Patented Motor Technology by eMotres
AeroStator Core — eMotres patented motor stator

AeroStator
Core

Four patented technologies in one motor architecture — the stator platform behind every eMotres motor. The highest torque density electric motor available on the market, built for drones, UAVs, aviation and robotics.

CIANO14: 6 kW/kg — more than 2× the continuous power of any competitor in its class. Same size, double the sustained output.

What's inside

Four technologies.
One stator.

Every eMotres motor integrates three patented innovations that work together to push torque density beyond what conventional designs can achieve.

Full technology overview
Best-in-class Air & Liquid Cooling
Best-in-class Air & Liquid Cooling
Cutouts directly above each coil give cooling air or liquid the shortest possible thermal path from winding to cooler — no thick yoke barrier in between. Surface area is 2× larger than a standard stator.
Tangential Magnetization
Tangential Magnetization
Flux concentration beyond standard Halbach arrays — no adhesive, easy re-magnetization.
Rectangular Copper Wire
Rectangular Copper Wire
~75% fill factor. Lower resistance, higher current density, less heat.
Single Layer Winding
Single Layer Winding
2× fewer coils than standard designs — less winding time, lower production cost, higher reliability.
