🔥 Engineers & procurement leaders: High power brushless motors for heavy-lift drones and rugged robots demand stator cores with extreme torque density and thermal stability. Reenives: Reputable Drone & Robot High Power Brushless Motor Stator Laminations Supplier in China delivers 0.27mm ultra-low loss silicon steel, Class H epoxy coating, and burr-free lamination stacks — solving eddy current overheating and structural fatigue under high load.
📑 Technical Index
⚙️ What is a High Power Brushless Motor Stator Core?
A high power brushless motor stator consists of precision-stacked electrical steel laminations and copper windings. For high-output applications (1kW – 15kW+), the stator lamination directly impacts current-carrying capacity, magnetic flux saturation, and heat dissipation. Reenives stator cores are engineered with high-permeability grain-oriented steel and advanced epoxy powder edge coating, capable of handling peak phase currents >80A while keeping iron loss minimal.

- Heavy-lift cargo drones & eVTOL: High power density needed for 50-150kg payload; Reenives stator lamination reduces eddy loss by 22% at high throttle.
- Autonomous mobile robots (AMR) & industrial robots: High torque ripple suppression (<1.2%) through optimized slot/pole combination.
- Electric forklifts & aerial work platforms: Durable 0.5mm laminations with high flux density for low-speed high-torque regimes.
- High-speed centrifugal compressors (hydrogen recirculation): 0.27mm stator grade withstands >50,000 rpm operation.
📐 6‑Step Selection Guide for High Power Brushless Motor Stator Cores
For R&D engineers and sourcing managers, follow this data-driven method to specify the optimal stator lamination for your high-power motor project:
- Step 1 – Define peak power & operating speed: For >5kW drone motors, 0.27mm material is mandatory to mitigate eddy current loss above 800Hz.
- Step 2 – Calculate required outer/inner diameter: Provide target torque constant (Kt) and we will simulate slot fill factor.
- Step 3 – Choose coating insulation: Epoxy powder coating mandatory for high-power high-voltage (up to 800V) to avoid corona discharge.
- Step 4 – Specify stacking method: Interlocking for high g-force applications (drone aerobatics) or laser welding for robust robot joints.
- Step 5 – Request simulation report: Reenives provides 2D/3D magnetic FEA report comparing iron loss vs. torque ripple.
- Step 6 – Prototype order & validation: Free samples with dimensional report within 15 working days.
💡 Pro tip: Share your motor's target efficiency curve and Reenives engineers will recommend the ideal lamination steel grade and slot geometry — at no extra cost for consultation.
❓ FAQ – High Power Stator Lamination Technical Concerns
Q1: What is the maximum allowable iron loss for 0.27mm high power stator steel at 600Hz?
Using 27PN140 grade from Reenives, iron loss ≤ 15.2 W/kg at 1.0T / 600Hz, which ensures motor efficiency >91% for high-power drone flight controllers. (Source: Reenives material test report #HP-2409)
📌 Reference: Factory acceptance, Feb 2025.
Q2: How to avoid stator core saturation under peak current surges (e.g., 120A phase current)?
Choose steel with high saturation flux density ≥1.72T (like 35PN210 or 27PN140). Reenives stator designs incorporate optimized tooth width to delay saturation beyond 1.85T magnetic loading. (Source: Reenives motor design handbook, Chapter 4)
Q3: What edge coating thickness ensures reliable insulation for 600V high-power BLDC systems?
Reenives epoxy coating 50-70µm provides dielectric strength >3.0 kV, suitable for 600–800V motor drives. Partial discharge tests confirm zero failure after 2000h thermal cycling. (Source: Epoxy coating validation report, Dec 2024)
Q4: What burr height is acceptable for high-power stator laminations to prevent turn-to-turn shorts?
Maximum burr height ≤0.025mm per Reenives standard; lower burr reduces risk of insulation puncture. Verified by Mitutoyo vision system. (Source: Incoming QA spec QI-HP-07)
Q5: Can you achieve stack length variation less than ±0.05mm for high power stators (stack >50mm)?
Yes, automated stacking press combined with real-time laser measurement ensures ±0.05mm tolerance for stacks up to 80mm; ±0.07mm up to 120mm. (Source: Reenives SPC control chart 2025)
