Iinkqubo zemagnetization zahluke kakhulu phakathi kweentlobo ezintathu zezinto:

I-Sintered NdFeB (anisotropic): Ifuna amasimi anamandla kakhulu e-pulsed (>3 T) ukuze i-magnetization iphelele. Icala lokuqondisa limiselwa ngexesha lokucinezela; icala lokwazisa kufuneka lihambelane necala lokuqondisa. Ayinakuguqulwa emva kokuba i-magnetization itshintshe.

I-NdFeB edibeneyo (isotropic): Akukho ndlela ikhethwayo yokujongwa; inokwenziwa imagnethi kulo naliphi na icala. Ifuna amandla aphantsi entsimi yemagnethi (>1.5 T); imagnethi enezibonda ezininzi ifikelela lula kwiipateni ezintsonkothileyo. Kodwa imveliso yamandla aphezulu iphantsi ngama-30–40% kune-sintered.

I-NdFeB ebunjiweyo ngenaliti (isotropic): Ukusebenza okuphantsi kwemagnethi (i-BHmax ≈5–10 MGOe), kodwa ingafakwa kwi-injection ibe ziimo ezintsonkothileyo ize ifakelwe imagnethi emva koko. Ifanelekile kwiimo ezingaqhelekanga kunye neeringi ezixineneyo kakhulu ezineepali ezininzi.

Ukuba zeziphi izinto oza kuzikhetha kwiringi yakho yemagnetizing kuxhomekeke ekubeni isicelo sakho sibeka phambili ukusebenza kwemagnetizing vs ubunzima bepateni yemagnetizing. Ukuze usebenze kakuhle, khetha i-sintered; kwiipateni ezintsonkothileyo, khetha i-bonded.

Ukuhlolwa koMgangatho Emva koMagnetization

Yonke iringi enemagnethi kufuneka iphumelele ukuhlolwa ngaphambi kokuba ithunyelwe — nazi iindlela ezintathu ezisemgangathweni esizisebenzisayo kwiFullzen Technology kunye noko nganye nganye ikuqinisekisayo.

Umlinganiselo weHelmholtz Coil (iTotal Flux)

Ikhoyili yeHelmholtz ilinganisa i-total magnetic flux yemagnet — eyona ndlela iphambili yokuqinisekisa i-full magnetization.

Umgaqo:Beka imagnethi ngaphakathi kwikhoyili yeHelmholtz, ulinganise i-voltage ebangelwayo, kwaye ubale i-total flux.

Injongo:Qinisekisa ukuba i-magnetization ifikelele kwi-saturation kwaye amaxabiso e-flux akwi-tolerance (ngesiqhelo ±5%).

Umda:Ingalinganisa kuphela i-total flux; ayinakukwazi ukumisela ukuba usasazo lwentsimi luyafana okanye ukuba kukho ulungelelwaniso phakathi kweepali.

Yonke imagnethi yeFullzen kufuneka iphumelele uvavanyo lwekhoyili yeHelmholtz ngaphambi kokuba ithunyelwe — eli linyathelo lokuqala kwinkqubo yethu eqhelekileyo ye-QC.

Ukuskena iHall Probe (Ukusasazwa kweField)

Ukuskena kweprobe yeHall kulinganisa ukusasazwa kwentsimi yemagnethi kumphezulu wemagnethi — kubaluleke kakhulu kwiiringi ezineepali ezininzi.

Umgaqo:I-Hall probe ijikeleza ize iskena kumphezulu wemagnethi, irekhoda amandla entsimi kwindawo nganye ye-angular.

Injongo:Qinisekisa ulungelelwaniso phakathi kweepali, i-field waveform (ubumsulwa be-sinusoidal/square-wave), kunye nokuhambelana kwe-pole-pitch kwizangqa ze-multi-pole.

I-metric ephambili:Ukuphambuka kwentsimi phakathi kweepali ezikufutshane akufuneki kudlule ±3%; iiringi ze-encoder zifuna ±1%.

Abathengi be-encoder badla ngokufuna iingxelo ze-Hall probe scan. Kwi-Fullzen, le yinto eqhelekileyo ye-QC kwiiringi ze-encoder.

Indlela yoMpuphu weIron (Ukujonga okuKhawulezayo okuBonwayo)

Indlela ye-iron powder yeyona ndlela yokuhlola umgangatho enobuchule kakhulu — i-iron powder efafazwe kumphezulu wemagnethi ihambelana nemigca ye-flux, ityhila ngokuthe ngqo ukusasazwa kwentsimi.

Injongo:Ukuqinisekiswa ngokukhawuleza ukuba icala lemagnetization lichanekile, inani leepali lichanekile, kwaye akukho ziphene ezibonakalayo zemagnetization.

Umda:Umgangatho kuphela; ayiniki manani. Ukuchaneka kungaphantsi kakhulu kunokwe-Hall probe scanning.

