Ukungcangcazelaiimoto ezihambelanayo zemagnethi ezisisigxinaNgokuyintloko ivela kwiinkalo ezintathu: ingxolo ye-aerodynamic, ukungcangcazela koomatshini, kunye nokungcangcazela kwe-electromagnetic. Ingxolo ye-aerodynamic ibangelwa lutshintsho olukhawulezileyo kuxinzelelo lomoya ngaphakathi kwi-motor kunye nokungqubana phakathi kwegesi kunye nesakhiwo se-motor. Ukungcangcazela koomatshini kubangelwa kukuguquka kwe-elastic rhoqo kwee-bearings, iziphene zejometri, kunye nokungalingani kwe-rotor shaft. Ukungcangcazela kwe-electromagnetic kubangelwa kukuvuseleleka kwe-electromagnetic, kwaye i-air gap magnetic field isebenza kwi-stator core, ibangela ukuguqulwa kwe-radial ye-stator, edluliselwa kwi-motor casing kwaye ikhuphe ingxolo. Nangona icandelo le-tangential le-air gap magnetic field lincinci, linokubangela i-cogging torque ripple kunye nokungcangcazela kwe-motor. Kwi-propulsion yeiimoto ezihambelanayo zemagnethi ezisisigxina, ukuvuthuza nge-electromagnetic yeyona nto iphambili ekungcangcazelweni.
Kwinqanaba lokuqala loyiloiimoto ezihambelanayo zemagnethi ezisisigxina, ngokuseka imodeli yempendulo yokungcangcazela, ukuhlalutya iipropati zokuvuselela i-electromagnetic kunye neempawu eziguqukayo zesakhiwo, ukuqikelela nokuvavanya inqanaba lengxolo yokungcangcazela, kunye nokwenza ngcono uyilo lokungcangcazela, ingxolo yokungcangcazela ingancitshiswa, ukusebenza kwemoto kungaphuculwa, kwaye umjikelo wophuhliso ungafinyezwa.
Inkqubela phambili yophando lwangoku ingashwankathelwa kwiinkalo ezintathu:
1. Uphando malunga nokukhuthaza i-electromagnetic: Ukukhuthaza i-electromagnetic yeyona nto iphambili yokungcangcazela, kwaye uphando beluqhubeka iminyaka emininzi. Uphando lwangaphambili luquka ukubala ukusasazwa kwamandla e-electromagnetic ngaphakathi kwee-motors kunye nokufumana iifomyula zohlalutyo zamandla e-radial. Kwiminyaka yakutshanje, iindlela zokulinganisa izinto ezilinganiselweyo kunye nohlalutyo lwamanani ziye zasetyenziswa kakhulu, kwaye iingcali zasekhaya nezangaphandle ziye zafunda impembelelo yeendlela ezahlukeneyo zokumisela i-pole slot kwi-torque ye-cogging yee-motors ezihlala zihleli ze-magnet synchronous.
2. Uphando ngeempawu zemodal zesakhiwo: Iimpawu zemodal zesakhiwo zinxulumene kakhulu nempendulo yaso yokungcangcazela, ingakumbi xa i-frequency yokuvuselela ikufutshane ne-frequency yendalo yesakhiwo, kuya kubakho i-resonance. Iingcali zasekhaya nezangaphandle ziye zafunda iimpawu zesakhiwo seenkqubo ze-motor stator ngokusebenzisa iimvavanyo kunye nokulinganisa, kuquka izinto ezichaphazela i-frequency yemodal ezifana nezixhobo, i-elastic modulus, kunye neeparameter zesakhiwo.
3. Uphando malunga neNkathazo yokuValeka phantsi kweNkathazo ye-Electromagnetic: Impendulo yokuvaleka kwemoto ibangelwa kukuvaleka kwe-electromagnetic okusebenza kumazinyo e-stator. Abaphandi bahlalutye ukusasazwa kwamandla e-electromagnetic ngokwendawo, bafaka i-electromagnetic excitation kwisakhiwo se-motor stator, baza bafumana izibalo zamanani kunye neziphumo zovavanyo zempendulo yokuvaleka. Abaphandi baphande nempembelelo ye-damping coefficient yezinto zegobolondo kwimpendulo yokuvaleka.
