What is FPV Motor Stator Lamination? Core Component for High-Speed BLDC Motors

A FPV motor stator lamination is a stack of ultra-thin silicon steel sheets that form the stationary part of a brushless DC motor. In drone UAV and racing FPV applications, stator laminations directly influence torque density, heat dissipation, and overall power-to-weight ratio. High-quality laminations reduce eddy current losses and hysteresis, enabling motors to sustain high RPM without thermal runaway. At Reenives, each stator core is precision-stamped using imported progressive dies, with optional epoxy powder coating for superior insulation and corrosion resistance.

Stator Lamination Classification & Material Grades (Engineer-Focused)

Based on magnetic properties and application requirements, Reenives offers three primary stator core categories:

🏁 Ultra-High Frequency Series (FPV Racing / Small Drones) – 0.15mm – 0.2mm thickness, 35WW270 or 35ZH130 grade, low core loss < 8 W/kg @ 1.0T, 400Hz. Ideal for 2006-2306 stator size.
🛸 Industrial UAV & eVTOL Series – 0.27mm – 0.35mm, high saturation flux density (1.7T), high mechanical strength, epoxy insulated coating, suitable for heavy-lift and long-endurance drones.
⚙️ General BLDC Automation Series – 0.35mm – 0.5mm, cost-effective for servo motors, factory automation, and e-scooters, with balanced performance and price.

Custom private mould development supported: any slot/pole combination (12N14P, 9N12P, 24N28P) and custom stack heights from 5mm to 60mm.

Applications: From FPV Drone Racing to Industrial Servo Drives

Our stator laminations are engineered for scenarios demanding high efficiency and reliability:

✈️ FPV Racing / Cinematic Drones – 2004 to 2810 stator size, minimal cogging torque, high KV output for instantaneous throttle response.
🚁 UAV Propulsion (Agriculture, Mapping, Delivery) – Large-diameter pancake style stators with high torque for 6-12S LiPo systems.
🏭 Industrial BLDC Motors (Automation, Robotics, Medical Devices) – Low-noise, high-reliability stator cores for continuous operation.
🚲 Electric Mobility (e-scooters, e-bike hub motors) – Rugged stator stamping suitable for high-torque direct drive.

5-Step Engineering Selection Guide for Stator Lamination (Custom Solutions)

Step 1 – Define Motor Power & RPM Range
For FPV motors <200W, recommend 0.15mm laminations. For industrial 500W+, 0.27mm-0.35mm.

Step 2 – Choose Steel Grade based on frequency
High-speed drones (40kHz PWM) → thin gauge (0.15-0.20mm). Low-speed high-torque → 0.35mm.

Step 3 – Slot/Pole Combination & Stack Height
12N14P for FPV, 24N28P for UAV heavy-lift. Stack height: stator ID/OD optimization.

Step 4 – Insulation & Coating Requirements
Epoxy powder coating increases voltage breakdown strength (up to 3kV) and reduces winding shorts.

Step 5 – Private Mould & Sample Validation
Reenives offers sample prototyping (3-7 working days) and advanced simulation to match your dynamic performance targets.

Frequently Asked Questions (FPV Motor Stator Core Technical Deep-Dive)

❓ 1. What is the optimal stator lamination thickness for an FPV racing motor targeting 6S 2400KV?

For FPV 6S high-KV motors (2306/2207 size), Reenives recommends 0.15mm or 0.20mm non-grain-oriented silicon steel (35ZH130 grade). Thin laminations reduce eddy current losses at high switching frequencies (30-40kHz), improving efficiency by 8-12% compared to standard 0.35mm stacks. Our test data shows a 11.5°C lower winding temperature under sustained full throttle. (Source: Reenives motor dyno test report, May 2025)

❓ 2. How does epoxy powder coating affect stator performance and assembly?

Epoxy coating (min. 40µm thickness) increases inter-lamination resistance > 500 MΩ, prevents rust in high-humidity drone flights, and provides excellent adhesion for windings. Reenives' imported coating line ensures uniform layer without altering slot geometry. For UAV stators, coating extends product lifetime in agricultural spraying drones. (Source: Reenives internal QC standard RLV-EP-2402)

❓ 3. What is the maximum stack height and outer diameter you can manufacture for high-power industrial BLDC motors?

Reenives supports stator lamination OD from 12mm to 250mm, stack height from 5mm to 120mm with single-piece or segmented stacking. For industrial eVTOL motors, we have delivered custom 250mm OD stators with 100mm stack (0.27mm laminations). The maximum weight per stator core can reach 7.2kg. Custom tooling for large diameters available with 4-week lead time. (Source: Reenives engineering database 2025)

❓ 4. Can Reenives supply stator laminations with notches for temperature sensors or PCB mounting?

Yes, during private mould development we integrate precise notches, slots or alignment features per your mechanical drawing. More than 60% of our industrial drone customers adopt special-cut stators for thermal sensor integration. (Source: Customer project portfolio, Reenives 2024-2025)

❓ 5. What certification and quality assurance do you provide for export stator cores?

All our stator laminations are produced under IATF 16949 quality management framework (applicable to automotive/BLDC standards). We supply material certificates (EN 10204 3.1), RoHS & REACH compliance, and optional third-party inspection reports (SGS, TÜV). Our export qualifications cover 40+ countries including USA, Germany, Brazil, and Korea. (Source: Reenives Quality Dept & Export License 2025)
