Tataisong ena ea selelekela, re tla tšohla likarolo tsa 3 phase motor le mesebetsi ea tsona.
Likarolo tsa 3 phase motor:
Li-motor tsa mekhahlelo e meraro li tumme ka lebaka la kaho ea tsona e matla le e tšepahalang.Ha re utloisise likarolo tse 3 tsa motlakase haufi-ufi;
Stator:
Likarolong tsa 3 phase motors, stator ke karolo ea bohlokoa ka ho fetisisa.Ke karolo e emeng e susumetsang rotor hore e tsamaee ka tsela ea matla a khoheli.Karolo ena ea 3 phase motor hape e na le likaroloana tse latelang;
Koko:
Ka hare ho stator, mohaho oa laminated o teng, o tsejoang e le setsi sa stator.Mokotla oa stator o na le li-slots tse kopantsoeng ho latela palo ea lipalo tsa enjene ea motlakase.Li-motor tse ling li na le lipalo tse 2 le li-slots tse 3 kapa lipalo tse 3 le li-slots tse 4, joalo-joalo Lebelo la enjene le fapana ka tsela e fapaneng le palo ea lipalo.Haeba palo ea lipalo e le kholoanyane, lebelo le tla fokotseha 'me ka tsela e fapaneng.
Stator frame:
Sekoahelo se ka ntle sa stator se bitsoa stator frame.Sebopeho sa stator se entsoe ka thepa ea boleng bo phahameng le 100% tšepe e sa hloekang ho sireletsa likarolo tse ka hare.E boetse e netefatsa bophelo bo bolelele le nako e telele.
Stator winding:
Maqhubu a stator a hlahisa matla a khoheli ho stator.Mekhahlelo e meraro ea thaba ha e hokahantsoe le phepelo ea motlakase 'me e qala ho hlahisa matla a khoheli.The stator windings ba insulated le resistive ho etsa bonnete ba tšireletso maemong a sa thabiseng.
Rotor:
Rotor ke karolo e 'ngoe ea bohlokoa likarolong tsa 3 phase motor.Karolo e tsamaeang e potolohang ka lehlakoreng la matla a khoheli e bitsoa rotor.Rotor ea li-motor tsa mekhahlelo e meraro e tsamaisa hona joale ho tsamaisa shaft.Enjene ea mekhahlelo e meraro e boetse e arotsoe ka mekhahlelo e 'meli e meholo ho latela sebopeho sa rotor;
Palesa ea ho thella kapa mofuta oa leqeba:
Rotor ea mofuta oa leqeba ka kakaretso e na le liphaka tse koetsoeng le tse thellang.Li-motor tsena li fana ka torque e phahameng le e sa khaotseng ea ho qala;ka hona, li-motors tsena li sebelisoa haholo indastering ea mojaro o boima hobane e lumella khanyetso ea kantle ho fokotsa nako ea pele.
Setšoantšo sa 2: Rotor ea slip-ring induction motor
squirrel cage motor rotor:
Enjene ea squirrel cage ke eona e sebelisoang haholo ho fetisisa ea mekhahlelo e 3 ka lebaka la kaho ea eona e bonolo ea cage rotor.Rotor ea mofuta oa cage e na le aluminium kapa mekoallo ea koporo e kentsoeng ka har'a li-slots.Mofuta ona oa motlakase oa mekhahlelo e meraro o sebelisetsoa merero e tlaase ea khoebo le ea malapeng.
Lebokose la terminal:
Lebokose la terminal le boetse le hlahelletse likarolong tsa 3 phase motor.Lebokose la terminal le fana ka phepelo ea motlakase ea mekhahlelo e meraro ka phepelo ea motlakase e kantle.Li-winding tsa stator li hokahantsoe le lebokose la terminal ka delta kapa khokahano ea linaleli.
Morati:
Bakeng sa ho qhala mocheso le ho pholisa, fan e nkoa e le karolo ea bohlokoa ea li-motors tsa 3 phase induction.E boloka mocheso le ho pholisa likarolo tse ling tse ka hare tsa 3 phase induction motor.
Motlakase o fana ka li-motor tsa boleng bo holimo tsa OEM, li-motor tsa motlakase tsa karolo e le 'ngoe, le li-motor tsa indasteri lefatšeng ka bophara.
Qetello:
Ho utloisisa likarolo tse 3 tsa makoloi ho u fa mohopolo o pharaletseng oa mochine oa eona oa ho sebetsa, matla a boima le lits'ebetso.Likarolo tsohle tsa li-motors tsa 3 phase induction li kenya letsoho ho fana ka boiphihlelo bo bobebe le ho nepahala.Li-motor tsena li etselitsoe ka ho khetheha ho fana ka torque e phahameng le ts'ebetso ka theko e tlase.U ka ikopanya le rona bakeng sa khotheishene ea mahala le lipotso.Ts'ehetso ea bareki ba rona e sebetsa ntle le tšitiso ho rarolla mathata a hau.
Lipotso tse botsoang khafetsa-3 phase motor parts
1. 3 phase motor ke eng?
Enjene ea induction ea mekhahlelo e meraro ke enjene ea AC e nang le likarolo tse khahlang.Li-motor tsa mekhahlelo e meraro ke li-motor tse iqallang, tse sebetsang hantle le tse tšoarellang nako e telele.Li-motor tsena li sebetsa ho latela molao-motheo oa electromagnetism 'me ha li hloke li-capacitor kapa phepelo ea motlakase ea kantle bakeng sa lipotoloho tsa pele.Li-motor tsena li fana ka matla a 1.5x ho feta li-motor tsa karolo e le 'ngoe.Leha ho le joalo, ho bohlokoa ho utloisisa likarolo tse 3 tsa makoloi, melaoana ea ho sebetsa le ts'ebeliso pele u reka.
2. Likarolo tse 3 tsa motlakase li bitsa bokae?
Likarolo tsa li-motors tsa 3 phase induction li entsoe ka 100% coil ea koporo le tšepe e sa hloekang ho netefatsa bophelo bo bolelele.Li-motor tsena li batla li le theko e boima ho feta li-motor tsa karolo e le 'ngoe ka lebaka la likarolo tsa 3 phase motor le ts'ebetso.Litsenyehelo tsa likarolo tsa motor induction tse tharo li fapana ho ea ka liparamente tse ngata joalo ka mofuta oa voltage, frequency, rpm le mofuta oa kaho.
3. Ke likarolo life tse tsamaeang tse senyehang ka har'a li-motors tsa 3-phase induction?
Likarolo tse tsamaeang tsa 3 phase induction motor tse tsofetseng ke li-bearings le mehele e thellang.Enjene ea 3-phase induction e na le li-bearings tse peli bakeng sa ho potoloha ha shaft.Ka nako e 'ngoe, li-bearings lia fela ka lebaka la tlhokomelo e tlase, liphoso tsa ho jara le ho kenya.Ho feta moo, ho li-motors tsa slip-ring inductions, likarolo tsa 3 phase motor tse tsofetseng ke mehele e thellang.
