DRONE & eVTOL MOTOR SOLUTIONS
ULTRA-LIGHTWEIGHT MOTOR CORE STAMPING FOR DRONES & UAVs
Elevate payload capacity, flight endurance, and thermal stability for next-generation UAVs, FPVs, and eVTOL aircraft. We specialize in sub-micron stamping of ultra-thin electrical steel (0.15mm – 0.20mm) for high-RPM brushless drone motors. Driven by our optical-ground carbide progressive dies and advanced adhesive bonding technologies, we deliver zero-burr, high-torque stator and rotor cores engineered for the skies.
THE AERIAL EFFICIENCY CHALLENGE
MAXIMIZING FLIGHT TIME WITH ULTRA-THIN 0.15MM SILICON STEEL
UAV and eVTOL motors operate at violent acceleration rates and high RPMs, where high-frequency iron losses rapidly generate heat, draining battery power and risking in-flight motor burnout. The solution is stamping ultra-thin 0.15mm to 0.20mm silicon steel. However, stamping such delicate material without tearing or burring requires sub-micron die clearances. Our specialized carbide stamping dies maintain a strict <0.005mm burr threshold, drastically reducing eddy currents and extending your drone’s flight time.

EXPERT ANSWERS ON UAV & eVTOL MOTOR CORES
Have technical questions about stamping 0.15mm silicon steel, self-bonding technology, or prototyping eVTOL motor cores? Review our FAQs below or contact our aerospace engineers directly.
Why is 0.15mm or 0.20mm silicon steel necessary for drone motors?
Drone motors spin at extremely high RPMs (often 10,000 to 50,000+ RPM). Iron eddy current losses increase quadratically with frequency and thickness. Using 0.15mm or 0.20mm ultra-thin steel drastically reduces eddy current heat, allowing the motor to run cooler, output higher torque, and save battery energy for longer flight times.
Why is Backlack (adhesive bonding) better than interlocking for UAV motor rotors?
Interlocking tabs create localized magnetic bottlenecks and mechanical stress, which degrade efficiency and can cause balance issues at 30,000+ RPM. Backlack uses a heat-cured adhesive layer across the entire lamination surface, providing 100% uniform bonding without damaging insulation or introducing mechanical imbalance.
Can you stamp Cobalt-Iron (Hiperco) alloys for aerospace drone motors?
Yes. Cobalt-Iron alloys provide the highest magnetic saturation of any commercial material, making them ideal when thrust-to-weight ratio is paramount. We build specialized carbide tooling specifically calibrated for the unique mechanical properties of cobalt-iron alloys.
How do you support prototype validation for new eVTOL or drone motor designs?
UAV design iterations are fast. We provide precision wire-EDM and high-speed laser cutting services to produce low-volume (10 to 500 pcs) prototypes from 0.15mm/0.20mm steel. This allows your team to test thrust, thermal limits, and efficiency before committing to a mass-production progressive die.
