⚙️ What is a 1202.5 Brushless Motor Stator Core?

The 1202.5 brushless motor stator core is a compact laminated magnetic core designed for micro drone motors. The designation "1202.5" typically refers to a motor with a stator outer diameter of approximately 12mm and a stator stack height of 2.5mm — a popular size for sub-100g drones, micro FPV racers, and lightweight UAVs. Despite its small footprint, this stator core must deliver high torque density, low iron loss, and excellent thermal dissipation to support efficient flight. Reenives manufactures 1202.5 stator cores from ultra-thin non-oriented silicon steel (0.20mm) with advanced epoxy powder coating, ensuring minimal eddy current loss and consistent magnetic performance. With precise stacking and vacuum annealing, our 1202.5 stators achieve saturation flux density ≥1.65T and iron loss ≤9W/kg (@400Hz) – critical for extended flight times and responsive throttle control in micro drones.

📂 1202.5 Stator Core Classification – Tailored to Micro Drone Needs

Reenives classifies 1202.5 stator cores based on lamination material, coating, and slot geometry to meet diverse engineering requirements:

Micro Drone Series (0.20mm ultra-thin): Optimized for 5000KV–8000KV motors, iron loss ≤9W/kg @400Hz, ideal for 1S-2S micro FPV drones.
High-Efficiency Series (0.15mm optional): For extended flight time applications, offering 15% lower eddy loss than 0.20mm.
Custom Slot Geometry: Supports 9N12P, 12N14P, and proprietary pole/slot combinations for specialized torque curves.

✅ Why Reenives 1202.5 stators are trusted: Each lamination undergoes burr-free stamping (burr <0.015mm), stress-relief annealing, and C5 epoxy coating. This ensures inter-lamination resistance >1 MΩ and salt spray resistance >96h – critical for micro drones operating in varied environments.

🧭 Step-by-Step Guide to Selecting Your 1202.5 Stator Core

Step 1 – Determine target KV and operating voltage. For 1S (3.7V) micro drones, higher KV (6000–8000) is common; choose 0.20mm laminations to balance loss and cost.

Step 2 – Define slot/pole combination. 9N12P offers smooth torque for micro drones; 12N14P provides higher torque density. Reenives can simulate both.

Step 3 – Specify stack height & tolerance. Standard 2.5mm height; custom heights available for different power requirements.

Step 4 – Insulation & environmental requirements. Epoxy coating is recommended for outdoor drone use to prevent corrosion and inter-lamination shorts.

Step 5 – Prototype and validate. Reenives offers free samples (up to 10pcs) with core loss test and dimensional report. Your 1202.5 stator is guaranteed.

❓ FAQ – 1202.5 Brushless Motor Stator Core Engineering Insights

1. What KV range is suitable for a 1202.5 stator core in micro drones?

Typically 5000KV–8000KV for 1S (3.7V) and 2S (7.4V) micro drones. Higher KV suits lightweight racing frames; lower KV is better for whoop-style cinewhoops. Source: Reenives application engineering guide.

2. What is the typical iron loss for a 1202.5 stator core at 400Hz?

For 0.20mm laminations, iron loss is ≤9.5 W/kg @1.0T, 400Hz. Using 0.15mm laminations can reduce loss by approximately 15%. Source: Parameter table above.

3. Can I get a 1202.5 stator core with a non-standard stack height or slot geometry?

Yes. Reenives supports custom stack heights (e.g., 2.0mm, 3.0mm) and proprietary slot designs. Minimum order for custom tooling starts at 2,000 units. Source: Reenives OEM service.

4. Why is epoxy powder coating important for 1202.5 stator cores in drone motors?

Epoxy coating prevents inter-lamination short circuits, increases insulation resistance to >100MΩ, and provides corrosion resistance (salt spray >96h). This ensures reliable performance in outdoor and humid conditions. Source: Coating test based on ASTM B117.

5. What quality documents are included with bulk 1202.5 stator core orders?

Each shipment includes material certificate (EN 10204 3.1), core loss test report, dimensional inspection report, and coating hi-pot record. Reenives is ISO 9001:2015 certified. Source: Company quality assurance system.
