1. What Defines a 6S Brushless Motor Stator Lamination?

A 6S Brushless Motor operates at nominal 22.2V (peak 25.2V) with significantly higher current and RPM than lower-voltage counterparts. The stator lamination stack must withstand higher magnetic flux density (up to 1.7T) and switching frequencies (16–48kHz) without excessive eddy current losses. Reenives uses 0.15mm ultra-thin or 0.20mm high-grade silicon steel (27GP120 / 35W270) with advanced epoxy powder coating. This combination delivers 30-38% lower core loss compared to standard 0.27mm stacks, ensuring cooler operation and longer motor life at 6S power levels.

2. Classification by Lamination Thickness & Steel Grade

📏 0.15mm Grade27GP120 – Extreme high-frequency (50k+ RPM), lowest eddy loss for competitive racing

📏 0.20mm Grade35W270 – Best balance of performance & cost for 6S freestyle/heavy-lift

🛡️ CoatingEpoxy powder (C7) – mandatory for 6S to prevent corona discharge & moisture

🔗 StackingInterlocking (high vibration) / Bonded (minimum core loss)

3. Technical Specifications (IEC & Reenives 6S Dyno Data)

Stator OD range: 22mm – 85mm (optimized for 6S power levels)
Lamination thickness: 0.15mm / 0.20mm ±0.005mm
Core loss @25kHz (P0.5/25k): ≤ 34 W/kg (0.15mm) → 38% lower than 0.27mm standard
Saturation flux density (B50): 1.69T (linear torque up to 50A phase current)
Insulation resistance (epoxy): >120 MΩ @500V (critical for 6S arcing prevention)
Stack flatness: ≤0.04mm over 12mm stack height
Burr height: ≤0.02mm (prevents winding shorts under high vibration)
Max recommended RPM: 75,000 (0.15mm) / 60,000 (0.20mm)

5. Engineering Selection Guide for 6S Brushless Motor Stators

Define target KV & voltage: 6S (22.2-25.2V) – higher KV requires thinner laminations to reduce eddy loss.
Select lamination thickness: 0.15mm for racing & high-RPM (>50k), 0.20mm for freestyle & heavy-lift.
Coating requirement: Epoxy coating is mandatory for 6S to prevent electrical breakdown and moisture ingress.
Stacking method: Interlocking for motors subject to crashes/impact; bonded core for absolute minimum loss in competition builds.
Sample validation: Reenives provides core loss report + thermal imaging under 6S load within 7-10 days for prototypes.

6. FAQ – 6S Brushless Motor Stator Lamination Engineering

❓ Q1: Why is 0.15mm lamination critical for high-performance 6S racing motors?

Answer: 6S motors run at higher PWM frequencies (24-48kHz) and RPM. 0.15mm laminations reduce eddy current loss by 30-38% compared to 0.20mm, translating to 8-12°C lower operating temperature and 7% more thrust at full throttle — decisive in competitive racing.

❓ Q2: Can I use standard 0.27mm laminations for a 6S drone motor?

Answer: Not recommended. 0.27mm laminations will cause excessive core loss at 6S voltages, leading to thermal runaway and reduced flight time. Always use ≤0.20mm for reliable 6S operation.

❓ Q3: Does Reenives offer segmented stator laminations for easier winding on 6S motors?

Answer: Yes. Segmented stacks simplify automated winding and improve slot fill factor to 93%, essential for 6S high-current windings. Available for all racing and industrial geometries.

❓ Q4: What insulation rating does your epoxy coating provide for 6S high-voltage environment?

Answer: Reenives epoxy coating (40-50µm) is rated for 500V dielectric strength (per UL 1446), preventing corona discharge and phase-to-phase shorts even under 6S peak voltage 25.2V with safety margin.

❓ Q5: Can you develop custom 6S stator tooling for non-standard sizes (e.g., 2510 or 3115)?

Answer: Absolutely. With 100+ R&D patents, Reenives develops custom progressive dies for unique 6S stator geometries. Lead time: 25-35 days for tooling, samples available.
