Ukuze kuthuthukiswe ikhwalithi yemoto, eminyakeni yamuva nje, umsindo wemoto ufakiwe kwenye yezinkomba zokuhlola ikhwalithi, ikakhulukazi endaweni yokusebenza kwemoto kanye nokuxhumana kwabantu eduze nalesi simo, umsindo wemoto usuphenduke i-motor. izidingo zokuhlola ezibaluleke kakhulu.
Ukuze ulawule i-i-asynchronous motorumsindo, ngaphezu komklamo we-stator kanye ne-rotor slot ngokukhethwa okufanele kwe-stator ne-rotor slot ngaphandle kwe-slot slant ingasetshenziswa ukuze kuncishiswe umsindo we-electromagnetic wenjini. Kodwa ngempela ukuthi ingakanani i-slope slope efaneleke kakhulu, kudingeka ukuhlolwa okwengeziwe ukuze kuqinisekiswe.
Ngokuvamile, i-rotor slot slope yama-asynchronous motors ingathathwa njengendawo eyodwa yezinyo le-stator, engahlangabezana nezidingo. Kodwa-ke, ukuze kuthuthukiswe umsindo we-motor, kuyadingeka ukuhlola umthamo ofanele we-slot, odinga inani elikhulu lokubala nokuqinisekisa.
Ihlaziywa ngombono wokukhiqiza, ukukhiqizwa kwe-slot motor eqondile kanye nokucubungula kube lula, kodwa uma kunesidingo, kuzodingeka kube i-stator slot noma i-rotor slot torsion. I-stator slot torsion inzima, ngakho-ke, ezimweni eziningi, i-rotor slot tilting. I-Rotor slot torsion ngokuvamile ngokusebenzisa i-shaft processing torsion yokhiye wokufinyelela, amabhizinisi wemishini ethuthuke kakhulu, ukusetshenziswa kokushaya okuvunguzayo, kunqubo yokukhiqiza i-rotor core ukuze kuzuzwe.
Izimbangela zomsindo we-electromagnetic kanye nezinyathelo zokugwema
Umsindo wezimoto ubulokhu uyinkinga enzima ukuyixazulula, ukhiqizwa ikakhulukazi yi-electromagnetic, mechanical, ventilation izizathu ezintathu. Umsindo we-electromagnetic ku-asynchronous motor kungenxa ye-stator kanye nama-rotor currents esikhaleni somoya esisungulwe ekusebenzisaneni kwe-harmonic magnetic field kanye ne-electromagnetic force wave ebangelwa ukudlidliza kwejoka okuyisisekelo, okuphoqa okuzungezile.ukudlidliza komoyafuthi kukhiqizwa. Isizathu esiyinhloko kungenxa yokungafaneleki kwesikhala, i-stator ne-rotor eccentricity noma igebe lomoya elincane kakhulu.
Umsindo we-electromagnetic ubangelwa ukungezwani kazibuthe okwenza izinguquko ngesikhathi nendawo futhi kwenziwa izingxenye ezihlukahlukene zenjini. Ngakho-ke, kuma-asynchronous motors, izimbangela zokwakheka komsindo we-electromagnetic zifaka:
● Amagagasi anamandla erediyo endaweni yegebe lomoya inkambu kazibuthe abangela ukuguquguquka kwe-radial nokudlidliza ngezikhathi ezithile kwe-stator ne-rotor.
● Amagagasi anamandla e-Radial ama-harmonics aphezulu endaweni kazibuthe yegebe lomoya asebenza ku-stator kanye nama-rotor cores, awenze aguqeke ngokushintshashintsha kwe-radial nokudlidliza ngezikhathi ezithile.
● Ukuguqulwa kwama-harmonics e-oda ahlukene we-stator core kunamafrikhwensi ahlukene angaphakathi, futhi ukuzwakala kwe-resonance kubangelwa uma imvamisa yegagasi lamandla emitha iseduze noma ilingana neyodwa yamafrikhwensi angaphakathi kwengqikithi.
Ukuguqulwa kwe-stator kubangela ukuba umoya ozungezile udlidlize, futhi iningi lomsindo we-electromagnetic umsindo wokulayisha.
Lapho ingqikithi igcwele, ingxenye yesithathu ye-harmonic iyakhula, futhi umsindo we-electromagnetic uyanda.
Izikhala ze-stator kanye ne-rotor zonke zivulekile, futhi kukhona "amagagasi okuvula i-slot" amaningi akhiqizwa ngaphansi kwesenzo samandla wamagagasi ayisisekelo endaweni kazibuthe yegebe lomoya, futhi igebe lomoya lincane, lapho izikhala ziba banzi, ziba nkulu ama-amplitude azo.
Ukuze ugweme inkinga, ihhovisi elisesiteji sokuklama umkhiqizo ngokusebenzisa izindlela ezithile eziphumelelayo zokuthuthukisa, njengokuthi: ukukhetha ukuminyana okuguquguqukayo kazibuthe okunengqondo, ukukhetha uhlobo olufanele olumazombezombe kanye nenani lemigwaqo ehlobene, ukwandisa inani le-stator. ukubhoboza izikhala, ukunciphisa i-harmonic distribution coefficient of the stator windings, ukucubungula okufanele kwe-stator-rotor air gap motor, ukukhetha i-stator ne-rotor groove nge-rotor slant groove, ukusetshenziswa kwe-rotor, nezinye izinyathelo ezithile.
