Raws li peb txhua tus paub, kev txo qis thiab kev kaw ntawm lub cev muaj zog hauv kev tswj hwm zaus tau pom los ntawm kev maj mam txo qhov zaus. Thaum lub sij hawm ntawm kev txo zaus, lub synchronous ceev ntawm lub cev muaj zog kuj txo, tab sis vim mechanical inertia, lub rotor ceev ntawm lub cev muaj zog tseem unchanged. Thaum lub synchronous ceev yog tsawg tshaj li rotor ceev, theem ntawm lub rotor tam sim no hloov los ntawm yuav luag 180 degrees, thiab lub cev muaj zog hloov los ntawm ib tug hluav taws xob lub xeev mus rau lub generating lub xeev. Txhawm rau tiv thaiv lub cev muaj zog thiab haus cov hluav taws xob tsim tawm, peb feem ntau siv ripple resistors hauv lub cev muaj zog. Ripple resistors siv nto ntsug ripples los pab kom cov cua sov dissipation thiab txo cov kab mob parasitic inductance, thiab tseem xaiv cov nplaim retardant inorganic txheej los tiv thaiv cov resistor hlau los ntawm kev laus thiab kev pab lub neej ntev.
Hauv of elevatorbraking resistors, aluminium alloy resistors yog cov tiv taus huab cua thiab kev co ntau dua li cov corrugated resistors, thiab tseem zoo tshaj rau cov tsoos plooj (porcelain skeleton resistors). Nyob rau hauv ib puag ncig kev lag luam hnyav, aluminium alloy resistors feem ntau xaiv. Nws yog ib qho yooj yim rau mount nruj nreem thiab tuaj yeem haum nrog cov dab dej kub. Nyob ntawm qhov xwm txheej, qhov chaw ua haujlwm of elevator kuj tseem tuaj yeem xaiv siv cov khoom siv txhuas. Txawm li cas los xij, feem ntau, feem ntau lub elevator hom muab kev nyiam rau aluminium alloy resistors, uas tuaj yeem ua rau lub elevator muaj kev nyab xeeb dua tom qab kev tu thiab muaj lub neej ua haujlwm ntev.
Raws li cov kev cai sib txawv, aluminium alloy resistors thiab ripple resistors yog siv hauv elevator. Feem ntau, lub braking resistors ntawm elevator yuav tsum ua haujlwm ruaj khov rau lub sijhawm ntev. Yog li ntawd, ntau lub elevator manufacturers yuav xaiv aluminium alloy resistors li braking resistors rau elevator, uas yuav txo tau tus naj npawb ntawm kev kho, xyuas kom meej kev ruaj ntseg ntawm elevator, thiab xyuas kom meej lub lag luam du ntawm motors.
