DC Stator Laminations for Drone Propulsion Systems | Reliable DC Stator Core Manufacturer in China – Reenives

🔍 What is a DC Stator? (Core of Brushless DC Motors)

The DC Stator is the stationary laminated stack in a brushless DC motor (BLDC) that generates a rotating magnetic field. For drone propulsion systems, stator lamination quality directly determines thrust efficiency, thermal stability, and overall reliability. Reenives manufactures high-precision DC stator cores using non-grain oriented silicon steel (0.20mm/0.35mm) with advanced epoxy powder coating – reducing eddy current losses by up to 38% compared to conventional insulation methods. Our stators support 9N12P, 12N14P, 18N24P winding topologies, ideal for racing drones, heavy-lift UAVs, and industrial BLDC motors.

📂 DC Stator Classification & Lam Stack Configurations

Reenives tailors 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 DC 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.
• Confirm insulation coating type: Epoxy powder is mandatory for UAV stators to avoid inter-lamination shorts under high humidity.
• Customize slot & tooth geometry: Reenives supports private mould with tailored slot fill factor optimization.
• Order prototype samples & validation: We deliver 10-25 pcs samples for back-EMF & thermal testing before mass production.
