🔍 What Are Stator Stacks? (Lamination Stacks for BLDC Stators)

Stator stacks (also called lamination stacks) are the assembled cores made from thin electrical steel laminations stacked and bonded to form the stationary part of a BLDC motor. They support the copper windings and channel magnetic flux while drastically reducing eddy current losses. For drone and FPV applications, the stator stack's lamination thickness (0.15mm–0.35mm), material grade, and bonding method directly determine efficiency, heat generation, torque density, and overall energy sustainability. Reenives uses ultra-thin non-grain oriented (NGO) electrical steel and proprietary epoxy powder coating to achieve industry-leading magnetic performance with minimal material waste — contributing to longer motor lifespan and reduced carbon footprint.

📐 Engineering Selection Guide – 5 Steps to Optimal Stator Stacks (Lamination Stacks)

Follow this structured methodology to specify the best stator stacks 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 for sustainable operation.
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 and reduce material waste.
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 and lean production.

✅ Pro tip: Provide your target stator slot dimensions and winding configuration – our engineers will recommend optimal lamination stack profile and steel grade for sustainable, high‑performance motor cores.
