Motor Rotor Stator Laminations for UAV FPV Drone Propulsion Systems | High-Performance Brushless Motor Cores

🔧 What is Motor Rotor Stator Core? (Precision Lamination for UAV Motors)

The Motor Rotor Stator assembly forms the electromagnetic heart of any brushless DC motor. In UAV/FPV drone propulsion systems, the stator core (stationary laminated stack) interacts with the rotor’s permanent magnets to generate torque. Reenives specializes in high-grade silicon steel laminations, epoxy powder coated for insulation, reducing eddy current losses by up to 35% compared to conventional stampings. Our stator cores are designed for 12N14P, 9N12P, and 24N28P topologies – critical for responsive drone flight and endurance.

📂 Classification of Motor Rotor Stator Laminations

Based on slot geometry, outer diameter, and coating type, Reenives supplies tailor-made stator cores suitable for UAV propulsion, automotive auxiliary motors, and industrial servos. Core classifications include:

📊 Technical Parameters & Sourcing Data (Certified Lab Tested)

Data sourced from Reenives in-house R&D lab and third-party verification (TÜV report available). All values meet or exceed UAV motor requirements for minimal core loss.

✔️ Source: Reenives internal quality report & ISO 9001:2025 certified production – each batch undergoes eddy current testing and dimensional validation.

✈️ Applications: UAV, FPV Drone & Industrial Brushless Motors

Our Motor Rotor Stator laminations are engineered for high-thrust, lightweight propulsion systems. Typical use cases:

• FPV Racing Drones: 22xx – 25xx stator with low inertia for instant throttle response.
• Commercial Survey UAVs: High-efficiency 28mm-40mm stators delivering 20+ min flight time.
• Agri-drones & Heavy-lift: multi-stack rotor stator combination for 15-30kg payload motors.
• E-bike / E-scooter BLDC: universal compatibility with common brushless motor platforms.
• Robotic actuators & servo motors: ultra-low cogging torque stator designs.

🛠️ 5-Step Selection Guide for Engineers & Procurement Teams

• Define motor outer diameter & stack length: Based on drone thrust requirement (e.g., 2306 stator for 5-inch FPV).
• Select lamination material grade: 0.2mm for high-frequency (20kHz+ PWM) or 0.35mm for cost-effective endurance.
• Choose coating & insulation: Epoxy powder coating is mandatory for UAV stators to prevent inter-lamination shorts.
• Customize slot/pole combination: Reenives supports private mould development for 9N12P, 12N14P, 18N24P patterns.
• Request prototype samples: Validate fit, thermal performance, and back-EMF before mass production.
