A BLDC stator core is the stationary laminated magnetic structure of a brushless DC motor, consisting of stacked silicon steel laminations with precision-cut slots for copper windings. The stator produces the magnetic force that causes the rotor to spin—it is either inside and surrounded by the rotor (inrunner) or outside enclosing the rotor (outrunner) . The stator core is made up of laminated steel stampings stacked together to form a magnetic core, with coils of wire wound around the core and connected to the controller .

Reenives manufactures high-quality BLDC stator cores using non-grain oriented electrical steel (0.15-0.35mm) with advanced C5/C6 epoxy coating — reducing eddy current losses by up to 38% and ensuring high thermal stability for sustained drone operation .

Reenives offers BLDC stator cores in multiple configurations to meet diverse application requirements :

• By Slot/Pole Config: 9N12P (high RPM racing), 12N14P (balanced torque/speed for UAVs, DLRK), 18N20P (high torque density), 24N28P (heavy-lift / eVTOL) .
• By Material Thickness: 0.15mm (ultra-high performance FPV, 6S), 0.20mm (standard high-frequency UAV/industrial), 0.27mm, and 0.35mm (heavy-duty industrial) .
• By Core Architecture: Segmented stator cores (modular for easy winding, ideal for 5-7 inch FPV racing) and integrated circular laminated stacks (one-piece for heavy-lift agricultural drones) .
• By Insulation Coating: C5 epoxy powder coating (Class H, 180°C) with >2000V dielectric strength; C6 grade for superior thermal conductivity and corrosion resistance .
• By Stacking Method: Interlocking self-bonding (≥0.27mm), laser welding, or epoxy bonding (ultra-thin laminations below 0.25mm) .

1. Define power, RPM, and torque requirements: For FPV racing (>40,000 RPM), select 0.15-0.20mm laminations. For industrial motors (3,000-15,000 RPM), 0.20-0.35mm is optimal .
2. Choose lamination material thickness: 0.15mm for premium ultra-high-speed performance; 0.20mm for standard UAV/industrial; 0.35mm for robust heavy-duty applications .
3. Select slot/pole combination: 9N12P for high RPM racing, 12N14P for balanced torque/speed (most common), 18N20P for high torque density .
4. Specify insulation and environmental protection: C5/C6 epoxy coating for outdoor UAVs; oil-compatible coating for EV/hybrid applications .
5. Request samples and validation: Reenives delivers first-article inspection reports (FAI) and material certificates. Prototype BLDC stator samples ready in 7-10 days after design approval .
