Maximize Efficiency with Interlock-Free, Weld-Free Lamination

For motor designers seeking peak performance, minimizing stator iron loss is critical. Our advanced Stator Bonding Technology offers a superior alternative to traditional self-riveting (interlocking) and welding methods. By utilizing high-temperature epoxy bonding, we effectively eliminate interlaminar losses and prevent corrosion, ensuring your motors achieve ultra-low core loss and maximum efficiency.

Key Advantages:

lZero Mechanical Stress: Unlike interlocking or welding, our bonding process introduces no mechanical stress to the laminations, preserving the magnetic properties of the material.

lSuperior Insulation: The high-temperature epoxy provides excellent electrical insulation between layers, significantly reducing eddy current losses.

lEnhanced Corrosion Resistance: The full-surface bonding acts as a protective barrier against moisture and corrosion.

lProven Reliability: This technology has been successfully deployed in mass production for years, delivering consistent quality and an exceptionally low failure rate.

Electrophoretic Coating (Rust - Proof) for Stator Core Lamination

In motor applications exposed to harsh environments, stator core laminations are prone to rust. To address this, the electrophoretic deposition coating process is essential for stator core laminations. Our coating thickness ranges from 0.01mm to 0.025mm.

Leveraging JY's extensive experience in stator rust - proofing, we can support your design to achieve optimal rust - prevention performance, ensuring the durability and reliability of your motor systems.

Standard electrostatic coating machines often struggle to fully coat stator core lamination slots, especially in small corners. Insufficient penetration force can lead to coating thickness not meeting design specs, which harms final motor insulation performance. We’ve optimized our electrostatic coating machine and process to ensure superior coating quality:

1. German - Imported Ejector: Enhances the electrical strength and penetration of the motor insulation powder.

2. Efficiency Boost: Improved by 150% - 200%.

3. Coating Evenness: Reduced from 0.05mm to 0.03mm.

4. Penetration Depth: Increased from 12mm to 17mm.

5. Scrap Rate Reduction for EPS Motor Stator Coil Winding: Solved the pain point, reducing the scrap rate from 30% to 0.1%.

For inner stator laminations with high slot-filling factors, automatic winding machines are often incompatible, requiring manual winding. However, high slot-filling makes copper wires prone to slipping out of slot gaps during high-speed motor operation, risking failure. Our sealed stator coating technology replaces traditional slot wedge assembly, using epoxy powder insulation to fully seal the slot area and eliminate potential motor failures.
