In peer-reviewed research across publications like the IEEE Robotics and Automation Letters (L-RA), the limits of robot dynamics, joint actuation, and high-performance tactile feedback are constantly being redefined. However, transitioning these high-performance designs from mathematical simulations to physical systems requires materials with supreme physical parameters. Zhejiang Laysun Magnetics Ltd. delivers the high-coercivity, high-remanence permanent NdFeB solutions that enable these next-generation electromagnetic actuators to achieve maximum efficiency and torque-to-weight ratios.
High-performance permanent magnets engineered for extreme industrial duty cycles
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a visionary startup to a nationally recognized high-tech enterprise. Our operations are centered within our state-of-the-art 100,000 square meter manufacturing campus, run by a dedicated team of over 300 experienced research and engineering specialists. With an annual production capacity reaching 5,000 tons of rare earth NdFeB permanent magnets, we serve as a vital backbone for the international robotics, EV, and high-efficiency motor industries.
Translating Robotic Theory into Commercial Dominance
In modern mechanical and robotics engineering literature, particularly inside the issues of the IEEE Robotics and Automation Letters, the spotlight has shifted towards dynamic joint torque densities, localized magnetic transmission gears, and micro-actuators. Robotics design demands lightweight drive configurations that do not compromise on torque output. Rare-earth permanent magnets, specifically Sintered Neodymium-Iron-Boron (NdFeB) blocks and arcs, form the absolute heart of these robotic actuators.
Laysun Magnetics acts as a vital commercial bridge, manufacturing and exporting custom-shaped magnets that implement these complex research papers into real-world applications. Our NdFeB formulations are engineered to provide maximum energy product (BH max) reaching up to 52 MGOe, which allows motor developers to shrink the dimensions of the actuator frame while maintaining massive torque thresholds. This direct alignment with global academic-industrial demands makes our products the premier choice for research labs and high-end manufacturing companies alike.
Cobot joints must remain incredibly responsive and torque-dense. Using our arc segments and permanent rings, engineers design compact outer-rotor frameless motors that sit directly within the robot's articulatory gearboxes.
Surgical arms require sub-millimeter positioning accuracy. Our high-grade Neodymium Voice Coil Motor (VCM) magnets offer linear and hysteresis-free magnetic fields, facilitating ultra-smooth precision movements.
Heavy industrial AGVs require reliable magnetic lifting mechanisms and high-load drive axles. Our NdFeB lifters with up to 1000KG capacity secure massive cargo transitions in automated smart warehouses.
Technological pathways to next-generation electromagnetic designs
To meet the thermal challenges of high-frequency robotic joints, we implement Grain Boundary Diffusion (GBD) technology. GBD allows us to selectively diffuse heavy rare earth elements like Dysprosium (Dy) or Terbium (Tb) through the sintered NdFeB structure. This method significantly increases the magnet's intrinsic coercivity (Hcj) to withstand operating temperatures up to 220°C, without sacrificing the overall remanence (Br) of the material.
Developing multi-layer plating technologies including chemical Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy resin coatings, and Parylene-C deposition to resist extreme moisture and acidic chemical exposures in marine and chemical plants.
Skewing and shaping arc segments to perfectly match complex rotor architectures. This minimizes cogging torque in permanent magnet synchronous motors (PMSM) for humanoid robot movement smooth-control.
Supplying specialized automotive-grade NdFeB rings with strict magnetic angle tolerances for Electric Power Steering (EPS) systems, guaranteeing safety and smooth handling at all times.
System-level integration of permanent magnets across high-demand sectors
Combining 1000KG NdFeB magnetic lifters, permanent block magnets for dynamic magnetic tracks, and brushless motors inside automated forklifts to construct ultra-safe, high-speed logistic terminals.
Customized lightweight ring magnets optimized for high RPM outrunner motors used in commercial payload drones, boosting battery duration by up to 15% through reduced core weight.
High-performance OEM NdFeB arc segments designed specifically for direct-drive wind generator rotors, minimizing maintenance costs and energy conversion losses.
Our engineering philosophy is built on four core pillars: Quality, Credibility, Technology, and Innovation. Zhejiang Laysun Magnetics Ltd. is fully certified to meet the demanding requirements of global supply chains. Our facilities maintain strict compliance with ISO9001 and ISO14001 standards. We also support specialized valve and actuator standards including API 6D, API 607, and CE certifications.
Headquartered in Hangzhou, Zhejiang Province, China, Laysun Magnetics maintains a sprawling factory base in Suining, Sichuan to leverage raw material proximity and processing advantages. This multi-regional coordination allows us to rapidly dispatch large-volume orders to North America, Europe, and major East Asian technology hubs.
Our Quality Assurance team performs strict testing using hysteresisgraph, PCT (Pressure Cooker Test) chambers, and ICP-OES elemental analyzers to confirm material consistency batch after batch.
