🔧 What is an Electric Stator Core? (BLDC Motor Stationary Assembly)

An electric stator is the fixed electromagnetic component of a brushless DC motor, composed of stacked silicon steel laminations with copper windings. For drone motors, the stator's magnetic properties directly influence torque density, efficiency, and thermal performance. Reenives manufactures custom electric stator cores using high-grade non-grain-oriented electrical steel (0.15mm–0.35mm thickness) with precision stamping and green epoxy insulation coating that withstands up to 200°C. Our proprietary stacking process achieves >97% stacking factor, reducing eddy current loss by up to 24% compared to conventional laminations.

📂 Electric Stator Classification – Match Your Motor Architecture

Reenives categorizes electric stator laminations based on critical engineering parameters. Select the optimal class for your drone, UAV, or industrial BLDC application:

• By Silicon Steel Grade: 0.15mm (ultra-high frequency, FPV racing >50k RPM), 0.20mm (performance cinewhoop), 0.27mm (heavy-lift industrial drones), 0.35mm (cost-effective general purpose).
• By Stacking Method: Interlocking self-bonding, laser welding, or epoxy-impregnated for vibration damping and noise reduction.
• By Insulation Coating: C3 (standard), C5 (enhanced thermal), or C6 epoxy powder coating — C6 grade provides superior dielectric strength (>1200V) and salt spray resistance (>96h).
• By Slot/Pole Geometry: 9N12P, 12N14P, 24N28P, plus skew designs to minimize cogging torque for smooth flight control.

Reenives advantage: Private mould development within 20 days. Over 400 standard tooling sets available for rapid sampling. Free DFM (Design for Manufacturing) analysis with 3D drawing upload.

🛠️ 5-Step Engineer's Selection Guide – Optimizing Your Electric Stator Core

1. Determine electrical frequency & max RPM: For FPV >45k RPM → 0.15mm or 0.20mm laminations to minimize eddy current losses.
2. Calculate torque density & outer diameter: Larger OD improves torque. Reenives provides 2D FEM simulation to validate slot and tooth geometry.
3. Select insulation coating based on operating environment: Epoxy C6 for maritime/agricultural drones; C3 for indoor/light UAVs.
4. Validate stacking factor and mechanical rigidity: Reenives achieves ≥97% stacking factor, reducing core axial length while maximizing flux.
5. Request custom tooling & engineering samples: Private mould supported. Free DFM report with 3D model evaluation (STP/IGES).

📎 Pro engineering tip: Pair Reenives electric stator with N52UH magnets and optimized winding pattern → 15-20% higher efficiency at hover throttle.
