la matla a khoheli a potolohang a fanoeng ke stator, kahoo ho fetoha ha maqhubu hoa hlokahala.Ho hlokahala voltage e feto-fetohang, phepelo ea motlakase e fokotsehile ka maqhubu a tlase, 'me hona joale ho tlameha ho fokotsoa ka ho fokotsa motlakase oa phepelo.

Pele ho qaleha ha lisebelisoa tsa elektronike tsa matla, taolo ea ho fokotsa lebelo ea li-motor induction e ile ea finyelloa ka ho fetola li-winds tse tharo tsa stator ho tloha sebakeng sa delta ho ea ho hokahanya ha linaleli, e leng se ileng sa fokotsa motlakase ho pholletsa le maqhubu a motlakase.Li-motors tsa induction li boetse li na le li-winding tse fetang tse tharo tsa stator ho lumella ho fapana ha palo ea lipara tsa lipalo.Leha ho le joalo, enjene e nang le mapheo a mangata e theko e boima haholo hobane enjene e hloka likou tse fetang tse tharo tsa khokahano mme ho na le lebelo le ikhethileng feela le fumanehang.Mokhoa o mong o mong oa taolo ea lebelo o ka finyelloa ka mochini o kenyang leqeba la rotor, moo mapheo a rotor a tlisoang holim'a mehele e thellang.Leha ho le joalo, mokhoa ona o bonahala o tlosa boholo ba melemo ea li-motors tsa induction, ha o ntse o hlahisa tahlehelo e eketsehileng, e ka bakang ts'ebetso e mpe ka ho beha lihanyetsi kapa li-reactances ka letoto ho pholletsa le stator windings ea motor induction.

Ka nako eo, mekhoa e ka holimo e ne e le eona feela e fumanehang ho laola lebelo la li-motor induction, 'me li-motor tsa DC li ne li se li ntse li le teng ka li-drive tse sa tšoaneng tse sa lumelleng ho sebetsa ka li-quadrants tse' nè feela, empa hape li ne li koahela matla a mangata.Li sebetsa hantle haholo ebile li na le taolo e loketseng esita le karabelo e ntle e matla, leha ho le joalo, bofokoli ba eona bo ka sehloohong ke tlhokahalo e tlamang bakeng sa borashe.

Lilemong tse 20 tse fetileng, theknoloji ea semiconductor e hatetse pele haholo, e fana ka maemo a hlokahalang bakeng sa nts'etsopele ea litsamaiso tse loketseng tsa ho khanna likoloi.Maemo ana a oela likarolong tse peli tse kholo:

(1) Phokotso ea litšenyehelo le ntlafatso ea ts'ebetso ea lisebelisoa tsa motlakase tsa motlakase.

(2) Monyetla oa ho kenya tšebetsong li-algorithms tse rarahaneng ho li-microprocessors tse ncha.

Leha ho le joalo, ntho e hlokahalang e tlameha ho etsoa ho hlahisa mekhoa e loketseng ea ho laola lebelo la li-motor induction tseo ho rarahana ha tsona, ho fapana le mokhoa o bonolo oa mochine, ho leng bohlokoa ka ho khetheha mabapi le sebopeho sa tsona sa lipalo (multivariate le nonlinear).
