2. Kev ua lag luam rub tawm txoj kev loj hlob ntawm sab nraud hlau nplaum brushless lub cev
(1) Cov naj npawb ntawm cov tshuab hluav taws xob siv hauv lub tshav pawb lag luam rau 38% ntawm tag nrho cov tshuab hluav taws xob. HDD ntxaiv motors, tshuab luam ntawv ntxaiv motors, tshuab luam ntawv ntxaiv tshuab, tshuab fais fab, thiab high-end DVD spindle motors yog txhua lub tshuab hluav taws xob uas tsis muaj teeb meem. Ntxiv mus, nws yog ib qho kev txiav txim siab mus tas li magnet brushless tsav. Vim nws cov high precision, nws yog bonded nrog NdFeB. 83% ntawm Nyiv txoj kev koom ua ke NdFeB yog siv rau hom tsob ntoo magnet txhuam tsis tu ncua; tag nrho cov hlua khi yog punched, multipole Concentrated winding, txheej rotor txheej txheem. Kev co motors rau cov xov tooj ntawm tes, lossis cylindrical lossis khawm-hom, feem ntau lawv siv brushed DC motors, tab sis kuj muaj cov tshuab tsis txhuam hauv tshuab, uas tsis siv dav.
(2) Lub cav uas siv hauv tsev tu vaj tse nyob rau li ntawm 15% ntawm tag nrho micro-lub cev. Cov tshuab cua txias, tshuab ntxhua khaub ncaws, cov tub yees thiab lwm yam khoom siv hauv vaj hauv tsev uas siv ib-theem asynchronous motors. Vim tias lawv cov kev ua tau zoo tsawg thiab kev siv tsawg tsawg, kom txuag tau hluav taws xob, muaj peev xwm ua kom muaj zog xws li cov neeg siv khiav ceev asynchronous yog siv thaum xyoo 1990. Tam sim no, ntau tshaj 90% ntawm cov cua txias hauv Nyiv siv cov cua txias. Kev ruaj khov magnet brushless DC lub cev, tsis muaj asynchronous motor zaus conversion hloov, Tuam Tshoj tus cua txias manufacturing cog kuj pib siv magnet brushless DC motor kom tau zoo dua txuag cov nyhuv thiab txuag khoom. Nyob rau ntawm tib lub zog thiab cov nqi ceev, qhov ntim thiab qhov hnyav ntawm ib theem qis dua asynchronous lub cev yog 100%, thiab qhov ruaj khov magnet brushless DC lub cev muaj ib lub ntim ntawm 38%, qhov nyhav ntawm 34.8%, thiab ib txheej tooj ntawm 20.9 %. Tus nqi yog 36.5% thiab kev ua haujlwm nce siab ntxiv los ntawm ntau tshaj 10%. Txhawm rau txhim kho efficiency kom ntau li ntau tau, cov hlau nplaum ntawm lub cav yuav tsum tau sintered NdFeB, lub plhaub taum punching thawm adopts cov hom thaiv los yog pob khawm, ntau tus ncej siab, thiab lub cav yuav ua rau txheej rotor los yog cov qauv rotor puab raws li tus neeg siv yuav tsum tau. Cov cua txias, tshuab ntxhua khaub ncaws, cov tub yees thiab lwm cov khoom siv hauv tsev yuav nce cov qauv siv hluav taws xob tsis tu ncua.
