Motor Rotor Stator Laminations for Drone Propulsion Systems | Leading China Supplier – Reenives

🔍 What are Motor Rotor Stator Cores?

The Motor Rotor Stator assembly forms the complete electromagnetic circuit in every brushless DC motor. The stator (stationary laminated stack with copper windings) generates a rotating magnetic field, while the rotor (permanent magnet carrier or laminated stack) converts that field into mechanical torque. For drone propulsion systems, precision-matched rotor and stator laminations directly determine thrust-to-weight ratio, thermal stability, and flight endurance. Reenives manufactures high-quality rotor and stator stacks using non-grain oriented silicon steel (0.20mm/0.35mm) with advanced epoxy powder coating – reducing eddy current losses by up to 38%. Our laminations support 9N12P, 12N14P, and 18N24P topologies, ideal for racing drones, heavy-lift UAVs, and industrial BLDC motors.

📂 Rotor & Stator Lamination Classifications

Reenives tailors both rotor and stator laminations based on geometry, material grade, and insulation – ensuring perfect electromagnetic matching for your motor design.

🛠️ 5-Step Engineering Selection Guide for Rotor & 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 stator slot & pole combination: 9N12P for high RPM, 12N14P for balanced torque/speed.
• Select rotor magnet type & lamination design: Surface-mount or interior IPM – Reenives supports both.
• Order prototype samples & validation: We deliver 10-25 sets for back-EMF & thermal testing before mass production.
