⚡ Motor engineers & procurement managers in Turkey: Is your FPV or UAV motor struggling with overheating, poor torque response, or short flight times due to excessive core losses? The solution starts with premium 0.2mm laminated silicon steel. Reenives delivers ultra-thin laminations that slash eddy current losses by up to 22%, increase magnetic flux density, and enable higher continuous power. As Reenives: Top1 0.2mm Drone FPV UAV Motor Stator Rotor Core Laminated Silicon Steel Supplier in Turkey, we combine Japanese-grade material, advanced stamping, and fast shipping to Istanbul, Ankara, and beyond — helping you build next‑gen brushless motors.

🔍 What is 0.2mm Laminated Silicon Steel for Stator/Rotor Cores?

Laminated silicon steel refers to thin electrical steel sheets stacked to form the stator and rotor cores of brushless DC motors. The 0.2mm thickness is specifically designed for high‑frequency operation (20kHz–50kHz) common in FPV drones and high‑speed UAVs. Each lamination is coated with an insulating layer to suppress eddy currents and minimize hysteresis loss. Reenives uses fully processed non‑grain oriented (NGO) silicon steel grade 20PN1200, offering ultra‑low core loss (≤9.5 W/kg @1.0T/1000Hz), high permeability, and excellent mechanical strength for demanding flight conditions.

📂 Classification of 0.2mm Laminated Silicon Steel for Drone Motors

Based on coating type, magnetic grade, and stacking method, Reenives offers several variants to match specific motor designs:

• By thickness: 0.20mm (high‑frequency, drone/UAV), 0.35mm (general BLDC), 0.50mm (industrial).
• By insulation coating: C3 (thin organic), C5 (epoxy + inorganic, weldable), C6 (high insulation resistance), and full epoxy powder coating (superior corrosion protection for agricultural drones).
• By stacking technique: Interlocking (self‑bonded stacks), laser welding, or glued stacks – Reenives supports all three for different rotor/stator rigidity needs.
• By magnetic grade: 20PN1200 (lowest loss), 20PN1300, 20JNEH1200 (high permeability).

✈️ Applications – FPV Racing, UAV, Gimbal & Industrial BLDC Motors

The 0.2mm laminated silicon steel from Reenives is ideal for high‑frequency, high‑acceleration environments:

• FPV racing drone motors (2207, 2306, 2507) – ultra‑low eddy loss for rapid throttle response.
• Cinematic UAVs & heavy‑lift drones – high torque density with reduced heat generation.
• 3‑axis gimbal motors – smooth, vibration‑free rotation thanks to minimized cogging.
• Rotor cores for axial‑flux motors – excellent magnetic properties for compact designs.
• Industrial servo drives & e‑scooter motors – universal compatibility with any BLDC platform.

⚙️ Engineer’s 6‑Step Selection Guide for 0.2mm Laminated Silicon Steel Cores

Optimize your motor design by following these technical steps:

1. Define motor electrical frequency & RPM: For operating frequency >20kHz (common in FPV), mandatory use of 0.20mm laminations.
2. Calculate required saturation flux density: Choose grade 20PN1200 or 20JNEH1200 for B50 ≥1.70T to maximize peak torque.
3. Select stacking geometry (stator/rotor): Provide inner diameter (shaft), outer diameter, slot/tooth profile. Reenives supports private mould development with no NDA complexity.
4. Choose coating & insulation type: C5 epoxy for standard drone applications; full epoxy powder coating for high‑humidity or salt‑fog environments (e.g., coastal Turkey).
5. Request electromagnetic FEA simulation: Reenives provides JMAG-based core loss and torque ripple analysis free of charge for qualified projects.
6. Order prototype samples: Lead time 10–12 days for 0.2mm laminated stacks, with full dimensional report and Epstein test certificate.

📌 Pro tip: Combining 0.2mm stator laminations with Reenives’ epoxy coating reduces inter‑lamination short circuits, improving motor efficiency by 3–5% in real‑world drone flights.
