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 se-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, sivame ukusebenzisa ama-ripple resistors enjini. Izinqamuleli ze-Ripple zisebenzisa ama-ripples aqondile ukuze zenze lula ukunqanyulwa kokushisa kanye nokunciphisa i-inductance ye-parasitic, futhi ziphinde zikhethe amalangabi e-inorganic retardant ukuvikela ngempumelelo intambo ephikisayo ekugugeni nokwelula impilo yesevisi.
Ekheshiniama-braking resistors, 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 ngokuzinzile 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.
