Indlela Yokuvimbela Ukususwa Kwemagnethi Yama-U Shaped Magnets Ezindaweni Ezishisa Kakhulu

Omaginethi be-neodymium abamise okwe-Uukuletha ukugxila okungenakulinganiswa kwamagnetic - kuze kufike ukushisa. Ezinhlelweni zokusebenza ezifana nezinjini, izinzwa, noma imishini yezimboni esebenza ngaphezu kuka-80°C, ukususwa kwamandla kagesi okungenakuguqulwa kungalimaza ukusebenza. Lapho i-U-magnet ilahlekelwa yi-10% kuphela yokuguquguquka kwayo, insimu egxilile esikhaleni sayo iyawa, okubangela ukwehluleka kohlelo. Nansi indlela yokuvikela imiklamo yakho:

Kungani Ukushisa Kubulala Ama-U Magnet Ngokushesha

Omaginethi be-Neodymium bayayeka ukucindezela amandla okushisa lapho amandla okushisa ephazamisa ukuhambisana kwawo kwama-athomu. Ama-U-shapes abhekene nezingozi ezihlukile:

• Ukucindezeleka kweJomethri: Ukugoba kudala amaphuzu okucindezeleka kwangaphakathi asengozini yokwanda kokushisa.
• Ukuhlushwa Kokujiya: Ubuningi obukhulu bensimu esikhaleni busheshisa ukulahleka kwamandla emazingeni okushisa aphezulu.
• Ukwehluleka Okungalingani: Ukuyeka ugesi ngaphambi komunye kwenza isekethe yamagnetic ingasebenzi kahle.

Isu Lokuvikela Lamaphuzu Amahlanu

1. Ukukhetha Izinto: Qala Ngebanga Elifanele

Akuzona zonke i-NdFeB ezilingana. Beka phambili amazinga aphezulu okuphoqelela (uchungechunge lwe-H):

2. Ukuvikela Ukushisa: Phula Indlela Yokushisa

Ucwaningo lwesigameko: Umenzi we-servo motor unciphise ukwehluleka kwe-U-magnet ngo-92% ngemuva kokufaka ama-mica spacers angu-0.5mm phakathi kwama-coil nama-magnet.

3. Umklamo Wesekethe Kamagnetic: I-Thermodynamics Ehlakaniphile

• Abagcini be-Flux: Amapuleti ensimbi anqamula i-U-gap agcina indlela ye-flux ngesikhathi sokushisa okukhulu.
• Ukwenziwa Kwamaginethi Okungaphelele: Sebenzisa amaginethi ku-70-80% wokugcwala okugcwele ukuze ushiye "igumbi eliyinhloko" lokufudumala kokushisa.
• Imiklamo Evaliwe: Faka omazibuthe be-U ezindlini zensimbi ukuze unciphise ukuvezwa komoya futhi uzinzise ukuhamba komoya.

"I-keeper eklanywe kahle inciphisa ingozi yokususa ugesi ngo-40% ku-150°C uma kuqhathaniswa ne-U-magnets engenalutho."

4. Izivikelo Zokusebenza

• Ama-Curves Ahlukanisayo: Ungalokothi weqe imingcele yokushisa eqondene nebanga elithile (bheka ishadi elingezansi).
• Ukuqapha Ukushisa: Shumeka izinzwa eduze kwe-U-legs ukuze uthole izaziso zesikhathi sangempela.
• Gwema Ukuhamba Ngebhayisekili: Ukushisa/ukupholisa okusheshayo kubangela ukuqhekeka okuncane → ukususwa kwamandla kagesi ngokushesha.

Isibonelo Sejika Elishintshayo (Ibanga le-N40SH):

Ukulahlekelwa yi-Br │ 0% │ 8% │ 15% │ 30%*

5. Ukuhlanganiswa Okuthuthukisiwe Nokubopha

• Ukuqinisa i-Epoxy: Kugcwalisa imifantu emincane evela ekukhuleni kokushisa.
• Izimbozo Ezishisa Kakhulu: I-Parylene HT (≥400°C) idlula i-plating ejwayelekile ye-NiCuNi engaphezu kuka-200°C.
• Ukukhetha Okunamathelayo: Sebenzisa ama-epoxies agcwele ingilazi (izinga lokushisa lesevisi >180°C) ukuvimbela ukwahlukana kwemagnethi.

Amafulegi Abomvu: Ingabe i-U Magnet yakho iyahluleka?

Thola ukukhishwa kwamandla kagesi esigabeni sokuqala:

1. I-Field Asymmetry: umehluko wokuguquguquka >10% phakathi kwemilenze ye-U (linganisa nge-Hall probe).
2. Ukwehla Kwezinga Lokushisa: Imagnethi izwakala ishisa kakhulu kunendawo ezungezile – ikhombisa ukulahleka kogesi we-eddy.
3. Ukwehla Kokusebenza: Ama-motor alahlekelwa yi-torque, ama-sensor abonisa ukuzulazula, ama-separator alahlekelwa yizinto ezingcolisa i-ferrous.

Uma Ukuvimbela Kuhluleka: Amaqhinga Okusindisa

1. Ukuvuselelwa kabusha kogesi: Kungenzeka uma izinto zingalimele ngokwesakhiwo (kudinga insimu yokushaya kwe->3T).
2. Ukuphinda ufake i-coating: Susa i-plating egqwalile, phinda ufake i-coating eshisa kakhulu.
3. Iphrothokholi Yokufaka Esikhundleni: Shintshanisa ngamamaki e-SH/UH + ukuthuthukiswa kokushisa.

Ifomula Ephumelelayo

Ibanga Eliphezulu le-Hci + Ukushisa Okushisayo + Umklamo Wesekethe Ehlakaniphile = Ama-U Magnets Amelana Nokushisa

Ama-magnet e-neodymium anomumo we-U achuma ezindaweni ezinzima uma:

1. Khetha amazinga e-SH/UH ngokwezinga elifanele uma usebenzisa izinhlelo zokusebenza ezingaphezu kuka-120°C
2. Hlukanisa nemithombo yokushisa enezivimbelo zomoya/ze-ceramic
3. Qinisa ukugeleza komoya nabagcini noma izindawo zokuhlala
4. Gada izinga lokushisa esikhaleni
