Nzira yeupfu hwesimbi inowanzo shandiswa pakuongorora kwekutanga uye kurongedza nekukurumidza pamutsetse wekugadzira — haina kukodzera QC inobuda, asi yakanaka kwazvo pakuongorora kunouya uye nekukurumidza kusimbisa mushure memagnetization.

Mibvunzo Inowanzo bvunzwa

Mubvunzo: Ko magineti yemhete inogona kugadziriswazve neimwe nzira mushure mekutanga kushandisa magineti here?

A: Kwete. Kune magineti eNdFeB ane sintered ring, magnetic orientation inoonekwa panguva yekudzvanya. Kana yangoiswa magneti, magnetizve neimwe nzira haizoshande nekuti ma domains emagineti anenge atoenderana. Kana uchida kuchinja magneti, unofanira kuodha magineti matsva ane right orientation yakatarwa usati wadzvanya. KuFullzen Technology, tinosimbisa magneti direction mu drawing review stage kudzivirira dambudziko iri.

Q: Magineti ye 30 mm OD ring inogona kutsigira matanda mangani?

A: Magineti ye 30 mm OD ring inogona kutsigira matanda anosvika 16-20, zvichienderana neukobvu hwemadziro uye upamhi hwematanda mashoma. Ne 3 mm ine 3 mm, denderedzwa rekunze rinobvumira matanda angangoita 31, asi zvirambidzo zvinoshanda - kunyatsoita magnetizing fixture, ukobvu hwemadziro, uye kudonha kwemvura pakati pematanda - deredza magadzirirwo mazhinji kusvika 16-20. Tinokurudzira kusimbisa huwandu hwematanda enyu nechikwata chedu cheinjiniya musati maodha matanda.

Q: Sei radial magnetization ichidhura kupfuura axial?

A: Kugadzira magineti eRadial kunoda chigadzirwa chakagadzirwa chinogadzira munda wakasimba weradial kubva kuID kuenda kuOD, izvo zvakaoma kugadzira nekugadzira kupfuura chigadzirwa cheaxial plate chiri nyore. Zvigadzirwa zveRadial zvinowanzodhura ka5-20 kupfuura zvigadziko zveaxial ($600–$6,000+ zvichienderana nehukuru hwering uye nhamba yematanda). Pamusoro pezvo, radial magnetization ine mwero wakaderera wekukohwa (kazhinji 90–95% vs 98%+ yeaxial) nekuda kwezvinodiwa nesimba remunda rakakwirira uye kunyatsorongeka kunodiwa.

Q: Ndeipi nzira yemagnetization yakanakira mota dzeBLDC?

A: Kune akawanda mamota eBLDC, multi-pole radial magnetization ndiyo sarudzo yakajairika. Mamota eInrunner BLDC anowanzo shandisa 8-14 poles; outrunner motors anoshandisa 12-24 poles. Radial field direction (ID-to-OD) inoenderana nenzira yemhepo, zvichipa kushandiswa kwepamusoro kwe15-20% kupfuura axial magnetization. KuFullzen Technology, anopfuura 70% yemirairo yevatengi vedu vemota inotsanangura multi-pole radial magnetization.

Mubvunzo: Ndeipi tembiricha yepamusoro yekushandisa yemagineti ering ane pole dzakawanda?

A: Magineti ering ane pole dzakawanda anotevedzera miganhu yekupisa yakafanana nemagneti ering akajairwa — magiredhi eN35–N45 anoshanda kusvika 80°C, nepo magiredhi eSH achibata 150°C uye magiredhi eUH achibata 180°C. Zvisinei, magineti ane pole dzakawanda anotarisana nenjodzi yakakura yekubvisa magineti pakupisa kwakakwira nekuti zvikamu zvepole zvakatetepa zvine resistance yakaderera yekuzvibvisa magineti. Kune mota dzinoshandiswa pamusoro pe120°C, tinokurudzira kushandisa giredhi re38SH kana 40UH pane N42 yakajairwa.
