| High Light | high efficiency motor stator core ，silicon steel stator lamination ，EV motor stator core | ||
Our Motor Stator Cores represent the pinnacle of electromagnetic engineering, designed specifically to meet the rigorous demands of next-generation Electric Vehicle (EV) traction motors and high-efficiency industrial drives. We utilize premium, ultra-thin silicon steel laminations to significantly reduce eddy current losses, ensuring maximum energy conversion and thermal stability.
Each stator core is manufactured using state-of-the-art high-speed progressive die stamping technology. This process guarantees exceptional dimensional accuracy and concentricity, which are critical for maintaining a uniform air gap and achieving high torque density. Whether you are developing a high-speed BLDC motor or a heavy-duty EV powertrain, our stator cores provide the structural integrity and magnetic performance required to extend battery life and enhance overall vehicle performance.
Ultra-Low Core Loss: Optimized silicon steel grades (e.g., 0.2mm to 0.35mm thickness) minimize heat generation and energy waste.
High-Precision Stamping: Manufactured with tolerances as tight as ±0.02mm to ensure perfect winding fit and motor balance.
Advanced Bonding Technologies: Options for interlocking, welding, or innovative back-lack (bonding) coating to reduce vibration and noise.
Excellent Thermal Conductivity: Specialized material treatment facilitates rapid heat dissipation during high-speed operation.
High Lamination Factor: Superior stacking techniques ensure more active magnetic material within the same volume for increased power density.

| Dimensional Tolerance | Concentricity & Perpendicularity up to 0.03mm |
| Magnetic Core Loss | Customizable based on grade (e.g., 20PNF1500, 35PN230, etc.) |
| Quality Certification | IATF 16949 (Automotive), ISO 9001:2015, RoHS |
Our stator cores are the "beating heart" of high-performance electrification across various sectors:
Electric Vehicles (EV/HEV): Main traction motors, auxiliary motors for steering, and cooling pump systems.
Industrial Automation: High-torque servo motors for robotics, CNC machinery, and precision manufacturing arms.
Renewable Energy: High-efficiency generators for wind turbines and small-scale hydroelectric systems.
Aerospace & Defense: Lightweight, high-speed motors for drones (UAVs) and aircraft actuators.
HVAC Systems: Energy-saving EC motors for fans, compressors, and industrial ventilation.
We specialize in Tailor-Made Stator Solutions to help you achieve specific performance targets:
Custom Slot Geometry: Optimized slot designs (skewed or straight) to minimize cogging torque and acoustic noise.
Prototype to Mass Production: We offer laser-cut samples for R&D testing before moving to high-volume progressive die production.
Material Selection: Wide range of high-permeability steels from top-tier global mills to suit your frequency requirements.
Complex Assemblies: Capability to provide finished stator stacks with insulation paper, end-caps, or integrated cooling jackets.
Engineering Consultation: Assistance with material selection and DFM (Design for Manufacturing) to reduce production costs.
Magnetic Testing: Comprehensive reporting on iron loss, permeability, and B-H curves for every batch.
Tooling Maintenance: In-house mold workshop ensures zero downtime and consistent part quality throughout the tool's lifespan.
Protective Packaging: Stacks are vacuum-sealed with VCI (Volatile Corrosion Inhibitor) bags and placed in custom-molded foam inserts to prevent tooth deformation during transit.
Heavy-Duty Crating: Shipped in ISPM-15 compliant wooden crates or reinforced plastic pallets for international sea and air freight.
Logistics Tracking: Full door-to-door tracking and digital documentation (MTC, COC) provided for every shipment.
Q: How does lamination thickness affect EV motor performance?
A: Thinner laminations (like 0.20mm) significantly reduce eddy current losses, especially at high frequencies typical of EV motors, leading to higher efficiency and less heat.
Q: Do you support IATF 16949 standards for automotive clients?
A: Yes, our production processes and quality management systems are aligned with IATF 16949 requirements for automotive-grade components.
Q: Can you produce stator cores with skewed slots?
A: Absolutely. We can achieve skewed slot designs through specialized stacking and interlocking techniques to help reduce torque ripple and motor noise.
Q: What is the typical lead time for a new custom stator die?
A: New progressive die development usually takes 4–6 weeks, followed by sample validation and mass production.
