Three Phase Motor Stator Stacks for BLDC Drone Motors | China Supplier – Reenives

🔍 What is a Three Phase Motor Stator Core?

The Three Phase Motor Stator is the stationary laminated electromagnetic component in every three-phase brushless DC motor (BLDC). It consists of a stacked silicon steel core with multiple slots where copper windings are inserted. When energized by a three-phase ESC, it generates a rotating magnetic field that drives the rotor. For drone propulsion systems, the quality of the three phase motor stator stack directly determines torque ripple, thermal stability, and overall flight efficiency. Reenives manufactures high-precision three phase 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 stators support 9N12P, 12N14P, 18N24P winding topologies, ideal for racing drones, heavy-lift UAVs, and industrial BLDC motors.

🛠️ 5-Step Engineering Selection Guide for Three Phase Motor Stator Stacks

• 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.
