High-performance permanent magnet solutions optimized for industrial systems, automotive drivetrains, and precision sensors.
In modern electromagnetic engineering, the direction of alignment within a permanent magnet determines the efficiency, peak torque output, and operational thermal limits of the overall device. Unlike axial or radial orientation profiles, transverse magnetization forces the magnetic flux paths parallel to the cross-sectional plane, perpendicular to the axis of symmetry.
This specialized alignment technique is key in developing advanced motor architectures, such as Transverse Flux Motors (TFMs) and multi-pole magnetic arrays. Designing these arrays requires a deep understanding of rare-earth metallurgy, precision orienting fields during the powder-compaction phase, and customized sintering treatments to prevent structural micro-cracks.
Your Global Partner for Advanced Rare Earth Permanent Magnets and Custom Assemblies Since 1999
As a national high-tech leader in the rare-earth magnet sector, Zhejiang Laysun Magnetics Ltd. specializes in the design, development, production, and sales of high-performance sintered NdFeB magnets. Over more than 25 years of development, we have established a highly efficient, end-to-end manufacturing process that supplies magnetic solutions to leading global brands in electric vehicles, wind turbines, aerospace, and consumer electronics.
Deploying specialized transverse flux setups to meet the engineering needs of the smart energy era.
Our NdFeB block magnets support high torque-density transverse flux traction motors, reducing rotor weight and increasing range per charge. High thermal grades (AH, EH, SH) guarantee stable performance at temperatures up to 220°C.
Frameless and hollow-shaft motors require highly uniform magnetic fields. Our transverse orientation process provides smooth torque profiles, minimizing cogging torque in multi-axis robotic joints.
Sintered NdFeB arc segments designed for wind power turbines operate under constant load. Superior anti-demagnetization properties ensure operational reliability over long lifespans.
Operating from our modern 100,000 square meter factory in Suining, Sichuan, and headquartered in Hangzhou, China, Zhejiang Laysun Magnetics Ltd. provides end-to-end global supply chain services.
Our facilities house automated production lines, including vacuum induction melting, strip casting, hydrogen decrepitation, jet milling, and transverse field orientation press systems. Coupled with automated sorting and packaging, we guarantee high dimensional accuracy and magnetic properties across large production runs.
To support global partners, we maintain key regional logistics networks, providing fast delivery times and custom warehousing options to meet just-in-time manufacturing schedules.
Pushing the boundaries of magnetic performance while maintaining strict international quality standards.
As the demand for high-temperature stability grows, we continue to develop heavy rare-earth-saving technologies. Using state-of-the-art Grain Boundary Diffusion (GBD), we selectively diffuse Dysprosium (Dy) or Terbium (Tb) through the sintered NdFeB matrix.
This process improves the material's coercivity (Hcj) while preserving remanence (Br) and significantly lowering raw material costs. This allows us to offer competitively priced, high-temperature magnetic systems.
We implement rigorous testing protocols across our entire production line, utilizing specialized equipment such as hysteresisgraphs, salt spray testers, thermal chambers, and PCT/HAST testing equipment.
Our quality management systems meet global standards, ensuring our products comply with environmental regulations such as RoHS, REACH, and WEEE directives, facilitating smooth integration into international projects.
Certified compliance ensures reliability across aerospace, automotive, and industrial applications.

Technical answers regarding magnet design, alignment, and bulk ordering specifications.
Transverse magnetization refers to magnetizing an object perpendicular to its main axis of symmetry or across its width. In contrast, axial magnetization directs the poles through the length of the magnet, and radial magnetization directs the flux from the center outward to the circumference. Transverse magnetization is key for multi-pole rotors, linear actuators, and high-frequency sensor systems where flux must run parallel to the mating surface.
Sintered Neodymium Iron Boron (NdFeB) offers the highest energy product ((BH)max) of any permanent magnet material, often ranging from 35 to 55 MGOe. This high magnetic density allows motors to generate significant torque while remaining compact, making NdFeB magnets standard in EV drivetrains, robotics, and industrial automation.
Uncoated neodymium magnets oxidize easily. We offer various surface coating options, including Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy, Zinc, Gold, and specialized rubber encasing. Our rubber-coated options are ideal for outdoor, marine, or highly humid environments, protecting the sintered core from physical impact and moisture.
We maintain precise dimensional tolerances, typically keeping them within +/-0.05mm, or as tight as +/-0.02mm upon request. Our quality control team uses coordinate measuring machines (CMM), magnetic flux meters, and fluxgate magnetometers to verify magnetic angle consistency, thermal stability, and mechanical strength before shipping.
