Product Description

Neodymium Magnets N42 8 in OD x 4 in ID x 1/4 in Wind Turbine

Neodymium Wedge Magnets N42 Wedge Segment 8 in OD x 4 in ID x 1/4 in for Wind Turbine Generators – High-Efficiency Rare Earth Magnets

Engineered for high-efficiency wind turbine generators, these N42 neodymium wedge magnets deliver reliable magnetic performance and durability for renewable energy applications. Designed to form a precise magnetic ring for rotor assemblies, these segments help build powerful, efficient wind turbines with improved output over conventional magnet setups.

Key Features:

• Precision Wedge Segment Design: Each magnet measures 1.57" at the wide end, 0.78" at the narrow end, 2" in length, and 0.25" thick, forming a precise 22.5° segment for circular arrays.
• Modular Magnetic Ring: 16 pieces form a complete 8" OD x 4" ID x 0.25" thick magnetic ring, ideal for wind turbine rotor designs.
• High-Strength N42 Grade: Stronger than N40, N38, and N35 grades, delivering a BrMax of 13,200 gauss for consistent, powerful magnetic performance in energy generation.
• Estimated Pull Force: Rated for optimal holding under ideal conditions, but actual pull may be lower depending on rotor assembly design, alignment, and surface contact.
• Triple Coated: Nickel-Copper-Nickel plating provides superior corrosion resistance and durability, essential for renewable energy systems in diverse environments.
• Magnetized Through Thickness: North and south poles on the flat surfaces for optimal alignment and reliable performance in wind generator assemblies.
• Max Operating Temperature: Rated for continuous use up to 80°C (176°F). Exposure above this temperature may permanently reduce magnetic strength.

Technical Specifications

Frequently Asked Questions

Why choose N42 grade magnets for wind turbines? N42 magnets provide stronger magnetic performance than N35, N38, and N40 grades, helping improve wind turbine efficiency and output.

Are these magnets coated for protection? Yes, they feature a Nickel-Copper-Nickel triple coating for excellent corrosion resistance and durability in various environments.

Will these magnets always provide maximum pull in my wind turbine assembly?
No. Pull force is measured under ideal lab conditions. Actual performance may be lower if surfaces are misaligned, coated, or uneven. Proper alignment and flush contact with ferromagnetic surfaces will maximize performance.

What is the maximum temperature these magnets can safely handle? N42 magnets can be used continuously up to 80°C (176°F). Higher temperatures may permanently reduce magnetic strength.

How are these magnets magnetized? They are magnetized through the thickness, with north and south poles on the flat surfaces for optimal alignment in wind generator assemblies.

Can I use these magnets for DIY wind turbine projects? Yes, these magnets are ideal for engineers, researchers, and DIY builders looking to enhance wind turbine efficiency in renewable energy projects.

Safety Note:

These are extremely powerful and can snap together suddenly, posing a risk of pinching or chipping. Handle with care, keep away from children, sensitive electronics, and pacemakers, and follow all safety guidelines when assembling into rotor systems.
