Njengoba sonke sazi, ukuncishiswa kwesivinini kanye nokuvalwa kwemoto ohlelweni lokulawula imvamisa kubonakala ngokunciphisa kancane kancane imvamisa.Ngesikhathi sokunciphisa imvamisa, ijubane le-synchronous le-motor liyancipha, kodwa ngenxa ye-inertia yemishini, isivinini se-rotor motor sihlala singashintshiwe.Uma ijubane lokuvumelanisa lingaphansi kwejubane le-rotor, isigaba se-rotor yamanje sishintsha cishe ngama-degree angu-180, futhi i-motor ishintsha isuka esimweni sikagesi iye esimweni sokukhiqiza.Ukuze sivikele injini futhi sisebenzise ugesi okhiqiziwe, sivamise ukusebenzisa ama-ripple resistors enjini.Izinqamuleli ze-Ripple zisebenzisa ama-ripples aqondile ukuze zenze lula ukunqanyulwa kokushisa futhi zinciphise i-parasitic inductance, futhi ziphinde zikhethe amalangabi e-inorganic retardant ukuvikela ngempumelelo intambo ephikisayo ekugugeni nokwelula impilo yesevisi.
Ekheshiniama-resistors ama-braking, izinto eziphikisayo ze-aluminium alloy zimelana kakhulu nesimo sezulu kanye nokudlidliza kunezinqamuleli zikathayela, futhi futhi ziphakeme kunama-resistors endabuko amathambo e-porcelain.Ezimweni ezinzima zokulawula izimboni, ama-aluminium alloy resistors avame ukukhethwa.Kulula ukukhweza iqine futhi ingafakwa nezisinki zokushisa.Ngokuya ngesimo, izindawo zamakheshi nazo zingakhetha ukusebenzisa izithasiselo ze-aluminium.Kodwa-ke, ngokuvamile, ama-elevator amaningi ama-elevator akhetha kakhulu i-aluminium alloy resistors, engenza i-elevator iphephe ngokuphathelene nokugcinwa kwe-post-maintenance futhi ibe nempilo ende yesevisi.
Ngaphansi kwezidingo ezihlukene, i-aluminium alloy resistors kanye ne-ripple resistors kusetshenziswa kumakheshi.Ezimweni eziningi, ama-resistors okubhuleka wamakheshi adinga ukusebenza ngokuzinza isikhathi eside.Ngakho-ke, abakhiqizi abaningi be-elevator bazokhetha i-aluminium alloy resistors njengama-braking resistors amakheshi, anganciphisa inani lokulungiswa, aqinisekise ukuphepha kwamakheshi, futhi aqinisekise ukusebenza kahle kwezinjini.
