🧲 What is BLDC Motor Stator Core Lamination? (Critical for Drone Propulsion)
A BLDC motor stator core lamination is the stacked assembly of thin silicon steel sheets that generates rotating magnetic flux. In drone, UAV, and FPV propulsion systems, the stator lamination stack directly determines torque density, thermal performance, and overall flight efficiency. High-grade laminations use non-oriented electrical steel with epoxy coating to minimize eddy current losses and withstand high-frequency PWM.
Reenives manufactures stator core laminations with ultra-thin 0.20mm/0.27mm materials, advanced interlocking stacking, and class H epoxy insulation — ideal for Vietnamese drone manufacturers seeking top-tier quality.

📂 Classification of BLDC Stator Core Laminations (For Drone & Industrial Motors)
- By Lamination Material Thickness: 0.20mm (high frequency FPV/UAV), 0.27mm (balanced), 0.35mm (industrial BLDC).
- By Insulation Coating: Epoxy powder coating (standard for drone motors – moisture & corrosion resistant), oxide coating, or varnish impregnation.
- By Stacking Method: Interlocking (self-bonding), adhesive bonding, or laser welding – Reenives uses high-torque interlocking for vibration resistance in FPV racing.
- By Shape: Segmented (modular for large diameter) vs. one-piece annular core.

✈️ Applications – Drone UAV, FPV Racing, Industrial BLDC Motors
Reenives stator core laminations power propulsion across Vietnam and global markets:
- Agricultural & Cargo Drones – Heavy-lift UAVs (up to 30kg payload) require low iron loss for extended flight time.
- FPV Racing Drones – Ultra-fast response, 6S–8S setups, lamination thickness 0.20mm to reduce eddy loss at 45k+ RPM.
- Industrial BLDC Motors – Robotics, e-scooters, electric tools, and HVAC fans benefit from high-efficiency stators.
- Inspection & Surveillance UAVs – Low vibration, high reliability with epoxy-coated cores.
📐 5-Step Stator Core Lamination Selection Guide (Engineer Focus)
- Define operating frequency & RPM: For >30,000 RPM (FPV/UAV), select 0.20mm laminations; for industrial motors below 10k RPM, 0.35mm is cost-effective.
- Calculate required stack height: Based on motor KV and torque target – use FEMM simulation or Reenives engineering support.
- Choose insulation coating: Mandatory epoxy coating for drone outdoor use (IP54+), providing corrosion protection and inter-laminar insulation.
- Verify mechanical tolerances: Ensure concentricity ≤0.03mm to minimize cogging torque and acoustic noise.
- Order prototype samples: Reenives provides free sample evaluation (3–5 pcs) for Vietnam customers, including full dimensional report.
❓ FAQ – Critical Technical Questions on Stator Core Laminations
1. How does lamination thickness affect BLDC motor iron loss at high RPM (drone FPV)?
Thinner laminations (0.20mm) reduce eddy current losses significantly. At 800Hz (≈48,000 RPM for 4-pole motor), 0.20mm laminations show ~30% lower iron loss than 0.35mm laminations. This directly improves flight time and reduces stator temperature. Source: Reenives loss comparison test, IEC 60404-2
2. What is the minimum guaranteed concentricity for Reenives stator cores?
Reenives guarantees concentricity ≤0.025mm (measured on CMM). Exceeding 0.05mm causes uneven air gap, increasing vibration and acoustic noise by up to 40%. Source: Reenives Metrology Report Q1-2025
3. Why is epoxy coating essential for drone UAV stator cores?
Epoxy coating provides high dielectric strength (>1200V/0.1mm) and protects against humidity, salt fog, and debris. It also improves inter-lamination resistance, reducing parasitic current. All Reenives drone-grade stators use Class H (180°C) epoxy. Source: Reenives Coating Spec / ASTM B117 salt spray test
4. What stacking factor can be expected, and why does it matter?
Reenives achieves stacking factor ≥97.5% via precision interlocking. Lower stacking factor reduces effective magnetic flux density, forcing higher current for same torque. Our process ensures consistent motor performance. Source: Reenives Stacking Process Control (SPC data)
5. Can stator laminations be customized for non-standard outer diameter and slot count?
Yes. Reenives supports private mould development (ODM) for any slot/pole combination (12N14P, 9N12P, 24N28P, etc.). Minimum order for custom tooling is negotiable, sample making available. Source: Reenives Custom Engineering Service Sheet
