1. What is a BLDC Stator Lamination? (The Core of Every Brushless Motor)
A BLDC stator lamination is a precision-stamped sheet of electrical steel that forms the stationary core of a brushless DC motor. Multiple laminations are stacked and bonded together to create the stator core, with slots for copper windings. The lamination material, thickness, and insulation coating directly determine eddy current losses, magnetic flux density, and motor efficiency.
Reenives manufactures high-quality BLDC stator laminations using non-grain oriented silicon steel (0.15mm/0.20mm/0.35mm) with advanced C5 epoxy powder coating — ensuring low core loss, high thermal stability, and optimal magnetic performance for drone and industrial applications.
2. BLDC Stator Lamination Classifications
Reenives offers BLDC stator laminations in multiple configurations to meet diverse application requirements:
- By Slot/Pole Config: 9N12P (high RPM racing), 12N14P (balanced torque/speed for UAVs), 18N20P (high torque density), 24N28P (heavy-lift / eVTOL).
- By Material Thickness: 0.15mm (ultra-high RPM >50,000), 0.20mm (standard high-frequency UAV/FPV), 0.27mm, and 0.35mm (general industrial).
- By Insulation Coating: C5 epoxy powder coating (Class H, 180°C) with >1800V dielectric strength.
- By Stacking Method: Interlocking self-bonding, laser welding, or epoxy bonding.
- By Steel Grade: Premium 0.15mm Japanese-grade electrical steel for ultra-high performance; standard 0.20mm grade for most UAV applications.
💡 Reenives specialty: private mould development for custom stator lamination geometries — including skew designs that reduce cogging torque by 30-50% for smoother drone operation.

5. 5-Step Engineering Selection Guide for BLDC Stator Laminations
- Define operating frequency and motor speed: For FPV racing (>40,000 RPM, >40kHz PWM), select 0.15-0.20mm laminations. For standard UAVs (15,000-25,000 RPM), 0.20mm is optimal.
- Choose lamination material thickness: 0.15mm for premium ultra-high-speed performance; 0.20mm for standard high-frequency UAV; 0.35mm for robust industrial motors.
- Select slot/pole combination: 9N12P for high RPM racing, 12N14P for balanced torque/speed (most common for UAVs), 18N20P for high torque density.
- Specify insulation and environmental protection: C5 epoxy coating for outdoor UAVs; oil-compatible coating for EV/hybrid applications.
- Request samples and validation: Reenives delivers first-article inspection reports (FAI) and material certificates. Prototype stator lamination samples ready in 7-10 days after design approval.

6. FAQ – Critical BLDC Stator Lamination Technical Pain Points
Reenives recommends 0.15-0.20mm ultra-thin silicon steel for FPV motors operating above 40,000 RPM. Core loss is ≤8.2-12 W/kg @1.0T/400Hz, ensuring minimal heat generation during aggressive racing.
Our C5 epoxy powder coating provides a uniform 40-80µm layer with >1800V dielectric strength, preventing inter-lamination shorts and moisture ingress. Passes 500h salt spray test (ASTM B117) — critical for agricultural and maritime drone reliability.
Reenives supports standard configurations including 9N12P, 12N14P, 18N20P, and 24N28P — optimized for UAV, FPV, and industrial BLDC applications. Private mould development available for custom geometries.
