Engineered for maximum thrust density, continuous operational reliability, and sub-micron positioning accuracy.
Founded in 1974, our manufacturing enterprise has evolved from foundational electrical winding production into China’s premier engineering hub for high-performance direct drive linear motors and advanced motion control components. Operating out of fully certified, modern manufacturing facilities, we deliver scalable motion solutions tailored for demanding OEM clients worldwide.
Unlike catalogue traders, our engineering capability is deeply rooted on the factory floor. Every linear motor topology—ranging from high-force ironcore actuators to slotless ironless linear motors—is designed, dynamic load tested, and thermally validated under stringent real-world duty cycles before field release.
Understanding the physics of direct drive propulsion for critical automation and semiconductor manufacturing.
Linear motors operate on the basic physical principles of Lorentz force, directly transforming electromagnetic energy into linear mechanical motion without intermediate mechanical transmission systems like ball screws, timing belts, or rack-and-pinion drives. Eliminating these wear-prone components translates to zero backlash, near-infinite mechanical stiffness, extreme acceleration rates, and unprecedented positioning accuracy.
Ironcore linear motors feature electromagnetic coils wound around a laminated steel core. This iron lamination concentrates the magnetic flux generated by high-grade NdFeB magnets, producing exceptionally high continuous and peak thrust forces within a compact volumetric footprint. They represent the optimal choice for high-mass handling, industrial cutting equipment, gantry automation systems, and heavy-duty material processing lines.
Key technical innovations in our ironcore series include anti-cogging skewed tooth profiles and optimized winding fill factors, which reduce force ripple to under 1.5%, enabling smooth constant-velocity scanning even under heavy loads.
Ironless linear motors utilize a self-supporting coil assembly moving within a double-sided U-channel magnet track. Because there is no iron laminations in the moving forcer component, there is zero magnetic attraction force between the forcer and the magnet track, completely eliminating cogging force (torque ripple).
This design yields an extremely light moving mass, enabling ultra-high accelerations (exceeding 10G to 30G) and sub-nanometer velocity stability. Ironless motors are extensively deployed in semiconductor wafer inspection, flat-panel display manufacturing, photonics alignment, and high-speed pick-and-place robotics.

How leading global OEMs are reshaping their supply chains toward direct-drive linear technology.
Global manufacturers in high-precision industries are rapidly phasing out ball-screw and timing-belt mechanical assemblies in favor of direct-drive linear motors. The key drivers are total cost of ownership (TCO), elimination of mechanical backlash, and reduced machine downtime from mechanical wear.
With tightening environmental regulations and surging energy costs across Europe and North America, industrial buyers prioritize high-efficiency linear motors. Advanced copper coil fill techniques and ultra-thin silicon steel laminations significantly reduce hysteresis and eddy current losses during continuous high-frequency cycling.
Modern linear motor procurement goes beyond raw motor hardware. Sourcing managers require direct compatibility with digital industrial networks (EtherCAT, PROFINET, CanOpen). Integrated thermal sensors and digital encoder feedback systems enable real-time predictive maintenance and remote operational diagnostics.
Key innovations driving higher force density, thermal stability, and nanometer precision.
Direct liquid cooling channels embedded within the ironcore forcer coils double continuous thrust capability without increasing physical motor size, maintaining thermal equilibrium under 100% duty cycles.
Co-engineered mounting interfaces for optical and absolute magnetic encoders achieve positioning repeatability down to ±0.1 µm, making these linear motors ideal for semiconductor lithography and optical metrology.
Utilizing Halbach array magnet configurations focuses magnetic flux tightly towards the active coil face while minimizing stray magnetic fields, improving thrust efficiency by up to 25% while protecting sensitive peripheral electronics.
Clear, technical solutions for engineering leads and international procurement managers.
Proper sizing requires defining four critical operational parameters: total payload mass, move distance (stroke), motion profile time (acceleration, constant velocity, deceleration time), and duty cycle. Calculate required Continuous Force ($F_{rms}$) and Peak Force ($F_{peak}$). Our engineering desk provides comprehensive sizing reports matching your dynamic requirements against thermal dissipation limits.
Continuous Thrust ($F_{rms}$) is the maximum force the linear motor can sustain indefinitely without exceeding the maximum allowable winding temperature (typically 120°C to 155°C). Peak Thrust ($F_{peak}$) is the maximum force the motor can produce for short intervals (usually 1 to 3 seconds) during rapid acceleration or deceleration phases.
Yes. Our linear motors are designed with open-architecture 3-phase sinusoidal windings and built-in Hall effect sensors. They are fully compatible with major global industrial servo drives including Siemens, Beckhoff, Omron, Delta, Kollmorgen, and Panasonic operating on EtherCAT, CANopen, or analog interfaces.
We mitigate cogging through proprietary electromagnetic design software, optimizing slot-tooth geometries, implementing skewed stator laminations, and precisely tuning the pitch of high-energy Neodymium magnet tracks. This reduces force ripple to under 1.5%, delivering smooth velocity control.
We offer end-to-end customization including custom coil inductance/voltage matching, specialized mounting plate dimensions, high-flex robot-rated cable lengths, integrated liquid cooling channels, vacuum-rated insulation (up to $10^{-6}$ Torr), and non-magnetic stainless steel encapsulation.
Our manufacturing workflow is certified under ISO9001:2015, CE, and RoHS standards. Every single linear motor undergoes 100% routine electrical testing including insulation resistance (Hi-Pot test), back-EMF constant verification, winding resistance balance check, and dynamic force ripple assessment prior to export packaging.
