1. Strong & Stable Magnetic Performance: Boasting high remanence, high coercivity and high magnetic energy product, the magnetic field output is strong and evenly distributed, providing sufficient torque for 4KW high-power motors to meet high-load and continuous operation power demands.

2. Excellent Anti-Demagnetization Ability: Magnetic performance attenuation is extremely low. During long-term high-temperature and high-load operation, the magnetic field remains constant without weakening or demagnetization, ensuring sustained and reliable motor power output.

3. Low Loss & High Efficiency: With high resistivity and low eddy current loss, it effectively reduces motor temperature rise, decreases energy consumption, improves motor operation efficiency and extends equipment service life and endurance.

4. Wide Temperature Adaptability: Operates stably in a wide temperature range of -30℃ ~ +70℃, adapting to complex climates such as large temperature difference between day and night, high temperature exposure and low temperature cold in the field.

5. Vibration & Impact Resistance: Dense structure and high mechanical strength enable it to withstand impacts from bumpy movement and frequent vibration of field equipment, without being easily cracked or fallen off.

1. Perfect Matching for 4KW Models: Strictly matches the magnetic circuit design and cavity size of 4KW digital motors with high arc precision, ensuring gap-free assembly without scratching or abnormal noise.

2. Strong Outdoor Adaptability: Dustproof, moistureproof, sandstorm-resistant and corrosion-resistant. No electroplating is required for long-term outdoor use, without rusting, powder shedding or pulverization.

3. Obvious Power Improvement: High magnetic performance significantly boosts motor starting torque and operation stability, making field equipment more powerful, faster-responsive and more reliable in operation.

4. Significant Cost Advantage: 50% lower cost compared with rare earth magnets, while fully meeting the performance requirements of 4KW field motors, leading the industry in cost-performance ratio.

5. Excellent Assembly Performance: Smooth surface and consistent dimensions ensure smooth and efficient assembly, improving the overall assembly yield rate of the motor.
