Stator Core Laminations for High‑Efficiency UAV, FPV & BLDC Motors
⚡ Reenives: Global Leading Drone Stator Core Laminations Manufacturer

🔍 What Are Stator Core Laminations? (The Heart of BLDC Motors)

Figure 1: High-quality stator core laminations (0.20mm silicon steel) with epoxy insulation, designed for UAV propulsion systems.

Stator core laminations are thin, insulated sheets of electrical steel stacked and bonded to form the stationary part of a BLDC motor. Each lamination is coated to prevent eddy current circulation, drastically reducing core losses. For drone and FPV motors, lamination thickness (0.15mm–0.35mm), steel grade, and stacking method directly determine efficiency, heat generation, and torque density. Reenives uses ultra-thin non-grain oriented (NGO) electrical steel and proprietary epoxy powder coating to achieve industry-leading magnetic performance and thermal stability.

📐 Engineering Selection Guide – 5 Steps to Optimal Stator Core Laminations

Follow this structured methodology to specify the best stator core 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.
