🔩 What is Motor Stamping? (Stator Laminations for BLDC Motors)

Motor stamping refers to the precision blanking and stacking of thin electrical steel sheets to form a stator core. In drone UAV/FPV brushless motors, the quality of stamping directly determines magnetic flux density, heat dissipation, and efficiency. Reenives uses high-speed progressive dies and 0.20mm / 0.35mm non-grain oriented silicon steel to produce laminations with burr heights below 0.02mm, ensuring smooth assembly and reduced iron losses.

🏭 Classification of Motor Stamping Laminations

Based on stamping method and post-processing, Reenives offers three primary categories for UAV and industrial motors:

⚡ Single-blanking stamping – economical for large prototypes, moderate precision.
🔁 Progressive die stamping (high-volume) – micron-level alignment, excellent for mass production (10k+ units/day).
🧪 Interlocking self-bonding stamping – mechanical stacking without welding or glue, ideal for high-RPM drone motors (e.g., 30000 RPM).

Reenives’ imported stamping press lines (capacity up to 400 strokes/min) combined with in-die insulation coating achieve superior consistency for Polish customers requiring tight DIN standards.

⚙️ 5-Step Guide to Select the Right Motor Stamping for Drone Motors

Follow this engineering workflow to optimize stator performance and motor reliability:

Identify motor dimensions: Outer diameter (OD), inner diameter (ID), and stack height – match your winding scheme.
Specify lamination material: 0.20mm for high-frequency (>30kHz) drone ESCs; 0.35mm for cost-sensitive designs.
Choose stamping method: Progressive die for volume >10k pcs/month; single-stage die for prototyping.
Define insulation & bonding: Epoxy coating for IP protection; self-bonding for ultra-high RPM.
Request sample validation: Reenives provides free pre-production samples with full dimensional report + core loss curve.

Pro tip: Ask for burr direction and stacking alignment markers – our stamping guarantees consistent magnetic orientation, reducing torque ripple by up to 18%.

❓ FAQ: Motor Stamping Technical Challenges & Solutions

1. What is the maximum acceptable burr height for high-efficiency drone motor stamping?

According to Reenives QC standard, burr height must be ≤ 0.02mm (20µm). Burrs beyond this increase inter-laminar short circuits and eddy current loss. Our progressive dies guarantee <0.015mm typical. Source: Reenives stamping process control manual & IPC-A-610.

2. How does epoxy coating affect motor stamping stack performance?

Epoxy powder coating provides electrical insulation between laminations, preventing parasitic currents. It also enhances corrosion resistance (salt spray test >96h) and heat transfer. Reenives coating thickness 40-80µm withstands 2000V dielectric test. Source: Reenives material data sheet & ASTM B117.

3. What stacking factor can be achieved with interlocking stamping?

Our self-bonding interlocking process achieves stacking factor ≥97%, comparable to glued stacks, but with better mechanical strength for high-vibration drone applications. Verified by weight/volume method. Source: Reenives production test report 2025.

4. Which slot/pole combination reduces torque ripple for FPV racing motors?

For 2207/2306 stator size, the optimal combination is 12N14P (12 slots, 14 poles) with skewed stator stamping option. Reenives offers skewing without extra tooling cost for volumes >5000 pcs. Source: Reenives drone motor design guide.

5. Do you support custom lamination profile for unique motor geometry?

Yes, Reenives develops private moulds based on customer drawings (DXF/STEP). Minimum order for custom stamping tooling starts at 10,000 units, with free engineering review and prototype samples. Source: Reenives sales engineering team.
