EV Motor Core

  • Material Flexibility: Nickel alloy, cobalt alloy, and silicon steel for customized performance.
  • Thin Lamination Design: 0.2–0.35 mm sheets minimize eddy-current loss at high speeds.
  • Tight Dimensional Tolerance: ±0.01 mm ensures concentric assembly and quiet operation.
  • High Power Density: ≥ 4.0 kW/kg enables compact, lightweight EV drive systems.
  • Noise Reduction: Optimized skew angle reduces torque ripple and NVH levels.
