Permanent Turbine motor high strong NdFeB Magnets 

1.Product Overview

Tailor-made heat resistant high adhesive force permanent Turbine motor high strong NdFeB Magnets are annular permanent. They are widely used in applications requiring uniform magnetic fields or axial/radial magnetism. With excellent magnetic properties, structural stability, and machining adaptability, they are key components in high-precision elector mechanical systems, inductive devices, and electronic assemblies.

3. Manufacturing Process

The manufacturing procedures of this Tailor-made professional grade high torque heat resistant high adhesive force permanent Turbine motor high strong NdFeB Magnet are as following:

- Pulse Plating: Uses pulsed current control to create denser and more uniform metallic crystal structures. Compared to traditional plating, this significantly improves coating adhesion and corrosion resistance.

- Laser Sealing: High-precision laser scanning seals micro-cracks and pores on the coating surface, improving resistance to moisture, salt spray, and harsh environments. Corrosion resistance can exceed 1000 hours.

- Parylene Vacuum Coating: A conformal polymer layer applied by vapor deposition (CVD). It is pinhole-free, highly insulating, biocompatible, and chemically resistant. Widely used in medical and clean environments. 

Surface Treatment & Plating

To enhance corrosion resistance and appearance:

Default Plating: Triple-layer Ni-Cu-Ni (customizable).

Standard Thickness: Epoxy (12μm)

Optional Plating: Single-layer Zn (5μm) for cost-sensitive projects.

Features:

✔ Salt spray & oxidation resistance

✔ Increased surface hardness (scratch-resistant)

✔ Improved gloss (ideal for exposed components)

Appearance & Dimensional Inspection

Visual Inspection: Under standardized lighting, trained QC staff check for cracks, chipping, inclusions, pores, or oxidation

Image Measurement System: High-res cameras and algorithms conduct non-contact 2D measurements, especially for complex or irregular shapes, ensuring efficiency and objectivity in mass production. 

Automated Intelligent Inspection: High-speed cameras with AI algorithms detect and reject defects (e.g., cracks, scratches, discoloration) and dimensional anomalies, improving yield and reducing human error. 

Magnetic Flux Consistency Test: Fluxmeters or Hall-effect testers measure magnetic flux across batches to ensure uniform performance in end-user applications.

Reliability Testing

Impact & Vibration Test: Simulates shipping and usage conditions to ensure operational stability.

Constant Temperature & Humidity Test: Performed under 85°C and 85% RH for 96–500 hours. Performance and appearance are compared before and after testing.

Applications
Electric Motors & Generators
Application: Precision-engineered magnets are employed in stators, rotors, and brushless DC motors to enhance magnetic flux density, efficiency, and torque performance.

Consumer Electronics
Application: High-performance neodymium magnets are integrated into speakers, haptic systems, vibration motors, and sensors, contributing to compact design and reliable functionality.

Packaging & Transportation

Defect Elimination: 100% inspection using calipers, projectors, visual checks, and automated systems to reject cracked, chipped, oxidized, or coated-defective magnets.

Uniform Magnetization & Structured Arrangement: Magnets are uniformly magnetized and arranged for optimal packaging based on customer requirements to ensure performance and facilitate automated assembly.

Vacuum Sealed Packaging: Multi-layer vacuum sealing with moisture barriers, desiccants or nitrogen, prevents corrosion and magnetic interference during storage and shipping.

Customized Outer Packaging: Shock-proof, moisture-resistant, and anti-magnetic leakage packaging (e.g., multilayer cartons, plastic boxes, metal shielding) ensures compliance with international logistics standards. Each box includes a product list, labels, and tracking codes.

Frequently Asked Questions:

Q: How to choose the correct magnetization direction?

Axial Magnetization: Magnetic lines flow through thickness — best for concentrated fields

Radial Magnetization: Magnetic lines radiate outward — for uniform field distribution

Multipole Magnetization: Multiple poles along circumference — for complex fields (e.g., motors, sensors)

Q: What is the maximum working temperature of a ring magnet?

Standard N-series: up to 80°C

High-temp grades (SH/UH/EH): up to 150°C–230°C

Dysprosium-enriched formulations can further enhance temperature resistance

Q: Does magnetism decay over time?

Under normal conditions (room temp, dry, no heavy vibration), NdFeB magnets exhibit excellent time stability (<5% loss over 10 years). However, factors like:

● Temperature overrun

● Strong external magnetic fields

● Surface corrosion

● Mechanical impact may affect performance.
