A drone brushless motor stator core is the stationary laminated magnetic structure of a brushless motor used in drones and unmanned aerial vehicles. It consists of stacked silicon steel laminations with precision-cut slots for copper windings . When energized by an ESC, the stator generates a rotating magnetic field that drives the rotor—directly determining the motor's torque, efficiency, and thermal behavior.

Reenives manufactures high-quality drone brushless motor 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 35% and ensuring high thermal stability for sustained drone operation .

Reenives offers drone brushless motor stator cores in multiple configurations to meet diverse UAV 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), 0.27mm (aerial photography), and 0.35mm (heavy-lift 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 (salt spray >96h) .
• By Stacking Method: Interlocking self-bonding (≥0.27mm), laser welding, or epoxy bonding (ultra-thin laminations below 0.25mm) .

1. Define power, RPM, and thrust requirements: For FPV racing (>40,000 RPM), select 0.15-0.20mm laminations. For heavy-lift UAVs (15,000-25,000 RPM), 0.20-0.27mm is optimal .
2. Choose lamination material thickness: 0.15mm for premium ultra-high-speed FPV performance; 0.20mm for standard UAV; 0.35mm for robust industrial drone applications .
3. Select slot/pole combination: 9N12P for high RPM racing, 12N14P for balanced torque/speed (most common for UAVs), 18N20P for high torque density heavy-lift .
4. Specify insulation and environmental protection: C5/C6 epoxy coating for outdoor UAVs; anti-corrosion treatment for maritime/agricultural drones .
5. Request samples and validation: Reenives delivers first-article inspection reports (FAI) and material certificates. Prototype drone brushless stator samples ready in 7-10 days after design approval .
