Precision-Grade M350-50A Silicon Steel Laminations‌ – Ultra-Thin (0.5mm) Grain-Oriented Cores for High-Efficiency AC Motors with <0.8W/kg Iron Loss

Product Description:

Our motor laminations are engineered from high-grade, grain-oriented silicon steel that keeps eddy-current losses exceptionally low—under 1.2 W/kg at 1.5 T and 50 Hz—so your machines run cooler and more efficiently. A proprietary, precision-controlled annealing cycle realigns the crystal lattice, boosting peak magnetic flux density to 1.8 T and sharply cutting harmonic distortion, which translates into higher torque with quieter operation. Each lamination is supplied with a uniform, high-dielectric insulation coating applied in-line at the mill; this “stack-ready” finish eliminates the need for post-varnishing and reduces stator or rotor build time by roughly 40 percent. The result is a lightweight, low-loss core that raises motor efficiency, simplifies assembly, and delivers long-term reliability in demanding applications—from high-speed traction drives to compact HVAC compressors.

Features:

⚡ Low Core Loss — Up to 30 % lower than standard laminations
Our grain-oriented silicon-steel stack keeps hysteresis and eddy-current losses to an absolute minimum, delivering a cooler-running, higher-efficiency motor—especially at the elevated switching frequencies typical of modern drive inverters.

⚡ High Saturation Flux — Engineered for demanding EV traction duty
With a saturation flux density approaching 1.8 T, the laminations maintain torque under peak load and high RPM, allowing designers to shrink active‐material mass without compromising power output.

⚡ Custom Geometry — Ready for skewed, helical, or stepped slots
Precision laser blanking and progressive-die stamping support intricate tooth profiles and axial skews that mitigate cogging torque, reduce acoustic noise, and smooth electromagnetic torque ripple.

⚡ Integrated Vibration Damping — Multi-layer adhesive bonding option
An optional viscoelastic inter-layer bonding system sandwiches each lamination in a micro-thin damping film, suppressing structure-borne vibration and cutting overall motor noise by up to 6 dB while improving mechanical robustness during high-speed operation.
