Reenives: Global Leading BLDC AC Motor Stator Supplier
AC Motor Stator for UAV & BLDC Motors | Reenives: Global Leading BLDC AC Motor Stator Supplier
Designing a high‑efficiency UAV propulsion system? Standard AC motor stators often suffer from high core loss, thermal drift, and torque ripple that limit flight endurance. Reenives engineers AC motor stators with low‑loss silicon steel, precision epoxy insulation, and custom slot geometries—cutting eddy current losses by up to 34% in real‑world drone tests. Trusted by 1000+ enterprises, we deliver BLDC AC motor stators optimized for 40‑80 kHz PWM and aggressive power‑to‑weight ratios.

What is an AC Motor Stator?
An AC motor stator is the stationary core component that generates a rotating magnetic field when excited by alternating current. In BLDC motors (used widely in UAVs), the stator consists of laminated silicon steel stacks with windings, designed to minimize eddy current and hysteresis losses. Advanced AC motor stators use non‑grain oriented electrical steel (0.20mm / 0.35mm) and epoxy powder coating to ensure high dielectric strength and thermal stability. Reenives specializes in producing custom AC motor stators for drone propulsion, e‑mobility, and industrial servos, with a focus on high torque density and minimal cogging.

5‑Step Engineering Selection Guide for AC Motor Stator Laminations
- Define motor OD & stack height: Based on required torque, KV rating, and power density (e.g., 2808 stator for 7‑inch FPV).
- Select lamination material: 0.20mm for high‑frequency (40‑80kHz PWM) / 0.35mm for robust industrial drones.
- Choose slot & pole combination: 9N12P for high RPM, 12N14P for balanced performance, 18N24P for peak torque.
- Define insulation type: Epoxy powder coating is mandatory for UAV stators to prevent inter‑lamination shorts under humidity.
- Prototype & validation: We supply 10‑25 sample pieces for back‑EMF, thermal, and efficiency testing before mass production.
