Ukungcangcazela kweumazibuthe osisigxina iimotor synchronousubukhulu becala ivela kwimiba emithathu: ingxolo ye-aerodynamic, ukungcangcazela koomatshini, kunye nokungcangcazela kwe-electromagnetic.Ingxolo ye-Aerodynamic ibangelwa utshintsho olukhawulezayo kuxinzelelo lomoya ngaphakathi kwemoto kunye nokukhuhlana phakathi kwegesi kunye nesakhiwo semoto.Ukungcangcazela komatshini kubangelwa kukuguquguquka kweelastiki ngamaxesha athile, iziphene zejometri, kunye nokungalingani kwe-rotor shaft.Ukungcangcazela kwe-electromagnetic kubangelwa yi-electromagnetic excitation, kwaye umsantsa womoya wemagnethi usebenza kumbindi we-stator, ubangela iradial deformation yestator, ethi idluliselwe kwi-motor casing kwaye ikhuphe ingxolo.Nangona icandelo le-tangential lomsantsa womoya wemagnethi lincinci, linokubangela i-cogging torque ripple kunye nokungcangcazela kwemoto.Kwipropulsion yeumazibuthe osisigxina iimotor synchronous, i-electromagnetic excitation ngowona mthombo wokungcangcazela.
Kwinqanaba lokuqala loyilo lweumazibuthe osisigxina iimotor synchronous, ngokuseka imodeli yokuphendula ye-vibration, ukuhlalutya iimpawu ze-electromagnetic excitation kunye neempawu eziguqukayo zesakhiwo, ukuqikelela nokuvavanya inqanaba lengxolo yokungcangcazela, kunye nokuphucula uyilo lokungcangcazela, ingxolo yokungcangcazela inokuncipha, ukusebenza kwemoto kunokuphuculwa, kwaye umjikelo wophuhliso unokufinyezwa.
Inkqubela yophando yangoku inokushwankathelwa ibe yimiba emithathu:
1.Uphando malunga ne-electromagnetic excitation: I-electromagnetic excitation ngoyena nobangela wokungcangcazela, kwaye uphando beluqhuba iminyaka emininzi.Uphando lwakwangoko lubandakanya ukubala ukuhanjiswa kwamandla ombane we-electromagnetic ngaphakathi kweenjini kunye nokufumana iifomyula zohlalutyo lwamandla emitha.Kwiminyaka yakutshanje, iindlela zokulinganisa izinto ezinomda kunye nohlalutyo lwamanani ziye zasetyenziswa ngokubanzi, kwaye abaphengululi basekhaya nabangaphandle baye bafunda impembelelo yolungelelwaniso lwe-pole slot kwi-torque edibeneyo yeenjini ezisisigxina zemagnethi.
2. Uphando malunga neempawu zemodyuli yesakhiwo: Iimpawu ze-modal zesakhiwo zihambelana ngokusondeleyo nempendulo yayo ye-vibration, ngakumbi xa i-excitation frequency isondele kwi-frequency yendalo yesakhiwo, i-resonance iya kwenzeka.Abaphengululi basekhaya nabangaphandle bafunde iimpawu zesakhiwo senkqubo ye-motor stator ngokusebenzisa imifuniselo kunye nokulinganisa, kubandakanywa izinto ezichaphazela amaza emodyuli anjengemathiriyeli, i-elastic modulus, kunye neeparameters zesakhiwo.
3. UPhando ngeNjongo yeVibration phantsi kwe-Electromagnetic Excitation: Impendulo yokungcangcazela kwemoto yenziwa yi-electromagnetic excitation esebenza kumazinyo estator.Abaphandi bahlalutya ukuhanjiswa kwe-spatiotemporal yamandla ombane we-electromagnetic, balayisha i-electromagnetic excitation kwisakhiwo se-motor stator, kwaye bafumana izibalo zamanani kunye neziphumo zovavanyo lwempendulo yokungcangcazela.Abaphandi baphinde baphanda ifuthe le-coefficient yokumanzisa kwemathiriyeli yeqokobhe kwimpendulo yokungcangcazela.
