Engineers and procurement teams often face two major hurdles when designing next-gen motors:
- Long Material Lead Times: Sourcing 0.10mm JFE Super Core 10JNEX900 typically requires a 3-to-6-month order cycle, delaying prototype testing and time-to-market.
- Complex Processing Requirements: Stamping 0.10mm ultra-thin laminations without burrs is exceptionally challenging, and traditional interlocking or welding destroys insulation layers, ruining high-frequency efficiency.
To bridge this gap from prototype to mass production, Youyou Company maintains a steady inventory of genuine 10JNEX900 raw coils. Paired with our advanced Backlack (self-bonding) technology, we deliver complete "Material + Stamping + Bonding" custom stator core solutions for all HVAC motor applications.
Why 10JNEX900 for HVAC Motors?
Under high VFD carrier frequencies (8kHz–16kHz), standard 0.35mm or 0.20mm electrical steel sheets experience severe eddy current losses, leading to overheating and sharp drops in efficiency.
JFE's 10JNEX900 overcomes this through its 0.10mm ultra-thin gauge and high-silicon chemistry:
- Ultra-Low High-Frequency Core Loss: At 400Hz–2kHz, its core loss is 70%–80% lower than conventional 0.35mm silicon steel, drastically reducing electromagnetic heat generation.
- High Magnetic Flux & Compact Footprint: It retains high permeability while cutting losses, enabling higher power density and compact motor sizing.
- Exceptional NVH (Noise & Vibration) Control: The ultra-thin structure suppresses magnetostriction and slot-cogging torque, eliminating high-frequency hums at the source.
10JNEX900 Stator Core Applications Across HVAC Systems
| HVAC System Area | Motor Application | Youyou Company 10JNEX900 Custom Stator Value |
|---|---|---|
| Compressors | Mag-Lev Centrifugal & Inverter Screw/Heat Pump | Eliminates overheating at 30,000–60,000 RPM, protecting mag-lev bearings and insulation while securing IPLV ratings. |
| Air Handling (AHU/FCU) | EC Axial/Centrifugal Blowers & Supply Fans | Suppresses duct resonance and harmonic noise, meeting stringent noise control standards in hospitals and hotels. |
| Water Loops | Chilled/Condenser Water Pumps & Cooling Tower Fans | Enables pumps to exceed IE5 energy efficiency standards while reducing core temperature to extend motor lifespan. |
| Flow Control | Electronic Expansion Valve (EEV) Steppers | Eliminates response lag in micro-stators, delivering sub-millisecond precision for refrigerant metering. |
| Building Automation | Air/Water Damper Actuators | Lowers switching losses during frequent start-stops and reduces static holding power consumption. |
Backlack (Self-Bonding) Technology: Unlocking 0.10mm Potential
Stamping 0.10mm laminations with traditional interlocking or welding induces mechanical stress and causes edge short-circuits, deteriorating the material's ultra-low loss performance by 30%–50%.
Youyou Company utilizes Backlack self-bonding coating with thermal curing:
- Stress-Free Bonding: Eliminates rivets and welds, preserving 10JNEX900's native electromagnetic properties.
- 98%+ Stacking Factor: Removes interlaminar air gaps, enhancing axial thermal conductivity to dissipate heat rapidly.
- Maximum Structural Rigidity & Noise Reduction: Creates a solid, unified core that absorbs micro-vibrations and eliminates resonance.
