I-Sintered NdFeB (anisotropic): Idinga amasimu aqinile kakhulu e-pulsed (>3 T) ukuze kube nogesi ogcwele. Isiqondiso sokuma sisungulwa ngesikhathi sokucindezela; isiqondiso sokumaketha kumele sivumelane nesiqondiso sokumaketha. Ayiguquki ngemva kogesi.

I-NdFeB ehlanganisiwe (isotropic): Ayikho indlela yokuqondisa ekhethwayo; ingafakwa kumagnethi kunoma iyiphi indlela. Idinga amandla aphansi ensimu yokumagnethi (>1.5 T); imagnethi enama-pole amaningi ifinyelela kalula amaphethini ayinkimbinkimbi. Kodwa umkhiqizo wamandla aphezulu uphansi ngo-30–40% kune-sintered.

I-NdFeB ebunjiwe ngomjovo (isotropic): Ukusebenza okuphansi kakhulu kwamandla kazibuthe (i-BHmax ≈5–10 MGOe), kodwa ingabunjwa ngomjovo ibe yizimo eziyinkimbinkimbi bese ifakwa amandla kazibuthe ngemva kwalokho. Ifanele izimo ezingajwayelekile kanye nezindandatho ezincane kakhulu ezinamapali amaningi.

Ukuthi yikuphi okukhethwa kukho kwendandatho yakho yokuzikhandla kuncike ekubekeni phambili ukusebenza kukazibuthe vs ukuba yinkimbinkimbi kwephethini yokuzikhandla. Ukuze uthole ukusebenza okuphezulu, khetha okuhlanganisiwe; ukuze uthole amaphethini ayinkimbinkimbi, khetha okuhlanganisiwe.

Ukuhlolwa Kwekhwalithi Ngemva Kokugqwala

Yonke indandatho enozibuthe kumele iphumelele ukuhlolwa ngaphambi kokuthunyelwa — nansi izindlela ezintathu ezijwayelekile esizisebenzisayo kwa-Fullzen Technology kanye nalokho ngayinye ekuqinisekisayo.

Ukulinganiswa Kwekhoyili yeHelmholtz (I-Total Flux)

Ikhoyili ye-Helmholtz ilinganisa ukugeleza okuphelele kwemagnethi — indlela eyisisekelo kunazo zonke yokuqinisekisa ukugqwala okugcwele.

Isimiso:Faka i-magnet ngaphakathi kwekhoyili ye-Helmholtz, ulinganise i-voltage ebangelwa, bese ubala i-total flux.

Inhloso:Qinisekisa ukuthi i-magnetization isifinyelele ekugcwaleni nokuthi amanani okushintshashintsha angaphakathi kokubekezelelana (ngokuvamile ±5%).

Umkhawulo:Ingalinganisa kuphela ukugeleza okuphelele; ayikwazi ukunquma ukuthi ukusatshalaliswa kwensimu kuyafana noma ukuthi kukhona ukulingana phakathi kwezigxobo.

Wonke umazibuthe we-Fullzen kumele aphumelele ukuhlolwa kwekhoyili ye-Helmholtz ngaphambi kokuthunyelwa — lesi yisinyathelo sokuqala enqubweni yethu ejwayelekile ye-QC.

Ukuskena Kwe-Hall Probe (Ukusabalalisa Insimu)

Ukuskena kwe-Hall probe kulinganisa ukusatshalaliswa kwensimu yamagnetic kuyo yonke indawo yamagnet — okubaluleke kakhulu kumasongo anezinsika eziningi.

Isimiso:I-probe ye-Hall iyajikeleza futhi iskena eduze kobuso bemagnethi, iqopha amandla ensimu endaweni ngayinye ye-angular.

Inhloso:Qinisekisa ukulingana phakathi kwezinsika, isimo segagasi lensimu (ubumsulwa be-sinusoidal/square-wave), kanye nokuvumelana kwe-pole-pitch ezindongeni ze-multi-pole.

Isilinganiso esiyinhloko:Ukuphambuka kwensimu phakathi kwezinsika eziseduze akufanele kudlule ±3%; izindandatho zokufaka ikhodi zidinga ±1%.

Amakhasimende e-encoder ngokuvamile adinga imibiko yokuskena ye-probe ye-Hall. Kwa-Fullzen, lena yinto ejwayelekile ye-QC yama-encoder rings.

Indlela Yokupompa Insimbi (Ukuhlola Okubonakalayo Okusheshayo)

Indlela yempuphu yensimbi iyindlela yokuhlola enembile kakhulu — impuphu yensimbi efafazwe ebusweni bukamagnet ihambisana nemigqa ye-flux, iveza ngqo ukusatshalaliswa kwensimu.

Inhloso:Ukuqinisekiswa okusheshayo kokuthi isiqondiso sokusebenzisa ugesi silungile, inani lezinsika lilungile, futhi azikho iziphambeko ezisobala zokusebenzisa ugesi.