Indlela ye-iron powder idla ngokusetyenziselwa ukuhlolwa kwenqaku lokuqala kunye nokuhlela ngokukhawuleza kumgca wemveliso — ayifanelekanga kwi-QC ephumayo, kodwa ilungile kakhulu ekuhlolweni okungenayo kunye nokuqinisekiswa ngokukhawuleza emva kokwenziwa kombane.

FAQ

Q: Ngaba imagnethi yeringi ingaphinda itshatiswe kwicala elahlukileyo emva kokuba itshatiswe okokuqala?

A: Hayi. Kwiimagnethi zendandatho ze-NdFeB ezixutyiweyo, ulwalathiso lwemagnethi lumiselwa ngexesha lokucinezela. Nje ukuba lugxininiswe, ukuphinda lugxininiswe kwicala elahlukileyo akuyi kusebenza kuba iidomeni zemagnethi sele zilungelelanisiwe. Ukuba ufuna ukutshintsha ulwalathiso lwemagnethi, kufuneka u-odole iimagnethi ezintsha ngolwalathiso oluchanekileyo oluchaziweyo ngaphambi kokuba ucinezele. KwiFullzen Technology, siqinisekisa ulwalathiso lwemagnethi kwinqanaba lokuphonononga umzobo ukuze siphephe le ngxaki.

Q: Zingaphi iipali ezinokuxhaswa yimagnethi yeringi ye-OD engama-30 mm?

A: Imagnethi yeringi ye-OD engama-30 mm idla ngokuxhasa ukuya kuthi ga kwiipali ezili-16–20, kuxhomekeke kubukhulu bodonga kunye nobubanzi be-arc ye-pole. Ngomlinganiselo we-arc ye-pole ophantsi we-3 mm, umjikelezo wangaphandle uvumela malunga neepali ezingama-31 ubuninzi, kodwa imida esebenzayo — ukuchaneka kwe-magnetizing fixture, ubukhulu bodonga, kunye nokuvuza kwe-inter-pole flux — kunciphisa uninzi lwee-designs ukuya kwiipali ezili-16–20. Sicebisa ukuqinisekisa inani leepali zakho neqela lethu lobunjineli ngaphambi koku-odola izixhobo.

Q: Kutheni i-radial magnetization ibiza kakhulu kune-axial?

A: Ukufakelwa kwemagnethi yeradial kufuna isixhobo esenziwe ngokwezifiso esivelisa intsimi enamandla yeradial ukusuka kwi-ID ukuya kwi-OD, eyinkimbinkimbi ukuyila nokuyenza kunesixhobo esilula se-axial plate. Izixhobo zeradial zihlala zibiza ngaphezulu ngokuphindwe ka-5-20 kunezixhobo ze-axial ($600–$6,000+ kuxhomekeke kubungakanani beringi kunye nenani leepali). Ukongeza, ukufakelwa kwemagnethi yeradial kunezinga eliphantsi lesivuno (ngesiqhelo yi-90–95% vs 98%+ kwi-axial) ngenxa yeemfuno eziphezulu zamandla entsimi kunye nokuchaneka kokulungelelaniswa okufunekayo.

Q: Yeyiphi ipateni yemagnetization efanelekileyo kwiimoto ze-BLDC?

A: Kwiimoto ezininzi ze-BLDC, i-multi-pole radial magnetization yeyona ndlela iqhelekileyo. Iimoto ze-Inrunner BLDC zihlala zisebenzisa iipali ezi-8-14; iimoto ze-outrunner zisebenzisa iipali ezili-12-24. Icala le-radial field (ID-to-OD) lihambelana nendlela ye-air gap flux, nto leyo ebonelela ngokusetyenziswa okuphezulu nge-15-20% kune-axial magnetization. KwiFullzen Technology, ngaphezulu kwe-70% yee-odolo zabathengi beemoto zethu zichaza i-multi-pole radial magnetization.

Q: Ingakanani iqondo lobushushu lokusebenza eliphezulu kwiimagnethi zeringi ezineepali ezininzi?

A: Iimagnethi zeeringi zeepali ezininzi zilandela imida yobushushu efanayo neemagnethi zeeringi eziqhelekileyo — iigreyidi ze-N35–N45 zisebenza ukuya kuthi ga kwi-80°C, ngelixa iigreyidi ze-SH ziphatha i-150°C kwaye iigreyidi ze-UH ziphatha i-180°C. Nangona kunjalo, iiringi zeepali ezininzi zijongene nomngcipheko ophezulu wokususwa kwemagnethi kumaqondo obushushu aphezulu kuba iindawo zeepali ezincinci zinokumelana okuphantsi kokususwa kwemagnethi. Kwizicelo zeemoto ezingaphezulu kwe-120°C, sicebisa ukusebenzisa i-38SH okanye i-40UH grade endaweni ye-N42 eqhelekileyo.
