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.
