🔍 What is a Stator Core? (Core Role in BLDC Motors)

A stator core is the stationary electromagnetic component in a brushless DC (BLDC) motor, consisting of thin silicon steel laminations stacked and bonded/insulated. It houses the windings and generates a rotating magnetic field that interacts with rotor magnets. For UAVs, FPV drones and high-rpm industrial motors, the stator core's magnetic properties, lamination thickness, and insulation directly determine efficiency, heat generation, and power density. Reenives uses imported high-grade non-grain oriented (NGO) electrical steel and precision stamping dies to achieve ultra-low hysteresis losses.

📐 Engineering Selection Guide – 5 Steps to Perfect Stator Core

Follow this structured approach to specify the optimal stator core for your BLDC motor design (based on Reenives application engineers’ best practices):

1. Step 1 – Define motor power & speed range: Calculate required torque and Kv rating → determine stator outer diameter and stack height.
2. Step 2 – Choose lamination material thickness: For high-frequency (>1kHz) FPV motors → 0.20mm or 0.15mm; industrial UAV → 0.27~0.35mm.
3. Step 3 – Evaluate iron loss budget: Use core loss simulation (we provide JMAG support) to avoid thermal runaway.
4. Step 4 – Insulation & coating specification: Epoxy powder coating (Reenives proprietary line) ensures high dielectric strength & corrosion resistance.
5. Step 5 – Prototype & validation: Order custom samples, test back-EMF, efficiency, and temperature rise. Reenives supports private mould development and fast sampling (5-7 days).

✅ Pro tip: Provide your target winding scheme and slot dimensions, Reenives engineers will recommend the best lamination stacking factor and tooth profile.
