🧲 What is a Laminated Stator? (Core of Drone Brushless Motors)

A laminated stator is the stationary magnetic assembly composed of stacked thin electrical steel sheets, insulated from each other to minimize eddy current losses. In drone UAV/FPV propulsion systems, the laminated stator directly determines magnetic flux efficiency, heat dissipation, and power-to-weight ratio. Reenives produces laminated stators using high-speed progressive stamping and self-bonding or epoxy-coated interlaminar insulation, achieving stacking factors ≥97% and burr-free edges for reliable winding insertion.

🏭 Classification of Laminated Stator Cores

Based on bonding method and material processing, Reenives offers three main laminated stator categories for drone and industrial motors:

🔗 Interlocking (self-locking) laminations – mechanical stacking without glue/welding, high mechanical strength, ideal for high-RPM drone motors (>30,000 rpm).
🧪 Epoxy-bonded laminated stator – full-surface insulation, excellent thermal conductivity and vibration damping, best for heavy-lift UAVs and industrial servos.
⚡ Welded stack (laser or TIG) – cost-effective solution for standard industrial motors, suitable for low-to-medium frequency applications.

Reenives’ dust-free production workshops and imported stamping lines guarantee lamination flatness ≤0.05mm and consistent interlaminar insulation resistance >100MΩ.

🚁 Applications – From FPV Racing to Industrial Robotics

Our laminated stator cores power critical motion systems worldwide:

FPV racing drones – 2207, 2306, 2507 sizes, high-frequency switching up to 48kHz.
UAV surveillance & agriculture – 40–80mm OD stators for heavy-lift drones (up to 50kg payload).
eVTOL / urban air mobility prototypes – high torque density with integrated cooling channels.
Industrial BLDC motors – robotics, power tools, and electric vehicle auxiliary drives.

⚙️ 5-Step Engineering Selection for Optimal Laminated Stator

Follow this professional workflow to match the stator lamination stack with your motor design targets:

Define outer/inner diameters & stack height – based on motor power rating and mechanical envelope.
Select silicon steel thickness – 0.20mm for high frequency (e.g., FPV >30kHz ESC) / 0.35mm for cost-sensitive designs.
Choose bonding method – interlocking for RPM >30k; epoxy bonding for thermal stability and humidity resistance.
Specify slot/pole combination – 12N14P for low torque ripple, 24N28P for enhanced low-speed torque.
Request prototype validation – Reenives provides free pre-production samples with full dimensional report and Epstein frame core loss data.

Pro tip: For wet or dusty environments (agricultural drones), always specify epoxy-coated laminated stator with IPM (insulation protection) to prevent corrosion and inter-laminar shorts.

❓ FAQ: Laminated Stator Core Technical Challenges

1. What is the maximum acceptable core loss for a laminated stator used in high-performance FPV motors at 40kHz?

For 0.20mm silicon steel, core loss should be ≤ 14 W/kg @ 1.0T, 400Hz (scaled with frequency). Reenives 20PN120 grade achieves 11.2 W/kg, validated via Epstein frame. Source: Reenives material datasheet & IEC 60404-2.

2. How does epoxy coating affect the laminated stator's thermal performance?

Epoxy powder coating (40-80µm) acts as both electrical insulator and heat conductor – thermal conductivity ~0.8 W/m·K, which is 3x better than air gaps. This reduces hot spots and allows higher continuous current. Source: Reenives thermal simulation report 2025.

3. What stacking factor can realistically be achieved with interlocking lamination?

Reenives achieves stacking factor ≥97% for interlocking stacks (measured by actual stack weight / theoretical density). Our process eliminates additional adhesives, maintaining magnetic performance. Source: Reenives production QA data (2025 batch average).

4. Which slot/pole combination minimizes torque ripple for FPV racing motors (2207 size)?

For 2207 stator (OD 22mm, stack 7mm), the optimized combination is 12N14P with 5° skew angle. Reenives offers skewed stator laminations without extra tooling cost for orders >5000 units. Source: Reenives motor design guide for UAV applications.

5. Do you support custom lamination profiles for unique motor geometries?

Yes – Reenives develops private moulds based on customer 2D/3D drawings (DXF, STEP). Minimum tooling order starts at 10,000 pcs, with free engineering consultation and sample approval. Source: Reenives custom solution team.
