Khatelo-pele, ha u bua ka sena, u ka nahana ka tsoelopele ea ho fumana mangolo a litsebi, joalo ka CET-4 le CET-6.Ka koloing, enjene e boetse e na le mekhahlelo.Letoto mona ha le bue ka bophahamo ba enjene, empa ho lebelo la synchronous la enjene.Ha re nke mohato oa 4 e le mohlala ho bona moelelo o khethehileng oa letoto la likoloi.
Lebelo la 4 la motlakase le bolela lebelo la synchronous la metsotso e 1 ea motlakase = {khafetsa ea phepelo ea motlakase (50Hz) × metsotsoana e 60} ÷ (mehato ea likoloi ÷ 2) = 3000 ÷ 2 = 1500 revolutions.Fekthering, hangata re utloa hore enjene e na le mekhahlelo e mengata.E le hore re utloisise, re tlameha ho qala ho tseba khopolo ea palo: pole e bua ka palo ea khoheli e entsoeng ke rotor ea jenereithara ka mor'a hore motlakase o hlasimollang o sebelisoe ho rotor coil.Ka bokhutšoanyane, ho bolela hore phetoho e 'ngoe le e' ngoe ea rotor e ka etsa hore ho be le mekhoa e mengata ea hona joale ka nako e le 'ngoe ea coil ea stator.Hoa hlokahala ho hlahisa bokhoni ba 50Hz haeba palo ea lipalo e fapane Ho hlokahala lebelo le fapaneng.50Hz, 60 metsotsoana le metsotso (ke hore 3000) arotsoe ka palo ea lipalo ke palo ea revolutions ea enjene ka motsotso.Ho joalo le ka enjene, e leng ts'ebetso e fapaneng ea jenereithara.
Palo ea lipalo e bontša lebelo le lumellanang la enjene.Lebelo la 2-pole synchronous ke 3000rmin, lebelo la 4-pole synchronous ke 1500rmin, lebelo la 6-pole synchronous ke 1000rmin, le lebelo la 8-pole synchronous ke 750rmin.Ho ka utloisisoa hore 2-pole ke palo ea motheo (3000), lipalo tse 4 li ka aroloa feela ka 2, lipalo tse 6 li ka aroloa ka 3, 'me lipalo tse 8 li ka aroloa ka 4. Ho e-na le lipalo tse 2, 3000 e lokela ho ho sebelisoa ho tlosa 2. Ha palo ea lipalo tsa enjene e ntse e eketseha, lebelo la enjene le fokotseha, empa torque ea eona e kholoanyane;ha u khetha enjene, u lokela ho nahana ka torque e qalang e hlokoang ke mojaro.Mohlala, torque e hlokahalang bakeng sa ho qala ka mojaro e kholo ho feta ea ho se qale ho jara.Haeba e le matla a phahameng le mojaro o boima o qala, Ho qala ho theoha (kapa ho qala ha delta ea linaleli) le hona ho tla nahanoa;mabapi le lebelo le tsamaisanang le mojaro ka mor'a ho khetholla palo ea lipalo tsa enjene, e ka nkuoa e le ho khanna ka lebanta la bophara bo fapaneng kapa ka gear e feto-fetohang (Gearbox) Haeba litlhoko tsa matla tsa mojaro li ke ke tsa finyelloa ka mor'a ho etsa qeto. palo ea lipalo tsa enjene ka lebanta kapa phetisetso ea li-gear, matla a tšebeliso ea motlakase a tlameha ho nahanoa.
Enjene ea mekhahlelo e meraro ea AC e entsoe haholo ka stator le rotor.Ha mekhahlelo e meraro ea AC e hokahane le stator, ho tla hlahisoa matla a khoheli a potolohang.Matla a makenete a lula a na le lipalo tse peli (hape ho ka boleloa hore li hlaha ka bobeli), e leng N pole (North Pole) le S pole (south pole) , e tsejoang hape e le palo ea counter.Ha mokhoa o tsoelipanang oa AC motor stator winding o fapane, palo ea lipalo tsa makenete tsa matla a khoheli a potolohang a fapane.Palo ea lipalo tsa makenete e ama lebelo la motlakase ka kotloloho, 'me kamano ea bona ke: lebelo la synchronous = 60 × Frequency level logarithm.Haeba lebelo la synchronous la motor ke 1500 rpm, ho ka baloa hore palo ea logarithm ke 2, ke hore, koloi ea 4-pole ho latela foromo e ka holimo.Lebelo la Synchronous le pole logarithm ke litekanyo tsa mantlha tsa enjene, tse ka fumanoang letlapeng la lebitso la enjene.Hobane pole logarithm e ka ama lebelo la enjene, lebelo la enjene le ka fetoloa ka ho fetola palo ea logarithm ea enjene.
Bakeng sa meroalo ea mokelikeli joalo ka li-fan le lipompo, mofuta ona oa mojaro o na le tšobotsi e hlahelletseng.Joalokaha polelo e bolela, e bitsoa ho hanyetsa phetoho, e bolelang hore mofuta ona oa mojaro o na le khanyetso e kholo ea phetoho ea boemo ba hona joale.Le hoja torque e hlokahalang ho khothalletsa phetoho ea mofuta ona oa mojaro ha e phahame, e hloka matla a mangata ho fetola boemo ba hona joale kapele.E batla e tšoana le metsi a belang.Mollo o monyenyane o ka boela oa pheha, 'me o lokela ho bela haufinyane,' me mollo o ka 'nang oa hlokahala o tla ba moholo haholo.
