For engineers designing high-performance stamping motor systems, poor lamination quality and inconsistent stamping tolerances lead to increased eddy current losses, thermal issues, and reduced torque density. Reenives addresses these challenges with advanced progressive die stamping technology, producing stamping motor stator cores with burr-free edges (≤0.025mm), uniform magnetic properties, and corrosion-resistant epoxy powder coating. Our stamping process improves motor efficiency by up to 17% while ensuring repeatability for high-volume production.

⚙️ What is a Stamping Motor Stator Core?

A stamping motor stator core is manufactured via high-speed progressive stamping dies using thin-gauge electrical steel laminations. These laminations are stacked and bonded (or welded) to create the stationary electromagnetic circuit for brushless DC motors. For drone motors (UAVs), stamping motor cores demand exceptional dimensional consistency to minimize cogging torque and maximize power density. Reenives uses 0.2mm / 0.35mm non-grain oriented silicon steel with vacuum annealing, delivering core loss as low as 2.5 W/kg @50Hz for industrial BLDC and high-frequency capability for drone propulsion.

🔧 5-Step Stamping 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. Determine outer diameter & stack length: Based on torque constant (Kt) and power rating. Reenives provides free FEA support.
3. Specify insulation type: Epoxy powder coating is recommended for high humidity/dust environments (drones/outdoor).
4. Review tooling & die compatibility: For custom stamped designs, private mould development available (low NRE cost).
5. Request stamping core samples & perform core loss verification. Reenives ships free evaluation samples to qualified OEMs.
