Stator stampings are precision-punched silicon steel laminations that form the electromagnetic core of a brushless DC motor. The stamping process uses high-speed progressive dies to blank the laminations from electrical steel sheets, determining the dimensional accuracy, burr height, and magnetic properties of every stator core — directly impacting motor efficiency, torque, and thermal performance .

Reenives operates stator stamping lines with imported high-speed presses (up to 600 SPM) and in-die quality monitoring — delivering laminations with burr height ≤0.012mm and consistent stacking factor ≥96.8% .

Reenives offers stator stamping services across multiple configurations to meet diverse application requirements:

• By Lamination Type: Segmented stamping cores (individual teeth assembled), integrated ring stamping cores (one-piece continuous), and custom geometry stamping (skewed slots, trapezoidal teeth) .
• By Slot/Pole Config: 9N12P, 12N14P, 18N20P, 24N28P stator laminations .
• By Material Thickness: 0.20mm (high-frequency UAV/FPV), 0.27mm, and 0.35mm (general industrial) .
• By Stacking Method: Interlocking self-bonding, laser welding, adhesive bonding (epoxy lamination) .
• By Insulation Coating: C3 (organic), C5 epoxy powder coating (Class H, 180°C) with ≥1800V dielectric, and full epoxy powder coating .
