Kev lag luam hauv kev lag luam
Peb twv tias txoj hauv kev lag luam inverter tseem yuav pom kev loj hlob sai. Raws li kev kwv yees, qhov kev muag khoom ntawm cov lag luam hauv kev lag luam yuav nce tawm ntawm $ 1.2 nphom hauv 2015 mus rau 13.3 nphom hauv xyoo 2030.
Los ntawm qhov muag pom, vim hais tias qhov ratio ntawm inverter rau lub cev muaj zog yog 1: 1, nws yog kwv yees tias tag nrho cov muag yuav nce ntawm 3.6 plhom hauv 2015 mus rau 49 plhom hauv 2030.
Tib lub sijhawm, tus nqi ntawm kev caij luv thij yuav poob ntawm $ 300- $ 400 mus rau $ 200- $ 300, vim yog qhov teebmeem nyiaj tom qab lub ntim.
Zoo ib yam li lub cev muaj zog, Toyota Cov Pab Pawg Sib Koom kuj yog tam sim no ua rau kev lag luam inverter. Tib lub sijhawm, Denso Group, lub koom haum ntawm Toyota Group, yog tam sim no expanding nws cov neeg muas zaub inverter rau ntawm ib tus loj teev. Tom qab Toyota, Mitsubishi Electric kuj muaj kev lag luam ntau heev.
Technological evolution
Los ntawm kev cais ntawm cov motors, nws muaj plaub lub ntsiab lus tseem ceeb: DC, AC induction, synchronization mus tas li thiab hloov maj mam. Lub zog tshiab lub cav tsheb yog siv cov tom kawg ntawm peb.
Tam sim no, synchronization ua lag luam tas li yog lub hauv nruab nrab lub davhlau yam vim nws txoj kev ua tau zoo tshaj plaws. AC asynchronous motors yog pheej yig, tab sis muaj tsawg dua kev kawm thiab siv los ntawm ib co tuam txhab nyob hauv Teb Chaws Asmeskas thiab Tuam Tshoj. Qhov loj ntawm qhov kev hloov maj mam yog qhov lawv tsis tshua muaj nqi, tab sis kuj muaj cov teeb meem ntawm kev ua suab nrov thiab kev sib tw. Yog tias cov teeb meem no muaj peev xwm daws tau, kev hloov tsheb tsis txaus siab yuav muaj kev lag luam loj.
AC asynchronous lub cev: Txawm hais tias los ntawm qhov tam sim no pom, AC asynchronous tsav (nyob fais fab tuag nyob ib ncig ntawm 79-85) tsis muaj zoo dua tshaj li niaj zaus synchronous zog, tab sis nws cov nqi qis dua tshaj ntawm cov hlau nplaum synchronous. Nyob rau hauv cov nqe lus ntawm lub ntim, AC asynchronous motors yog loj tshaj cov hlau nplaum synchronous, tsuas yog vim tsim xyuas.
Cob phum hauv tshuab hluav taws xob (Synchronous engine): Muaj ib lub rotor nrog cov hlau nplaum nyob hauv lub tshuab. Zuag qhia tag nrho lub zog loj (ze ntawm 90-92), thiab qhov ntim yog me me. Tus nqi yog ib qho tseem ceeb, vim yog lub siab tus nqi ntawm cov ntaub ntawv magnet mus tas li. Kev tshawb nrhiav txog kev siv cov hlau nplaum tas li yog tam sim no, thiab kev tshawb fawb kuj yog npaj rau kev txhim kho cov txiaj ntsig ntawm cov hlau nplaum. Cov tshuab hluav taws xob tsis tu ncua yog cov khoom siv dav hlau ntau tshaj plaws rau hauv kev lag luam hluav taws xob hnub no.
Hloov Hloov Pleev Tsav Tsheb: Tus nqi ntawm qhov kev hloov cav tsis tshua muaj kev sib tw, vim yog qhov tsis muaj nqi siab rau hauv nws cov rotor, thiab nws lub zog muaj zog (lub zog nyob ntawm 80-86). Txij thaum rub tawm ntawm lub stator thiab lub rotor yog siv los muab lub hwj chim, qhov kev vibration thiab suab nrov tshwm sim nyob rau hauv txoj kev yog qhov teeb meem loj. Vim hais tias fais fab tsheb cov tsheb tam sim no nyob rau hauv ib lub sijhawm ceev ceev, peb ntseeg hais tias qhov kev nce hauv kev xav yuav ua kom qhov kev hloov tshiab ntawm technology.
