Ama-motor kagesi ezigaba ezintathu anokwakhiwa okuqinile okunezingxenye ezihlukene kanye nendlela yokusebenza.Kulezi zinsuku, ama-motors e-3-phase ac induction motors asetshenziswa kakhulu emikhakheni ehlukahlukene yezimboni neyohwebo ngenxa yejubane lawo eliphezulu kanye ne-torque.Ukuqonda izingxenye ezihlukene ze-3 phase motor kubalulekile ekukhetheni okulungele uhlelo lwakho lokusebenza.I-Motor 0 inikezela ngohlu olubanzi lwezinjini zezigaba ezintathu ezihluka kusuka ku-1500rpm-3000rpm.
Umfanekiso 1: 3 isigaba motor izingxenye
Kulo mhlahlandlela oyisingeniso, sizoxoxa ngezingxenye ze-3 ze-motor kanye nemisebenzi yazo.
3 isigaba motor izingxenye:
Ama-motor ezigaba ezintathu adumile ngenxa yokwakhiwa kwawo okuqinile nokuthembekile.Masiqonde izingxenye zezimoto ezi-3 eduze;
Stator:
Ezingxenyeni ezi-3 zama-motor, i-stator iyisakhi esibaluleke kakhulu.Yingxenye emile ethonya i-rotor ukuthi ihambe ibheke endaweni kazibuthe.Le ngxenye ye-3 phase motor inalezi zigatshana ezilandelayo;
Ingqikithi:
Ngaphakathi kwe-stator, isakhiwo se-laminated sikhona, eyaziwa ngokuthi i-stator core.I-stator core inezikhala ezibhanqiwe kuye ngenani lezigxobo zemoto kagesi.Amanye amamotho anezigxobo ezi-2 nezigxobo ezi-3 noma izigxobo ezi-3 nezingu-4, njll. Ijubane lemoto lihambisana ngokuphambene nenani lezigxobo.Uma inani lezigxobo likhulu, isivinini sizoba sincane futhi ngokuphambene nalokho.
Uhlaka lwe-Stator:
Isembozo sangaphandle se-stator sibizwa nge-stator frame.Uhlaka lwe-stator lwakhiwe ngezinto ezisezingeni eliphezulu kanye nensimbi engagqwali engu-100% ukuvikela izingxenye zangaphakathi.Iphinde iqinisekise impilo ende nokuqina.
I-Stator winding:
I-stator winding ikhiqiza izinkambu kazibuthe ku-stator.Izigaba ezintathu ziba nenjabulo lapho zixhunywe kugesi futhi ziqala ukukhiqiza izizinda kazibuthe.I-stator windings i-insulated futhi iphikisana nokuqinisekisa ukuvikelwa ezimweni ezingezinhle.
I-Rotor:
I-Rotor ingenye ingxenye ebalulekile ezingxenyeni ze-3 phase motor.Ingxenye enyakazayo ezungeza iqonde endaweni kazibuthe ibizwa ngokuthi i-rotor.I-rotor yamamotho ezigaba ezintathu ithwala i-current ukuhambisa shaft.I-motor yezigaba ezintathu iphinde ihlukaniswe ngezigaba ezimbili ezinkulu ngokusekelwe ekwakhekeni kwe-rotor;
Indandatho yesiliphu noma uhlobo lwesilonda:
I-rotor yohlobo lwesilonda ngokuvamile iqukethe i-armature eboshiwe namaringi ashelelayo.Lawa ma-motor ahlinzeka nge-torque ephezulu futhi eqhubekayo;ngakho-ke, lawa ma-motor asetshenziswa kakhulu ezimbonini zomthwalo osindayo ngoba kuvumela ukumelana kwangaphandle ukunciphisa okwamanje kokuqala.
