View DetailsIn modern electromagnetics and mechanical engineering, OEM Arc Magnets (commonly referred to as segment magnets) serve as the vital components within brushless motors, permanent magnet synchronous motors (PMSMs), magnetic couplings, and industrial fixing systems. These custom-profiled magnets require extreme precision to ensure uniform flux distribution and optimal torque.
At our advanced production plant, we synthesize Neodymium Iron Boron (NdFeB), Samarium Cobalt (SmCo), and Ferrite segment architectures using state-of-the-art sintering methods. Arc-shaped geometries present unique metallurgical challenges during crystallization and sintering due to the anisotropic orientation requirement of the magnetic domains. Aligning these domains along the radial, diametral, or multi-pole arc trajectories requires custom-designed pressing dies and high-intensity electromagnetic alignment fields.
Selecting the appropriate magnetic compound determines the thermal and mechanical limitations of your motor or assembly. Standard neodymium segments are recognized for their exceptional Maximum Energy Product ((BH)max), reaching values exceeding 52 MGOe. However, for industrial operations exceeding 150°C, Samarium Cobalt (SmCo) becomes the material of choice due to its high Curie temperature and superior temperature coefficient of remanence (αBr).
As global industries prioritize energy conservation, the demand for high-efficiency motors (IE4 and IE5 categories) has accelerated. Our material science division focuses on two major technology initiatives:
This technology allows us to selectively diffuse Dysprosium (Dy) or Terbium (Tb) through the grain boundaries of sintered NdFeB magnets. This technique increases the magnet's intrinsic coercivity (Hcj) without compromising remanence (Br), achieving high thermal stability while reducing rare-earth raw material costs.
By reducing powder particle sizes below 2.5 microns under oxygen-free nitrogen protective environments, we eliminate intergranular defect points. This process results in a highly uniform microcrystalline structure that exhibits superior resistance to corrosion and structural demagnetization.
Moving beyond simple uniaxial dry pressing, we deploy multi-segment split coils inside hydraulic presses. This setup allows for continuous orientation field modification, yielding radial arc segments that provide a sinusoidal magnetic field pattern for smooth, low-cogging motor operation.
These advancements directly benefit our industrial customers by allowing motors to operate at peak torque densities under higher thermal loads. This is particularly advantageous for high-speed EV drivetrains and large-scale industrial servo motors.
While arc segments power rotary motors, flat magnetic assemblies drive modern civil engineering. At QCM Magnet, we bridge the gap between high-performance permanent magnetic material science and heavy-duty precast concrete production equipment.
By using magnetic fixing technologies instead of welding or mechanical bolting on steel casting platforms, manufacturers protect their capital assets from degradation. The integrated magnetic shuttering boxes and chamfers allow for quick design changes, shorten setup cycles, and lower labor overheads. Whether configuring structural wall panels, precast beams, or modular components, our permanent magnetic systems deliver secure holding power and high durability.
