Monga tonse tikudziwa, kuchepetsa liwiro ndi kutseka kwa injini mumayendedwe owongolera pafupipafupi kumazindikirika ndikuchepetsa pang'onopang'ono. Panthawi yochepetsera mafupipafupi, kuthamanga kwa injini kumachepanso, koma chifukwa cha inertia yamakina, liwiro la rotor la injini silinasinthe. Pamene liwiro la synchronous liri locheperapo liwiro la rotor, gawo la rotor panopa limasintha pafupifupi madigiri 180, ndipo galimoto imasintha kuchokera ku magetsi kupita ku dziko lopangira. Kuti titeteze mota ndikuwononga magetsi opangidwa, nthawi zambiri timagwiritsa ntchito ma ripple resistors mu mota. Ma Ripple resistors amagwiritsa ntchito ma ripples apamwamba kuti athetse kutentha ndikuchepetsa kutulutsa kwa parasitic, komanso amasankha zokutira zotchingira moto kuti ziteteze bwino waya wotsutsa kukalamba ndikutalikitsa moyo wautumiki.
Mu elevatorbraking resistors, zodzitetezera za aluminiyamu zimagonjetsedwa ndi nyengo komanso kugwedezeka kusiyana ndi malata, komanso zimakhala zopambana kuposa zotsutsa zachikhalidwe za porcelain skeleton. M'malo ovuta kuwongolera mafakitale, zopinga za aluminium alloy nthawi zambiri zimasankhidwa. Ndiosavuta kukwera mwamphamvu ndipo imathanso kuikidwa masinki otentha. Kutengera momwe zinthu ziliri, malo okwera amathanso kusankha kugwiritsa ntchito zopinga za aluminiyamu. Komabe, kawirikawiri, mitundu yambiri ya elevator imakonda kwambiri zotsutsa za aluminiyamu, zomwe zingapangitse kuti chikepecho chikhale chotetezeka poyang'ana pambuyo pokonza ndikukhala ndi moyo wautali wautumiki.
Pazofunikira zosiyanasiyana, ma aluminium alloy resistors ndi ripple resistors amagwiritsidwa ntchito mu elevator. Nthawi zambiri, ma braking resistors a elevator amafunika kugwira ntchito mokhazikika kwa nthawi yayitali. Chifukwa chake, opanga ma elevator ochulukirapo amasankha ma aluminium alloy resistors ngati ma braking resistors a ma elevator, omwe amatha kuchepetsa kukonzanso, kuonetsetsa chitetezo cha zikepe, ndikuwonetsetsa kuti ma mota akuyenda bwino.
