Engineers developing stamped motor solutions often face inconsistent lamination quality, high iron losses, and poor insulation that limit motor efficiency. For drone propulsion and high-speed BLDC systems, every watt counts. Reenives solves these pain points with high-volume progressive die stamped stators, achieving burr-free precision (≤0.025mm), consistent magnetic properties, and epoxy powder coating for superior thermal endurance. Our stamped motor stator cores help increase overall motor efficiency by up to 18% while reducing manufacturing tolerances.

⚙️ What is a Stamped Motor Stator Core?

A stamped motor stator core is manufactured from thin silicon steel laminations produced via high-speed progressive stamping dies. Each lamination is stacked and bonded or welded, forming the stationary magnetic circuit for brushless DC motors. For drone motors (UAVs), the stamped geometry ensures consistent air gap and reduced cogging torque. Reenives utilizes 0.2mm / 0.35mm electrical steel with vacuum annealing to guarantee low hysteresis loss, crucial for 100W–500W power range motors.

🔧 5-Step Stamped Motor Stator Core Selection for Engineers

1. Define electrical frequency & operating speed: For drone motors (10k–30k RPM) specify 0.2mm laminations to minimize eddy current loss.
2. Choose outer diameter & stack length: based on required torque constant (Kt) and power rating. Reenives provides design FEA support.
3. Specify insulation type: epoxy powder coating recommended for high humidity and dust environments (drones/outdoor).
4. Review tooling & die compatibility: For custom stamped designs, private mould development is available (low NRE cost).
5. Request stamped core samples & perform core loss verification. Reenives ships free evaluation samples to qualified OEMs.
