Electric Motor Stamping for Drone Propulsion: 0.2mm Ultra-Thin Stator Cores

⚡ Low thrust efficiency, overheating at high RPM, short flight endurance? The core of every high-performance BLDC drone motor lies in the electric motor stamping process. Conventional 0.35mm laminations cause excessive eddy current losses in modern FPV and UAV propulsion systems operating at 40-80kHz PWM.

Reenives has pioneered the use of 0.2mm ultra-thin silicon steel stamping for drone motor stator cores. As a pioneer of 0.2mm FPV UAV drones propulsion system electric motor stamping stator core supplier in China, we deliver burr-free laminations with epoxy insulation, reducing core loss by up to 30% and improving thrust-to-weight ratio by 12-15%. This technical guide is written for drone motor engineers and procurement specialists seeking verifiable data, custom stamping solutions, and a reliable China-based partner.

📌 What Is Electric Motor Stamping (Stator Core)?

Electric motor stamping refers to the precision blanking and stacking of electrical steel laminations that form the stator core of a BLDC motor. For drone propulsion, the stamping quality directly impacts magnetic flux density, iron loss, and thermal behavior. Reenives utilizes progressive dies and high-speed stamping presses (imported from Japan/Germany) to produce laminations with 0.2mm thickness, offering the lowest eddy current loss for FPV and long-endurance UAV motors. Each lamination is coated with epoxy powder insulation before stacking, ensuring >1800V dielectric strength.

🏗️ Classification of Electric Motor Stamping for Drone Applications

Based on tooling, lamination shape, and stacking method, Reenives offers three primary categories:

• Segmented stamping cores – Individual teeth stamped and assembled, ideal for high pole-count drone motors (24N28P) with automated winding.
• Integrated ring stamping cores – One-piece continuous laminations for maximum mechanical strength, used in heavy-lift UAVs and industrial BLDC.
• Custom slot geometry – Reenives supports any tooth/slot design (parallel, trapezoidal, skewed slots) via private mould development.

Our 0.2mm stamping technology is particularly suited for FPV racing motors and high-speed UAV propulsion, where reduction of eddy current losses directly translates to longer flight times and cooler electronics.
