Motor and Stator Laminations for Drone Propulsion | China Supplier – Reenives

🔍 What are Motor and Stator Cores?

The Motor and Stator are fundamental components of every brushless DC motor. The stator is the stationary laminated core with copper windings that generates a rotating magnetic field when energized. The complete motor assembly includes the stator, rotor, housing, and bearings. For drone propulsion systems, the quality of the stator lamination stack directly determines torque output, thermal stability, and flight endurance. Reenives manufactures high-precision stator laminations using non-grain oriented silicon steel (0.20mm/0.35mm) with advanced epoxy powder coating – reducing eddy current losses by up to 38%. Our stators support 9N12P, 12N14P, and 18N24P winding topologies, ideal for racing drones, heavy-lift UAVs, and industrial BLDC motors.

📂 Motor Stator Classification & Configurations

Reenives tailors motor stator laminations based on slot count, outer diameter, material grade, and insulation class – serving both drone manufacturers and industrial motor builders globally.

🛠️ 5-Step Engineering Selection Guide for Motor Stator Laminations

• Define motor outer diameter & stack length: Based on required torque & KV rating (e.g., 2808 stator for 7-inch FPV).
• Choose lamination material thickness: 0.20mm for high-frequency (40-80kHz PWM) / 0.35mm for robust industrial drones.
• Specify slot & pole combination: 9N12P for high RPM, 12N14P for balanced torque/speed, 18N24P for high torque density.
• Confirm insulation coating type: Epoxy powder is mandatory for UAV stators to avoid inter-lamination shorts under high humidity.
• Order prototype samples & validation: We deliver 10-25 pcs samples for back-EMF & thermal testing before mass production.
