Qhov tsis txaus ntawm cov peev txheej fais fab thoob ntiaj teb lossis kev muab hluav taws xob tab tom loj hlob zuj zus. Ntau lub tuam txhab thiab cov tib neeg xaiv yuavcov khoom siv hluav taws xob dieselrau kev tsim hluav taws xob kom txo qhov kev txwv ntawm kev tsim khoom thiab lub neej los ntawm kev tsis txaus hluav taws xob. Raws li qhov tseem ceeb ntawm lub tshuab hluav taws xob teeb tsa, AC brushless alternators ua lub luag haujlwm tseem ceeb thaum xav txog kev xaiv diesel gensets. Hauv qab no yog cov cim qhia hluav taws xob tseem ceeb ntawm AC brushless alterators:
1. Lub kaw lus txhawb zog. Lub kaw lus txhawb zog ntawm lub tshuab hluav taws xob zoo tshaj plaws ntawm theem tsis ntev los no feem ntau muaj lub tshuab tswj hluav taws xob tsis siv neeg (AVR luv luv), thiab tus tswv tsev stator muab lub zog rau lub stator txhawb zog los ntawm AVR. Lub zog tso zis ntawm lub rotor txhawb zog raug xa mus rau lub rotor ntawm lub cev muaj zog tseem ceeb los ntawm peb-theem puv nthwv dej rectifier. Feem ntau ntawm cov nqi hloov kho hluav taws xob ruaj khov ntawm txhua AVRs yog ≤1%. Cov AVRs zoo heev kuj muaj ntau yam haujlwm xws li kev ua haujlwm sib luag, kev tiv thaiv zaus qis, thiab kev tswj hluav taws xob sab nraud.
2. Kev rwb thaiv tsev thiab kev pleev xim. Qib rwb thaiv tsev ntawm cov alternators zoo feem ntau yog "H". Tag nrho nws cov khoom yog ua los ntawm cov ntaub ntawv tsim tshwj xeeb thiab impregnated nrog cov txheej txheem tshwj xeeb, txhawm rau muab kev lees paub rau kev ua haujlwm hauv ib puag ncig.
3. Kev ua haujlwm ntawm winding thiab hluav taws xob. Lub stator ntawm lub alternator zoo yuav raug laminated nrog cov phaj hlau txias-rolled nrog cov permeability magnetic siab, ob-stacked windings, cov qauv muaj zog thiab kev ua haujlwm rwb thaiv tsev zoo.
4. Kev cuam tshuam los ntawm xov tooj. THF (raws li txhais los ntawm BS EN 600 34-1) yog tsawg dua 2%. TIF (raws li txhais los ntawm NEMA MG1-22) yog tsawg dua 50
5. Kev cuam tshuam xov tooj cua. Cov khoom siv brushless zoo thiab AVR yuav ua kom muaj kev cuam tshuam tsawg kawg nkaus thaum lub sijhawm xa xov tooj cua. Yog tias tsim nyog, tuaj yeem ntsia tau lwm yam khoom siv RFI suppression.
