Self-Bonding Stator Laminations

  • Precision Thickness Control: Stack height tolerance ≤ ±0.02 mm for dimensional stability.
  • High Bonding Strength: Heat-activated resin ensures secure adhesion between laminations under 150–200 °C curing.
  • Improved Magnetic Efficiency: Maintains uniform flux path with no weld-induced stress points.
  • Clean Appearance: No burrs, rivets, or weld marks for improved aesthetics and balance.
  • Lightweight Design: No added fasteners or weld beads, reducing total motor mass.
