Electric Motor Laminations for High‑Efficiency UAV & FPV Motors
⚡ Reenives: Leading FPV UAV Drone Electric Motor Laminations Supplier in Europe

🔍 What Are Electric Motor Laminations? (Stator & Rotor Cores)

Electric motor laminations are thin sheets of electrical steel stacked and bonded to form the stator and rotor cores of BLDC motors. Each lamination is insulated from its neighbors to minimize eddy current losses — a critical factor for high-speed drone motors. For FPV and UAV applications, lamination thickness, material grade, and coating directly determine efficiency, torque ripple, and thermal stability. Reenives uses ultra-thin non-grain oriented (NGO) electrical steel (0.20mm / 0.27mm) and proprietary epoxy powder coating to achieve industry-leading magnetic performance.

📐 Engineering Selection Guide – 5 Steps to Optimal Laminations

Follow this structured methodology to specify the best electric motor laminations for your BLDC design (based on Reenives application engineers' recommendations):

1. Step 1 – Define motor electrical frequency & RPM range: For >1 kHz (FPV racing), select 0.15–0.20mm laminations. For industrial UAV (<800 Hz), 0.27–0.35mm is cost-effective.
2. Step 2 – Calculate core loss budget: Use iron loss curves (provided by Reenives) to avoid thermal runaway. Target total core loss <5% of rated power.
3. Step 3 – Choose insulation coating type: Epoxy powder coating (Reenives standard) offers best thermal stability and dielectric strength for high-voltage ESCs.
4. Step 4 – Specify stacking factor & bonding method: Request ≥97% stacking factor with epoxy bonding to maximize magnetic flux.
5. Step 5 – Prototype & validate: Order custom samples (5-7 days), perform back-EMF and temperature rise tests. Reenives supports private mould development with low MOQ.

✅ Pro tip: Provide your stator slot dimensions and target Kv rating – our engineers will recommend optimal lamination tooth profile and material grade.