Umfanekiso 2: I-Rotor ye-slip-ring induction motor
I-squirrel cage motor rotor:
I-squirrel cage motor iyinjini yokungeniswa kwezigaba ezi-3 esetshenziswa kakhulu ngenxa yokwakhiwa kwayo kwe-cage rotor.I-rotor yohlobo lwekheji iqukethe amabha e-aluminium noma ethusi afakwe ngaphakathi kwezikhala.Lolu hlobo lwenjini enezigaba ezintathu lusetshenziselwa izinjongo zokuhweba ezisezingeni eliphansi nezasekhaya.
Ibhokisi letheminali:
Ibhokisi letheminali libuye livelele ezingxenyeni zezimoto ezi-3.Ibhokisi letheminali lihlinzeka ngogesi wezigaba ezintathu ngokusebenzisa ugesi wangaphandle.Ama-stator windings axhunywe ebhokisini letheminali ngoxhumano lwe-delta noma lwenkanyezi.
Umlandeli:
Ngokuqeda ukushisa nokupholisa, isiphephetha-moya sithathwa njengengxenye ebalulekile yamamotho afakwa esigabeni esi-3.Igcina izinga lokushisa futhi ipholise ezinye izingxenye zangaphakathi ze-3 phase induction motor.
I-Motor iletha ama-OEM motors asezingeni elijwayelekile, amamotho kagesi esigaba esisodwa, namamotho wezimboni emhlabeni jikelele.
Isiphetho:
Ukuqonda izingxenye zezimoto ezi-3 kukunikeza umbono obanzi wendlela yokusebenza kwayo, umthamo wokulayisha, kanye nezinhlelo zokusebenza.Zonke izingxenye ze-3 phase induction motors zifaka isandla ekunikezeni ulwazi olulula nokunemba.Lawa ma-motor aklanyelwe ngokukhethekile ukuhlinzeka nge-torque ephezulu nokusebenza ngentengo efinyelelekayo.Ungasithinta ukuze uthole ikhotheshini kanye nemibuzo.Ukwesekwa kwamakhasimende ethu kusebenza ngaphandle kweziphazamiso ukuze kubhekwane nezinkinga zakho.
Imibuzo evame ukubuzwa-3 isigaba motor izingxenye
1. Iyini i-3 phase motor?
Imotor yezigaba ezintathu induction motor iyinjini ye-AC enezici ezihlaba umxhwele.Amamotho ezigaba ezintathu yizinjini zezimboni eziziqalisayo, ezisebenza kahle futhi ezihlala isikhathi eside.Lawa ma-motor asebenza ngomgomo kazibuthe kagesi futhi awafuni ama-capacitor noma ukunikezwa kwamandla kwangaphandle kokujikeleza kokuqala.Lezi zinjini zinikeza amandla angu-1.5x ngaphezulu kunezinjini zesigaba esisodwa.Kodwa-ke, kubalulekile ukuqonda izingxenye zezimoto ezi-3, izimiso zokusebenza, kanye nokusetshenziswa ngaphambi kokuthenga.
2. Zibiza malini izingxenye ezi-3 zezimoto?
Izingxenye ze-3 phase induction motors zenziwe nge-coil yethusi engu-100% nensimbi engagqwali ukuqinisekisa impilo ende.Lawa ma-motor abiza kakhulu kunamamotho esigaba esisodwa ngenxa yezingxenye ezi-3 zezimoto nokusebenza.Izindleko zezingxenye ezintathu zezingxenye zemoto yokungeniswa ziyahlukahluka ngamapharamitha amaningi njengobubanzi be-voltage, imvamisa, i-rpm, nohlobo lokwakha.
3. Yiziphi izingxenye ezihambayo ezigugayo ezimotweni zokungeniswa kwezigaba ezi-3?
Izingxenye ezihambayo ze-3 phase induction motor ezigugayo zingama-bearings nama-slip rings.I-motor ye-3-phase induction motor inama-bearings amabili wokujikeleza kwe-shaft.Kwesinye isikhathi, ama-bearings ayaphela ngenxa yokulungiswa okuphansi, ukulayisha ngokweqile, namaphutha okufakwa.Ngaphezu kwalokho, kuma-slip-ring induction motors, izingxenye ze-3 phase motor ezigugile ziyizindandatho zokushelela.
