ECMpowered Motor Design for Aerospace & Defence
Compact Power
ECMpowered motors deliver high torque and power density with minimal mass—enabling lighter systems, greater payload capacity, and extended range.
Built for Harsh Environments
Encapsulated stators, advanced thermal management, and a simplified mechanical design ensure reliable performance in high-vibration, extreme-temperature, sealed, and submerged environments.
Ultra-Low Noise & EMI
PCB Stator motors operate without cogging or iron-induced vibration—reducing EMI and mechanical noise by up to 30 dB, ideal for missions that require stealth, and utilize onboard sensors (side scan sonar, etc.).
Precisely Tuned Performance
Using PrintStator, motors are custom designed for exact torque, duty cycle, and envelope needs—optimizing efficiency and eliminating overengineering.
