Applicable Industry1. Permanent magnet BLDC motors for industrial pumps 2. Servo motors for automation equipment 3. High-efficiency electric generators 4. HVAC fan motors 5. Electric vehicle auxiliary motors 6. Compressor motors for refrigeration

Feature

1. Grade N45SH, maximum continuous operating temperature up to 150°C, strong resistance to demagnetization. 2. Standard segment size OR32.5 × IR29 × H24.9 × 60°, diametrally magnetized, well matched for permanent magnet motor assembly. 3. Strict dimensional tolerance ±0.1mm, consistent arc profile for smooth rotor fitting. 4. Ni-Cu-Ni coating as standard, outstanding anti-corrosion performance for long service life. 5. Stable magnetic flux uniformity, low motor cogging torque for high efficiency operation. 6. Mature mass production process, reliable batch consistency for industrial projects.
