Precision Silicon Steel Stator Core with 0.2 mm – 0.5 mm Thickness for OEM/ODM

Our Stator Cores are high-performance electromagnetic components manufactured from precision silicon steel laminations for electric motors, generators, and industrial rotating machinery. Produced using advanced progressive die stamping, high-speed punching, interlocking stacking, and laser welding technologies, our stator cores deliver excellent magnetic performance, low core loss, high efficiency, and stable mechanical structure.

As a professional OEM & ODM manufacturer, we specialize in custom stator cores for EV motors, BLDC motors, servo motors, industrial motors, and generators. We support customers from prototype development to high-volume production with strict quality control and stable manufacturing processes.

A Stator Core is the stationary part of an electric motor or generator that carries alternating magnetic fields to convert electrical energy into mechanical energy (or vice versa). It is made by stacking multiple precision-stamped silicon steel laminations, which reduce eddy current losses and improve overall motor efficiency.

Our stator cores are manufactured from high-grade electrical silicon steel (CRNGO / CRGO) with thicknesses ranging from 0.20 mm to 0.50 mm. Each lamination is precisely stamped using progressive dies to ensure tight tolerances, smooth edges, and consistent magnetic properties.

Depending on application requirements, laminations are assembled using interlocking, riveting, welding, adhesive bonding, or full-stack compression methods. This ensures structural integrity while maintaining optimal electromagnetic performance.
