What is a Slinky Stator?
A Slinky Stator refers to a stator core manufactured using an innovative in‑plane helical winding process that forms continuous laminations from electrical steel strips. Unlike conventional stamping—which can waste up to 70% of material—the Slinky method reduces scrap to just 10‑30%, offering significant material savings and design flexibility for high‑performance motors .
For UAV brushless motors, the Slinky Stator delivers exceptional magnetic performance, especially when using non‑grain oriented silicon steel (0.20mm / 0.35mm) with epoxy powder coating to minimize eddy current losses at high PWM frequencies (40‑80 kHz). Reenives has adapted this technology to produce precision Slinky Stator laminations for drone propulsion, robotics, and industrial BLDC motors.

5‑Step Engineering Selection Guide for Slinky Stator Laminations
- Define motor OD & 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.
