An FPV motor stator core is the stationary laminated magnetic structure of a brushless motor designed for first-person view racing and freestyle drones. These motors prioritize extreme power-to-weight ratio, instant throttle response, and the ability to sustain RPM exceeding 40,000. The stator core — with ultra-thin laminations, optimized slot geometry, and high stacking factor — is the critical component that enables this performance.

Reenives manufactures high-quality FPV motor stator cores using non-grain oriented silicon steel (0.15-0.20mm) with advanced C5 epoxy coating — achieving ≤7.5 W/kg core loss and up to 98.6% stacking factor for maximum thrust and thermal efficiency.

Reenives offers FPV motor stator cores in multiple configurations to meet diverse racing and freestyle requirements:

• By Motor Size: 2207 (5-inch racing/freestyle), 2306 (high-torque 5-inch), 2205 (lightweight 5-inch), 2507 (long-range), 2808 (6-inch/heavy-lift).
• By Slot/Pole Config: 12N14P (DLRK - most common, smooth and quiet operation), 9N12P (ultra-light racing), 18N20P (high torque density).
• By Material Thickness: 0.15mm (extreme high-RPM racing >50,000 RPM, 6S), 0.20mm (standard high-performance FPV, 4-6S), 0.27mm (budget/3-4S builds).
• By Insulation Coating: C5 epoxy powder coating (Class H, 180°C) with >2000V dielectric strength; thin-film coating (30-40μm) for tight slot geometries in compact stators.
• By Stacking Method: Epoxy bonding (essential for 0.15mm ultra-thin laminations); interlocking self-bonding (0.20mm+).

💡 Reenives specialty: private mould development for custom FPV stator geometries — including skew designs that reduce cogging torque by 30-50% for smoother freestyle control and race-winning throttle response.

All parameters validated by Reenives R&D center (ISO 9001:2025 certified) and third-party testing per IEC 60404-2. Reenives 0.15mm ultra-thin FPV stators deliver 30-38% lower core loss than 0.20mm stacks, translating to 8-12°C lower operating temperature and 7% more thrust at full throttle — verified on independent 6S dyno testing.

Reenives FPV motor stator cores power critical applications across multiple sectors:

• FPV Racing Drones: 2207, 2306 stators with 0.15mm laminations for 45,000+ RPM and 92%+ peak efficiency — delivering race-winning thrust-to-weight ratios.
• Freestyle & Cinematic Drones: Smooth, responsive torque with reduced cogging for fluid maneuvers and stabilized footage — 0.20mm laminations offer the ideal balance of performance and cost.
• Long-Range FPV Drones: 2507, 2808 stators with 0.20mm laminations optimized for endurance and efficiency at moderate RPM.
• Industrial Inspection Drones: Reliable, high-performance stators for professional UAV applications.
• FPV Fixed-Wing Racers: Lightweight stators for wing racing with high efficiency at sustained high speeds.

1. Define prop size and battery voltage: For 5-inch FPV with 4-6S LiPo, select 2207 or 2306 motor size. For 6S racing (>40,000 RPM), 0.15mm laminations are essential.
2. Choose lamination material thickness: 0.15mm for premium 6S racing performance (lowest core loss, 7% more thrust); 0.20mm for standard 4-6S freestyle; 0.27mm for budget 3-4S builds.
3. Select slot/pole combination: 12N14P (DLRK) for balanced torque/speed and smooth operation — most common for 5-inch FPV; 9N12P for ultra-light racing.
4. Specify insulation and stacking method: Epoxy bonding for 0.15mm ultra-thin laminations; interlocking for 0.20mm+; thin-film coating (30-40μm) for tight slot geometries.
5. Request samples and validation: Reenives delivers first-article inspection reports (FAI) and material certificates. Prototype FPV stator samples ready in 7-10 days after design approval.
