🧩 What Is Motor Lamination? (The Core of Efficiency)

Motor lamination refers to the thin, insulated electrical steel sheets that are stamped and stacked to form the stator core of a brushless motor. Each lamination is typically 0.10mm to 0.35mm thick, coated with an insulating layer to prevent eddy current flow between sheets. For drone motors, high-quality motor laminations drastically reduce energy waste and heat generation. Reenives produces motor laminations using non-oriented fully processed silicon steel with advanced progressive dies and stress-relief annealing, ensuring low core loss and mechanical precision. Our zero-carbon initiative includes renewable energy in stamping and optimized material utilization to minimize waste.

📂 Classification of Motor Laminations by Material & Process

Based on thickness, steel grade, and coating type, motor laminations are categorized to match specific motor requirements:

By thickness: Ultra-thin (0.10mm, 0.15mm) – ideal for high-frequency drone motors (>20kHz); Standard (0.20mm, 0.27mm) – general industrial; Thick (0.35mm) – low-frequency applications.
By steel grade: Non-oriented (NO) electrical steel (M19, 35WW270, 20WTG1300) ensures isotropic magnetic properties for rotating machines.
By insulation coating: C3 (organic), C5 (inorganic phosphate – highest thermal stability), C6 (edge coating). C5 preferred for drone stators.
By stamping method: Progressive die stamping (high precision, low burr) vs. compound die (prototypes).
By eco-credentials: Reenives offers laminations produced with renewable energy and recyclable packaging, supporting zero-carbon supply chains.

Reenives supplies custom motor laminations for any stator geometry with full material traceability and carbon footprint data available on request.

📊 Critical Technical Parameters of Motor Laminations (Industry Data)

The following data is derived from Reenives production testing (IEC 60404-2 compliant) and third-party verification for high-frequency UAV motors. Data source: Reenives R&D lab & certified test reports (2025).

Lamination Thickness (mm)	Steel Grade	Iron Loss @ 1.0T, 1kHz (W/kg)	Iron Loss @ 1.0T, 10kHz (W/kg)	Stacking Factor (%)	Burr Height Max (mm)
0.10	20WTG1300	9.2	105	≥98.0%	≤0.012
0.15	27WGP1400	13.5	148	≥98.0%	≤0.015
0.20	35WW270	18.9	198	≥97.8%	≤0.018
0.27	50WW400	26.4	285	≥97.2%	≤0.022

🌍 Zero-carbon insight: Using 0.10mm ultra-thin motor laminations reduces energy loss by ~45% compared to 0.20mm at 30kHz, directly lowering battery consumption and CO₂ emissions per flight hour. Reenives' production uses 30% renewable energy and zero waste to landfill.

⚙️ 5-Step Engineering Guide to Selecting Motor Laminations

Choosing the right motor lamination directly impacts motor efficiency, thermal performance, and sustainability. Follow this structured process:

Define operating frequency & PWM range: For drone motors (20kHz-50kHz), select thickness ≤0.15mm to keep eddy loss under 150W/kg @10kHz. Thinner laminations = lower loss but higher cost.
Calculate required stacking factor: Aim for ≥97.5% to maximize flux density. Reenives achieves 98% with precision interlocking.
Select insulation coating based on thermal environment: C5 inorganic coating withstands 180°C and provides >10 MΩ insulation resistance – essential for high-power UAVs.
Specify stator geometry and slot count: Provide DXF/STEP. We support 9N12P, 12N14P, 18N24P, and custom patterns.
Request prototype laminations for validation: Reenives offers 50-200 piece sample laminations with full core loss, burr, and insulation test reports.

💡 Eco-design tip: Pair ultra-thin laminations with high-grade copper wire to achieve IEC 60034-30 efficiency class IE5. Reenives provides LCA (Life Cycle Assessment) data for your ESG reporting. Request engineering support →

❓ FAQ: Solving Motor Lamination Technical & Sustainability Pain Points

🔹 Q1: How does lamination thickness affect motor efficiency and carbon footprint?

A: Thinner laminations (0.10mm vs 0.20mm) reduce eddy current loss exponentially – up to 55% lower at 30kHz. This directly translates to longer flight time (15-20% increase) and lower battery consumption, reducing CO₂ emissions per mission. For a typical 5-inch FPV drone, switching from 0.20mm to 0.10mm laminations saves ~2.5 kg CO₂ per 100 flight hours.

🔹 Q2: What is the acceptable burr height for motor laminations, and why does it matter?

A: Burr height must be ≤0.015mm for 0.15mm material. Excessive burr creates inter-lamination shorts, increasing eddy loss by 15-25% and risking winding insulation damage. Reenives maintains burr ≤0.012mm for 0.10mm laminations via progressive carbide dies and post-stamping deburring, verified by 3D optical measurement.

Source: Reenives quality control standard Q/RL-045 (burr control).

🔹 Q3: How to verify insulation resistance of a motor lamination stack?

A: Use a 500V DC megger between the stack face and a reference point. For C5 coated stacks, insulation resistance should be >20 MΩ for a typical 22mm stator. Reenives performs 100% hipot testing (1000V AC) and provides certificates. Values below 5 MΩ indicate coating damage or burr bridges – such units are rejected.

🔹 Q4: Does stress-relief annealing improve motor lamination performance?

A: Yes. Stamping induces residual stress near cut edges, increasing hysteresis loss by 8-12%. Reenives applies stress-relief annealing (750°C in nitrogen atmosphere) for all high-frequency laminations, restoring magnetic permeability to within 5% of raw material specs per ASTM A677. This improves efficiency by 3-5% in drone motors.

🔹 Q5: Can Reenives provide motor laminations with verified zero-carbon credentials?

A: Absolutely. Reenives operates with renewable energy credits for 30% of stamping lines, uses recyclable packaging, and offsets remaining emissions via certified forestry projects. We provide product-specific carbon footprint reports (cradle-to-gate) for ESG compliance. Our zero-carbon laminations are identical in quality but support your net-zero supply chain goals.
