I. I Piniti gi i Industria: I Dilema gi i Manma'gås-ta na Motor
Gi i takhilo' na lina'la' (>10,000 rpm), i manma'usa na asero siha manma'a'ñao nu i lina'la'-ñiha:
- Konbensionåt 3% Silicon Steel (pot hemplo, 0.20 mm): Maolek na magnetisasion (~2.0 T) yan fa'tinas na ma'a'atan. Lao, gi i takhilo' na frekuensiha, i linachi i eddy current dumiminuyi, ya ha na'fanlamen i taotao siha ya ha na'fanlamen i efisiensia.
- Konbensionåt 6.5% Silicon Steel (pot hemplo, JNEX?): Yanggen i 6.5% Si ha na'guaha ultra-low core loss yan near-zero magnetostriction, i saturation magnetization-ña tumunok asta ~1.8 T. Kontodu, i ekstremo na brittleness-ña ha na'fanhuyong i komplikao na tooth slot stamping pat interlocking ni' ti siña ha na'fanhuyong i cheet sin u ma'a'atan yan u ma'a'atan i cheet.
II. Matrix Breakdown: JFE Super Core? Kuåtro na Manå'paka' na Series
Para u ma'ayuda i diferentes na frekuensiha yan nisisidåt aplikasion, ha dibotu i JFE Steel kuatro na diferentes na Super Core? series ni' ma'usa CVD (Chemical Vapor Deposition) na teknolohian silikon. I tiningo' put i posision-ñiha, impottånte para i inayek i materiåt siha:
| Series na Materiåt siha | Prufil i Konsentrasion Si | Saturation Magnetization B<sub>s</sub> (T) | I mas takhilo' na bentaha siha | Primet na Aplikasion siha | Siña Macho'cho' gi i Stamping |
|---|---|---|---|---|---|
| JNEX? | Unifot 6.5% Si gi todu | ~1.80 | Kalang-zero na magnetostriction, ultra-bahu na pineddong | I reaktor siha ni' takhilo' i frekuensian-ñiha, i transfotmadot siha ni' manma'å'agang | Duru (Ma'å'ñao, nisisåriu i carbide die) |
| JNHF? | Si-Gradient (High-Freq Optimized) | ~1.90 | Ti gof takhilo' i pineddong-ña, mas maolek i minetgot-ña | 10kHz+ na reaktor siha, takhilo' na frekuensiha na transfotmadot siha | Mediu |

| JNSF? | Si-Gradient (Low-Freq Optimized) | ~1.95 | Bahu na pineddong gi <400Hz, ti gof åpmam | Servo motor siha gi i industria, ekipåpble ni' takhilo' i efisiensia-ña | Maolek |
III. Microstructural Decoupling: Distribution Gradient & Texture Engineering
JFE JNRF? ha na'guaha dos na inadelanta gi un singkuenta na papet ginen i CVD na sigiente na silikon yan i inadelanta i textura ni' kristalografiku:
� Direksion Si Gradient
Yanggen makontrola i CVD gas-phase na reaksion yan i tiempon difusion, i kapas siha gi hilo' i tano' siña ha håtsa ~6.5% Si ( takhilo' na resistividåt elektrisidåt para u blokeha i eddy currents), mientras i sentråt na hålom guma' ha na'siguru na guaha mas dikike' na konsentrasion Si (ma prebeniyi i ductility, i metgot, yan i takhilo' na magnetization).
� Presisu na Inhenyerian Teksturan Kristalogråfiku
Para u ma na'suha i mas takhilo' na pineddong hysteresis ni' ti ma tungo' gi i 50 Hz asta 1 kHz na rango, JNRF? ha na'halom i teknolohian kontodu i textura:
- I ma'a'atan i ti maolek na granu siha: Ha na'menos i {111} na granu siha ni' manma'a'atan, ni' ti maolek para i soft magnetic na cho'cho'.
- Inadelanta i Manmaolek na Granu siha: Ha na'dokko' i proporsion i {100} yan {110} na granu siha ni' manma'a'atan, ni' manma'a'atan gi i fa'tinas na magnetization axes.
- I Uttimo na Resulta: I magnetization saturation ma'a'ñao asta 2.0 T (parehu yan i 3% Si na asero) mientras ma'a'ñao i ultra-low core loss gi papa' i high-frequency na operasion.
IV. Kumparasion gi i Inayek: JNRF? gi IPM Traction Motors
Sigun ginen i ofisiåt na prublema ginen JFE put un 9 kW, 8-pole 48-slot na Interior Permanent Magnet (IPM) na motor:
| Grådo | Tina'lo' (mm) | Saturation B<sub>s</sub> (T) | I Pineddong W<sub>10/400</sub> (W/kg) | Efisiensia gi 10,000+ rpm | I mas takhilo' na torque T<sub>max</sub> (N�m) | Siña Ma'a'atan yan Ma'a'atan |
|---|---|---|---|---|---|---|
| Konbensionåt 3% Si (20JNEH1500) | 0.20 | 2.0 | ~12.5 | Mas dikike' (Takhilo' na piniti) | 10.8 <em>(Baseline)</em> | Gof maolek |
| High-Si Gradient (10JNHF600) | 0.10 | 1.9 | ~10.1 | Takhilo' (>95%) | 9.9 <em>(8.3% na inañadi)</em> | Siña ha'; nisisåriu i estriktu na die gap control |
