| Keletso ea Bohlokoa: Mekhahlelo ea UH (Ultra High) le EH (Extra High) e tela matla a itseng bakeng sa ho hanyetsa mocheso ka makhetlo a 2-3. |
2. Tšireletso ea Mocheso: Roba Tsela ea Mocheso
| Leqheka | Kamoo e Sebetsang Kateng | Katleho |
|---|---|---|
| Likheo tsa Moea | Arola makenete ho tsoa mohloling oa mocheso | ↓10-15°C libakeng tsa ho kopana |
| Li-insulator tsa Thermal | Li-spacer tsa ceramic/polyimide | Ho tsamaisa li-block |
| Ho Pholisa ho Sebetsang | Lisinki tsa mocheso kapa moea o qobelloang | ↓20-40°C ka har'a likoti |
| Liaparo tse Bonahatsang | Mealo ea khauta/aluminium | E bonahatsa mocheso o phatsimang |
Thuto ea Nyeoe: Moetsi oa enjene ea servo o fokolitse ho hloleha ha makenete ea U ka 92% ka mor'a ho eketsa li-spacer tsa mica tsa 0.5mm pakeng tsa likhoele le makenete.
3. Moralo oa Potoloho ea Magnetic: Thermodynamics e Bohlale ho Feta
- Li-Flux Keepers: Lipoleiti tsa tšepe ho pholletsa le sebaka sa U li boloka tsela ea flux nakong ea ho thothomela ha mocheso.
- Ho Kgothaletsa ka Karolo: Sebelisa makenete ka 70-80% ea ho tlala ho feletseng ho tloha "kamoreng e ka sehloohong" bakeng sa ho phaphamala ha mocheso.
- Meralo ea Loop e Koetsoeng: Kenya li-U-magnets ka har'a matlo a tšepe ho fokotsa ho pepesehela moea le ho tsitsisa phallo.
"Sesebelisoa se entsoeng hantle se fokotsa kotsi ea ho tlosoa ha makenete ka 40% mochesong oa 150°C ha se bapisoa le limakenete tsa U tse se nang letho."
– Litšebelisano tsa IEEE ho Magnetics
4. Litšireletso tsa Ts'ebetso
- Li-Curve tse Fosahetseng: Le ka mohla u se ke ua feta meeli ea mocheso e ikhethileng bakeng sa sehlopha (sheba chate e ka tlase).
- Tlhokomelo ea Thermal: Kenya li-sensor haufi le maoto a U bakeng sa litemoso tsa nako ea sebele.
- Qoba ho Potlaka ka Baesekele: Ho futhumatsa/ho pholisa ka potlako ho baka mapetso a manyane → ho senyeha ha makenete ka potlako.
Mohlala oa Koto e Nyenyane (Kereiti ea N40SH):
Tahlehelo ea Br │ 0% │ 8% │ 15% │ 30%*
5. Liaparo tse Tsoetseng Pele le Tlamahano
- Matlafatso a Epoxy: E tlatsa mapetso a manyane a bakoang ke katoloso ea mocheso.
- Liaparo tsa Mocheso o Phahameng: Parylene HT (≥400°C) e feta plating e tloaelehileng ea NiCuNi e fetang 200°C.
- Khetho ea Sekhomaretsi: Sebelisa li-epoxies tse tletseng khalase (mocheso oa tšebeletso >180°C) ho thibela ho arohana ha makenete.
Lifolakha tse Khubelu: Na Magnet ea Hao ea U ea Hlōleha?
Lemoha demagnetization ea mohato oa pele:
- Ho se leka-lekane ha tšimo: phapang ea phallo ea >10% lipakeng tsa maoto a U (tekanyo ka sesupa-tsela sa Hall).
- Ho Fokotseha ha Thempereichara: Magnet e ikutloa e chesa ho feta tikoloho – e bontša tahlehelo ea motlakase oa eddy.
- Ho Fokotseha ha Tshebetso: Dimotara di lahlehelwa ke torque, disensara di bontsha ho kheloha, di-aparthor di haellwa ke ditshila tsa ferrous.
Ha Thibelo e Hlōleha: Maqheka a ho Pholosa
- Ho tsosolosa makenete: Ho ka etsahala haeba thepa e sa senyeha ka sebopeho (e hloka tšimo ea pulse ea >3T).
- Ho koahela hape: Ho hlobola plating e senyehileng, sebelisa hape plating e nang le mocheso o phahameng.
- Protokhole ea Phetolo: Fetola ka likereiti tsa SH/UH + ntlafatso ea mocheso.
Foromo e Hlōlang
Sehlopha se Phahameng sa Hci + Thermal Buffering + Smart Circuit Design = Limakenete tsa U tse Hanelang Mocheso
