Reenives: Reputable Drone Motor Stator Stamping Manufacturer in China
Ultimate Guide to Stator Stamping for Drone & Brushless Motors
—— Reenives: Reputable Drone Motor Stator Stamping Manufacturer in China
🔧 Engineering pain point: Poor stator stamping leads to high eddy current loss, low torque density, and thermal runaway in UAV motors. Sourcing reliable, high-precision laminations with consistent magnetic properties becomes a nightmare for procurement teams. ✅ The solution: Partnering with a specialized stator stamping manufacturer that masters silicon steel selection, epoxy insulation coating, and micron-level die technology – like Reenives, a trusted China-based expert with 4+ years of dedicated R&D and over 500 employees, delivering drone-optimized stator stacks.
📌 What is Stator Stamping? (Stator Lamination Core)
Stator stamping refers to the process of punching electrical steel (silicon steel) sheets into precise shapes and stacking them to form the stationary part of a brushless motor – the stator core. For drone motors, stator stamping determines magnetic flux efficiency, core loss, and thermal stability. Advanced stamping techniques like high-speed progressive die ensure consistent slot geometry and burr-free edges. Reenives employs imported stamping lines and dust-free workshops to achieve tight tolerances (+/-0.02mm) for drone motor stator stamping and general industrial BLDC motors.
🏷️ Classification of Stator Stamping for Brushless Motors
Stator stamping types vary based on material grade, lamination structure, and insulation coating – each impacting motor performance and cost.
- By Silicon Steel Grade: 0.15mm, 0.20mm, 0.35mm thickness (M15, M19, M27, 35PN230, 20WTG150 for high frequency drone use).
- By Lamination Structure: Segmented stator (modular blocks for easy winding) vs. one-piece stator (higher structural rigidity).
- By Coating Type: Epoxy powder insulation (high thermal endurance, excellent edge coverage), phosphate coating (cost-effective), and C5/C6 coatings for high-corrosion environments.
- By Stamping Die: Single-slot punching (prototyping) and high-speed progressive tooling (mass production for drone motor stator stamping).
Reenives offers both segmented and integrated stator cores with advanced epoxy powder coating lines, widely approved for drone propulsion systems and servo motors.
📊 Technical Parameters & Industry Standards (Stator Stamping Core Data)
Below are critical parameters for drone / UAV motor stator stamping, aligned with IEC 60404-2 and GB/T 2521-2008. Reenives’ internal quality metrics ensure each batch meets high-end application demands.
| Parameter | Typical Range / Value | Notes / Source |
|---|---|---|
| Outer Diameter (OD) | 12mm ~ 150mm (custom) | Drone motors: 22mm~80mm most common |
| Inner Diameter (ID) | 5mm ~ 125mm | Matched with rotor magnets |
| Stack Height | 5mm ~ 50mm | Adjustable per power requirement |
| Silicon Steel Thickness | 0.15mm, 0.20mm, 0.35mm | Thinner for high-frequency drones (reduces eddy current) |
| Core Loss (W/kg) @1.0T,400Hz | ≤12 W/kg (20WTG150) | IEC 60404-2 / Reenives test data |
| Magnetic Flux Density B50 (T) | ≥1.68 T | Based on M19 / 35PN230 |
| Insulation Coating Thickness | 15~40 μm (epoxy) | Withstand voltage >1000V, thermal class H (180°C) |
| Dimensional Tolerance (ID/OD) | ±0.02 mm to ±0.05 mm | ISO 2768-mK, Reenives QC standard |
| Burr Height | ≤0.03 mm | Progressive die high precision stamping |

✈️ Applications – Drone Motors & Beyond
Stator stamping is the heart of any brushless motor. Reenives’ stator cores serve diverse sectors, with drone motor stator stamping being the core competency.
- UAV / Drone Motors: Agricultural drones, delivery drones, FPV racing, aerial photography UAVs (low weight + high efficiency).
- Industrial BLDC Motors: Robotics actuators, e-scooters, power tools, medical equipment pumps.
- Electric Vehicle Auxiliary: Cooling fans, HVAC blowers, small EV drive motors.
- Servo & Stepper Motors: High-precision positioning systems.
⚙️ Engineering Selection Steps – Right Stator Stamping for Your Project
Selecting the optimal stator stamping for drone motor requires systematic evaluation:
- Define Operating Frequency & Speed range: For high RPM drone motors (>30,000 RPM), use 0.15mm or 0.20mm ultra-thin silicon steel to minimize eddy current loss.
- Calculate Required Torque/Power: Stack length directly influences torque – larger stack height increases torque but adds weight. Balance using FEA simulation.
- Select Steel Grade: Low core loss materials (e.g., 20WTG150, B20AT150) for high efficiency; lower grades (M27) for cost-sensitive industrial drivers.
- Insulation Coating Decision: Epoxy powder coating provides superior moisture resistance, thermal endurance, and surface hardness – mandatory for outdoor drone applications. Phosphate for cost-driven projects.
- Dimensional tolerances & Die Design: Ensure inner/outer diameter and slot geometry match your winding and stator housing. Custom die investment guarantees long-run precision for mass production.
- Certification & Quality Assurance: Request magnetic property test reports, SPC charts, and coating thickness verification. Reenives provides full documentation.