Umkhawulo:Ikhwalithi kuphela; ayinikezi amanani ezinombolo. Ukunemba kungaphansi kakhulu kwalokho kokuskena kwe-probe ye-Hall.

Indlela yempuphu yensimbi ivame ukusetshenziselwa ukuhlolwa kwesihloko sokuqala kanye nokuhlunga okusheshayo emgqeni wokukhiqiza — ayifanele i-QC ephumayo, kodwa ilungele ukuhlolwa okungenayo kanye nokuqinisekiswa okusheshayo ngemuva kokusebenzisa ugesi.

Imibuzo Evame Ukubuzwa

Q: Ingabe i-ring magnet ingaphinde ivuselelwe ngenye indlela ngemva kokuvuselelwa kokuqala?

A: Cha. Kuma-magnets endandatho ye-NdFeB acwebezelayo, ukuqondiswa kwe-magnetic kunqunywa ngesikhathi sokucindezela. Uma sekufakwe i-magnetization, ukuphinde ugxumeke ngendlela ehlukile ngeke kusebenze ngoba izizinda ze-magnetic sezivele ziqondanisiwe. Uma udinga ukushintsha ukuqondiswa kwe-magnetization, kufanele u-ode ama-magnets amasha ngokuqondiswa okufanele okucacisiwe ngaphambi kokucindezela. Kwa-Fullzen Technology, siqinisekisa ukuqondiswa kwe-magnetization esigabeni sokubuyekeza umdwebo ukuze sigweme le nkinga.

Q: Zingaki izinti ezingasekelwa yimagnethi yendandatho engu-30 mm OD?

A: I-magnet yendandatho engu-30 mm OD ngokuvamile ingasekela izingongolo ezifika ku-16-20, kuye ngokuthi udonga lubanzi kangakanani kanye nobubanzi obuncane be-pole arc. Njengoba i-pole arc encane engu-3 mm, umjikelezo wangaphandle uvumela cishe izingongolo ezingu-31 ubuningi, kodwa imikhawulo esebenzayo — ukunemba kwe-magnetizing fixture, udonga lubanzi kangakanani, kanye nokuvuza kwe-inter-pole flux — kukhawulela imiklamo eminingi ibe yizingongolo ezingu-16-20. Sincoma ukuqinisekisa inani lakho lezingongolo nethimba lethu lobunjiniyela ngaphambi koku-oda izingongolo.

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

A: Ukwenziwa kwe-radial magnetization kudinga ukufakwa ngokwezifiso okukhiqiza insimu enamandla ye-radial kusuka ku-ID kuya ku-OD, okuyinkimbinkimbi kakhulu ukuyiklama nokuyikhiqiza kune-axial plate elula. Ukufakwa kwe-radial ngokuvamile kubiza ngaphezulu ngokuphindwe ka-5-20 kune-axial fixtures ($600–$6,000+ kuye ngosayizi wendandatho kanye nenani lezinsika). Ngaphezu kwalokho, ukwenziwa kwe-radial magnetization kunesilinganiso esiphansi sesivuno (ngokuvamile 90–95% vs 98%+ ye-axial) ngenxa yezidingo zamandla ensimu aphezulu kanye nokunemba kokuqondanisa okudingekayo.

Q: Yimuphi umdwebo we-magnetization ongcono kakhulu kuma-motor e-BLDC?

A: Kwabaningi bama-motor e-BLDC, i-multi-pole radial magnetization iyindlela ejwayelekile yokukhetha. Ama-motor e-Inrunner BLDC ngokuvamile asebenzisa izigxobo ezingu-8-14; ama-outrunner motor asebenzisa izigxobo ezingu-12-24. Isiqondiso sensimu ye-radial (ID-to-OD) sihambisana nendlela ye-air gap flux, okunikeza ukusetshenziswa okuphezulu ngo-15-20% kune-axial magnetization. Kwa-Fullzen Technology, ama-oda amakhasimende ethu angaphezu kuka-70% achaza i-multi-pole radial magnetization.

Q: Lingakanani izinga lokushisa lokusebenza eliphezulu lama-magnets endandatho enama-pole amaningi?

A: Omaginethi bezindandatho eziningi balandela imikhawulo yokushisa efanayo namaginethi ezindandatho ajwayelekile — amazinga e-N35–N45 asebenza kuze kufike ku-80°C, kuyilapho amazinga e-SH ephatha u-150°C kanti amazinga e-UH ephatha u-180°C. Kodwa-ke, izindandatho zezingodo eziningi zibhekene nengozi ephezulu yokususa umagnethi emazingeni okushisa aphezulu ngoba izingxenye zezingodo ezincane zinokuphikiswa okuphansi kokususa umagnethi. Ekusetshenzisweni kwezimoto ezingaphezu kuka-120°C, sincoma ukusebenzisa ibanga elingu-38SH noma elingu-40UH kunezinga elijwayelekile le-N42.
