Product Overview
The Small Size Ultra-Thin Segmental Curved NdFeB Magnets are precision-engineered rare-earth magnetic segments tailored for tight spatial constraints and high-performance magnetic circuits. Their curved profile and ultra-thin thickness make them especially suitable for modern compact motors and high-efficiency actuators where every millimeter of radial space matters. These magnets are commonly used in designs where flat block or larger ring magnets cannot be accommodated without compromising performance.
Specifications & Engineering Details
- Material: Sintered Nd–Fe–B (High-energy rare-earth permanent magnet)
- Available Grades: N35–N52 depending on flux and temperature requirements
- Shape: Segmented arc / curved segment - dimensions customisable to match specific rotor/stator curvature
- Thickness: Ultra-thin profile to maximise usable radial space in compact assemblies
- Magnetization: Configurable - typically radial for motors, axial or bespoke as needed
- Surface Coating: Ni-Cu-Ni nickel plating standard; epoxy and zinc coatings available for added corrosion resistance
- Tolerance: Controlled to sub-0.1 mm standards for consistent assembly performance and predictable magnetic behaviour
These magnets can be produced to match specific geometric profiles, enabling seamless integration into tight mechanical tolerances.
Engineering Benefits
- Volume Efficiency: Ultra-thin profile keeps overall motor diameter smaller without sacrificing magnetic output.
- Natural Flux Matching: Curved segment shape matches stator/rotor geometry for smoother flux distribution and reduced cogging.
- High Torque Density: By positioning magnetic material closer to the air gap, torque per unit volume improves versus thicker, conventional magnets.
- Reduced Assembly Complexity: Consistent segmentation and tight tolerances minimise fitting iterations on the production floor.
Typical Applications
- Compact brushless DC motors with limited radial space
- Precision actuators and robotic joints
- Micro-drives in portable devices or wearables
- High-efficiency automotive actuators and sensors
- Custom OEM projects where profile and strength are equally critical
These magnets are suited where design demands a combination of compact form factor and strong magnetic performance.
Procurement & Custom Magnet Support
We offer bulk orders with consistent material properties and quality control protocols. For large-scale production, we provide documentation for magnetic flux (Br), coercivity, dimensional inspection, and coating adhesion. Custom geometries can be produced from supplied drawings or CAD files - simply provide your target dimensions, magnetization requirements, and volume expectations.
Sample quantities are supplied to help you validate performance and fit before committing to full production runs.
FAQ
Q: Can you match custom arc radius or thickness requirements?
A: Yes - we support custom sizes and curvature, tailored to your rotor/stator geometry, with tight tolerance control.
Q: What magnet grades do you recommend for high-temperature environments?
A: For elevated temperature applications, grades above N35 (such as N42, N48) with appropriate coatings are recommended.
Q: Do you supply test reports with shipments?
A: Yes - magnetic flux, dimensional inspection, and coating integrity reports can be provided per batch to support quality assurance.
Q: Is there a minimum order quantity for custom magnets?
A: MOQ depends on complexity; sample quantities for evaluation are available before bulk commitments.
