A DIY stator stack is a pre-laminated silicon steel core designed for motor enthusiasts and engineers to wind their own coils — enabling custom KV ratings, optimized torque curves, and tailored performance for UAVs, FPV drones, and experimental BLDC motors. Unlike generic stators, DIY-focused stacks come with consistent lamination quality (0.20mm/0.35mm), precise slot geometries, and epoxy insulation ready for hand-winding .

Reenives manufactures DIY stator stacks using high-permeability electrical steel with advanced epoxy powder coating — reducing eddy current losses and providing a durable, high-temperature surface for winding .

Reenives offers DIY stator stacks in multiple configurations to suit different motor building needs:

• By Slot/Pole Config: 9N12P (high RPM), 12N14P (balanced torque/speed), 18N24P (high torque density) .
• By Material Thickness: 0.20mm (high-frequency FPV / racing) and 0.35mm (general UAV / industrial).
• By Insulation Coating: Epoxy powder coating (Class H, 180°C) with ≥1800V dielectric strength .
• By Stacking: Interlocking or epoxy-bonded for consistent stacking factor ≥97% .

💡 Reenives specialty: private mould development for custom slot geometries — perfect for one-off DIY projects or small-batch production .

All values derived from Reenives in-house R&D lab and third-party testing per IEC 60404-2 and ASTM A912. Critical for DIY builders targeting specific KV and efficiency .

Reenives DIY stator stacks enable custom motor building for:

• FPV Racing Drone Motors: 2207, 2306, 2507 stators — rewind for custom KV (e.g., 1900KV → 2400KV) .
• Custom UAV Propulsion: Long-endurance builds requiring specific torque and efficiency curves.
• Gimbal & Servo Motors: Ultra-smooth torque with custom winding patterns.
• Experimental & Open-Source Projects: PCB motors, 3D-printed frames, and education .

1. Choose your stator stack: Select OD and slot/pole configuration based on your target motor size and KV (e.g., 2207 for 5-inch FPV) .
2. Select lamination thickness: 0.20mm for high-frequency racing (40-80kHz PWM) or 0.35mm for general UAV use .
3. Determine winding pattern & turn count: Reference original turn count or calculate using target KV (e.g., KV ∝ 1/turns) .
4. Wind carefully: Use appropriate magnet wire gauge (e.g., 17-18 AWG for typical FPV motors). Apply epoxy after each layer to prevent vibration damage .
5. Test and validate: Measure resistance (e.g., 7-8Ω low coil), perform hipot test, and verify with ESC before flight .
