Ukudlidliza kweunomphela uzibuthe amamotho synchronousikakhulukazi ivela ezicini ezintathu: umsindo we-aerodynamic, ukudlidliza komshini, nokudlidliza kwe-electromagnetic. Umsindo we-aerodynamic ubangelwa izinguquko ezisheshayo zokucindezela komoya ngaphakathi kwemoto kanye nokungqubuzana phakathi kwegesi nesakhiwo semoto. Ukudlidliza komshini kubangelwa ukuwohloka kwe-elastic ngezikhathi ezithile kwama-bearings, ukukhubazeka kwejometri, nokungalingani kwe-rotor shaft. Ukudlidliza kwe-electromagnetic kubangelwa ukuvuswa kwe-electromagnetic, futhi igebe lomoya kazibuthe lisebenza ku-stator core, okubangela ukuwohloka kwe-radial ye-stator, edluliselwa ku-motor casing bese ikhipha umsindo. Yize ingxenye ye-tangential yenkundla kazibuthe yegebe lomoya incane, ingabangela i-cogging torque ripple kanye nokudlidliza kwemoto. Ekuqhubeni kwe-unomphela uzibuthe amamotho synchronous, i-electromagnetic excitation iwumthombo oyinhloko wokudlidliza.
Esigabeni sokuqala sokuklama kweunomphela uzibuthe amamotho synchronous, ngokusungula imodeli yokusabela yokudlidliza, ukuhlaziya izakhiwo zokuvusa i-electromagnetic kanye nezici eziguquguqukayo zesakhiwo, ukubikezela nokuhlola izinga lomsindo wokudlidliza, nokuthuthukisa umklamo wokudlidliza, umsindo wokudlidliza ungancishiswa, ukusebenza kwemoto kungathuthukiswa, futhi umjikelezo wokuthuthukiswa ungafinyezwa.
Inqubekelaphambili yocwaningo lwamanje ingafingqwa ibe yizici ezintathu:
1.Ucwaningo mayelana nokuvuswa kazibuthe: I-electromagnetic excitation iyimbangela eyinhloko yokudlidliza, futhi ucwaningo seluneminyaka eminingi luqhubeka. Ucwaningo lwangaphambili lwaluhlanganisa ukubala ukusatshalaliswa kwamandla kazibuthe kagesi ngaphakathi kwamamotho kanye nokuthola amafomula okuhlaziya amandla eradial. Eminyakeni yamuva nje, izindlela zokulingisa izinto ezinomkhawulo kanye nokuhlaziywa kwezinombolo ziye zasetshenziswa kabanzi, futhi izazi zasekhaya nezakwamanye amazwe ziye zahlola umthelela wokucushwa kwe-pole slot ku-torque ehlanganisiwe yamamotho kazibuthe ahambisanayo.
2. Ucwaningo mayelana nezici ze-modal yesakhiwo: Izici ze-modal zesakhiwo zihlobene eduze nempendulo yaso yokudlidliza, ikakhulukazi uma i-excitation frequency iseduze nemvamisa yemvelo yesakhiwo, i-resonance izokwenzeka. Izifundiswa zasekhaya nezakwamanye amazwe zifunde izici zesakhiwo zamasistimu e-motor stator ngokuhlolwa nokulingisa, okuhlanganisa izici ezithinta amaza e-modal njengezinto zokwakha, i-elastic modulus, namapharamitha wesakhiwo.
3. Ucwaningo mayelana Nempendulo Yokudlidliza Ngaphansi Kwe-Electromagnetic Excitation: Ukusabela kokudlidliza kwenjini kubangelwe i-electromagnetic excitation esebenza kumazinyo e-stator. Abacwaningi bahlaziye ukusatshalaliswa kwe-spatiotemporal kwamandla kagesi, balayisha injabulo kagesi kusakhiwo se-motor stator, futhi bathola izibalo zezinombolo kanye nemiphumela yokuhlola yempendulo yokudlidliza. Abacwaningi baphinde baphenya umthelela we-coefficient encibilikayo yezinto zegobolondo ekuphenduleni kokudlidliza.
