Alternator Stator Core

  • High Magnetic Efficiency: Flux density ≥ 1.7 T supports stable current generation and high electrical output.
  • Precision Lamination Alignment: ≤ 0.03 mm deviation maintains flux uniformity and voltage stability.
  • Wide Frequency Adaptability: Effective performance from 50 Hz to 400 Hz for automotive and generator systems.
  • Thermal Endurance: Operates up to 200 °C, suitable for high-speed alternators and demanding environments.
  • Corrosion Protection: Epoxy insulation coating prevents oxidation and extends lifespan.
