Product Description
Unlock High-Performance with N42SH Neodymium Arc Magnets (ID-North)
This premium neodymium arc magnet is crafted from top-quality, high-temperature NdFeB (neodymium-iron-boron) rare earth alloy under strict ISO 9001 quality systems. Engineered to handle demanding industrial environments, the N42SH grade offers exceptional resistance to demagnetization while maintaining robust performance at elevated temperatures.
Rotor Assembly Note: For industrial electric motors, generators, and alternators requiring alternating magnetic poles, this premium inner-diameter North segment is engineered to pair seamlessly with our matching N42SH Arc Magnet ID-South Pole.
Key Specifications & Dimensions:
- Dimensions: Outer Diameter (OD) 1.5" x Inner Diameter (ID) 1.25" x Length (L) 0.75"
- Arc Angle: 45-Degree (8 pieces form a complete 360° circle with OD 1.5" and ID 1.25")
- Pole Orientation: Magnetized through the thickness with the North Pole on the Inner Diameter (ID-N Pole)
- Premium Plating: Triple-layer Ni+Cu+Ni (Nickel-Copper-Nickel) coating for maximum corrosion protection and oxidation resistance
- High-Temperature Rating: Safely operates up to 302°F (150°C) without losing magnetic integrity
Magnetic Characteristics:
- Residual Flux Density (BrMax): 13,200 Gauss
- Coercive Force (Hcb): 13.24 KOe
- Intrinsic Coercive Force (Hcj): 13.42 KOe
- Maximum Energy Product (BH)max: 39.5 MGOe
Industrial Applications:
Engineers and precision manufacturers rely on these curved rare earth segment magnets for high-torque radial magnetic field configurations, including:
- High-efficiency brushless DC motors (BLDC) and servomotors
- Industrial wind turbines and power generators
- Magnetic bearings and magnetic pump couplings
- Advanced automation and robotics assemblies
Safety Note: Neodymium magnets are extremely powerful and brittle. Handle with care to prevent pinching or chipping. Keep away from pacemakers, medical devices, and children.
