Vim li cas feem ntau brushless motors tsis siv cov hlau nplaum ferrite?

Jun 22, 2023 Tso lus

Nyob rau hauv ib tug brushless lub cev muaj zog, tsis muaj cov pa roj carbon txhuam, tsis zoo li txhuam, yog li cov hlau nplaum ntawm lub cev tsis muaj zog ua lub rotor.

Brushless lub cev muaj zog, tshwj xeeb tshaj yog cov qauv ntiaj teb brushless lub cev muaj zog, yuav luag 100 feem pua ​​​​ntawm cov hlau nplaum muaj zog nrog Min hlau boron feem ntau yog vim lub xauv hlau boron sib nqus quab yuam muaj zog, lub zog ntawm lub cev muaj zog muaj feem xyuam nrog kev ua haujlwm ntawm cov hlau nplaum, qhov ntim thiab qib ntawm cov hlau nplaum txiav txim siab lub zog siab tshaj plaws ntawm lub cev muaj zog.

Brushless lub cev muaj zog yog ib hom tshiab ntawm lub cev muaj zog, tseem hu ua cov hlau nplaum ruaj khov synchronous lub cev muaj zog. Piv nrog rau cov tsoos brushed DC lub cev muaj zog, brushless lub cev muaj zog txais cov txheej txheem ntawm kev sib nrig sib hloov ntawm DC thiab AC zog, thiab siv cov hlau nplaum tas mus li es tsis txhob txhuam cov tsoos tsho nrog hnav thiab tsim kua muag tshwm sim. Yog li ntawd, brushless motors khiav zoo, tsis tshua muaj suab nrov, kev ua haujlwm siab thiab lub neej ntev, thiab tau siv dav hauv ntau yam cuab yeej hluav taws xob, khoom siv hauv tsev, tsheb hluav taws xob thiab cov qauv dav hlau.

Brushless lub cev muaj zog siv tshuab hluav taws xob tswj kev ceev, uas tuaj yeem hloov kho qhov nrawm raws li kev hloov pauv ntawm kev thauj khoom thiab xyuas kom muaj kev ruaj ntseg ntawm kev ua haujlwm. Nyob rau tib lub sijhawm, brushless motors kuj muaj qhov zoo ntawm qhov pib torque, me me, lub teeb yuag, lub neej ntev thiab kev siv hluav taws xob tsawg, uas yog qhov tsim nyog rau ntau yam kev siv uas yuav tsum muaj kev ua haujlwm siab.

Peb txhua tus paub tias kev ua haujlwm tsis zoo ntawm ferrite, kev ua haujlwm qis ua rau lub cev muaj zog qis, yog li kev siv tsawg heev, uas kuj yog vim li cas ntau tus phooj ywg nug brushless motors tsis siv cov khoom siv hlau nplaum ferrite.
Brushless lub cev muaj zog feem ntau xaiv sintered Chin hlau boron (cov pobzeb) cov khoom, cov khoom sib txuas dun hlau boron (ntiv nplhaib) cov khoom siv, brushless lub cev muaj zog nrog cov pobzeb sib nqus raws li stator, feem ntau ntau tshaj 6 tus ncej, tab sis cov nplais sib nqus raws li lub tshuab tsis txhuam txhuam tig, tuaj yeem muaj ntau dua. tshaj 4, 6 ncej brushless lub cev muaj zog lub nplhaib txoj kab uas hla yog feem ntau ntau dua 20, tus naj npawb ntawm magnetized ncej ntawm 4-12 ncej, thiab nws cov tub ceev xwm thickness ntau tshaj 1.5-5.0 nruab nrab.
